Product overview The generator enables you to test a broad range of video displays including composite or component television video signals as well as computer video display terminals. The generator enables you to quickly set the format appropriate for each display simply by twisting a knob. The generator’s functions can be customized to support video display testing in a variety of environments such as development, repair center, or production line.
• High Bandwidth Digital Content Protection (HDCP). Generates HDCP encrypted content for testing DDCP-compliant displays. • DVI or HDMI Analyzer. Optional receiver, which measures pixel errors at different frequencies, measures timing of external sources, and displays EDID from external sources. Can also be used to test cables or distribution systems. • High Definition Multimedia Interface (HDMI).
Operating the generator This section describes basic operating procedures. There are four operational interfaces for controlling the generator. • Physical controls. Most of the generator’s features and functions are supported using the front panel using the knobs and keys. Functions which are not supported using the front panel include upgrading the firmware, creating and editing formats, creating and editing images and reconfiguring the format and image knob lists. • Command line.
Image knob The Image knob is used to select a test image from a list of stored images. The exact behavior of the knob depends upon the status of the Image key. Turning the knob when the light on the Image key is extinguished scrolls through the main list of test images. Not all images are supported by all signal formats. Some images in the main image list may be skipped while certain formats are selected. For example, the ColorBar image will be skipped whenever a monochrome format is selected.
R, G, B Video Gate keys The Video Gate keys activate (turn on) or deactivate (turn off) individual color elements when the generator is in normal operating mode. They also control the addition of primary color information to the NTSC / PAL video outputs on the generator. The following table shows the function of the Video Gate keys, and commands for controlling the key function. Key Function Command R Turns all of the red video outputs on and off.
Outputs Key The Outputs key turns all signal outputs on or off when the generator is in normal operating mode. This is the master output signal control. When the master output control is turned off, all of the signal outputs (video and sync) of the generator are disabled. Key Function Command ON Toggles on and off all video and sync.
• M for monochrome video • C for RGB color video • Y for YPrPb (analog) or YCrCb (digital) with 4:4:4 color sampling • y for YCrCb (digital) with 4:2:2 color sampling To use Status Display mode: 1. Turn off the generator. 2. Hold down the Step, G, and B keys while starting the generator, until status display displays.
Video interfaces This section describes the video interfaces available on the generator. VGA interface Use to output analog video for testing analog video displays. The following table describes the VGA connector pinouts.
LVDS interface The LVDS connector is located on the front of the generator and is labeled “Digital.” It emulates a digital host video source and is used for testing LVDS-compliant video displays. The LVDS connector pinouts are shown in the following table.
Composite video BNC If your generator is equipped with the TV option, it will have a composite TV BNC connector on the right side, labeled “TV.” This interface emulates an analog composite TV source. Component video BNC interface Your generator can be optionally equipped with separate R. G, B, HS/CS, and VS BNC connectors on the right side. These interfaces emulate component a analog video source.
Computer interfaces This section describes the RS-232, GPIB, and USB interfaces. RS-232 interface Each generator has a standard RS-232 serial connector, labeled “Serial.” This is a 9-pin D-Sub male connector which enables you to connect the generator with a computer. A null modem cable is provided to support this interface. You can communicate with the generator either through the command line interface from a telnet session or from the Video Generator Manager (VGM) application.
PCMCIA interface Use the PCMCIA card slot to back up your custom configurations, transfer configurations and settings from one generator to another, and store bitmap images.
Command interfaces The common test applications can be accomplished through the physical controls or through the command line interface. The generator supports an ASCII command and query language that allows you to control the generator interactively or through batch processing of command files. All generator functions are supported through this interface. The command interface is available through two physical interfaces: the RS-232 interface and the optional IEEE-488 GPIB interface.
Changing the baud rate The RS-232 interface can be configured from the physical controls to support faster baud rates and to supprort a remote keypad (optional accessory). The default configuration is 2400 baud. When the generator is powered on, the baud rate returns to the default configuration. To support file transfers, you can change the baud rate of the port to 38400 bps using the command line interface or 9600 bps using the physical controls.
• To apply the format to the generator hardware, enter: FMTU • To load an image, enter: IMGL image_name • To apply the image to the generator hardware, enter: IMGU To send multiple queries and commands to the generator: 1. Establish a terminal session with the generator (see page 14). 2. At the R:> prompt, enter the queries or commands, separating each with a semi-colon and terminating the command line with a carriage return.
3. At the R:> prompt, transfer the text file to the generator. For example, to transfer a file using HyperTerminal, do the following: a. On the Transfer menu, click Send Text File. The Send Text File dialog box appears. b. Select the text file you want to send, and then click Open. HyperTerminal displays the commands as they are sent. c. Press Enter once to ensure that the last command is sent.
Special operating modes You can set the generator to operate in various modes to accomplish specific functions. When any special operational mode is set, it persists (until overridden) throughout subsequent power cycles, which may be performed to set other modes. You can view the operational settings and special functions of the generator on a video display by viewing the GenOps image. This image provides key sequences and the status of special operating modes in the generator.
Summary of special modes The following table describes the special operating modes, and how to configure the modes using the physical controls or the command line interface.

To display information about generator: 1. Connect the generator with a display. 2. Choose a format supported by the display. 3. Turn the Image knob to select the GenStats image.
Restoring factory settings This section describes how to set and restore the generator system parameters. System Parameters The following system parameters are stored in the 802’s non-volatile system memory: • The reference rate calibration factor. The 802 uses a crystal controlled oscillator as the reference for all timing signals. The crystal frequency has a maximum error of ±50 ppm.
To re-initialize generator through system reset: 1. Hold down ACS and DSS while powering up the generator. A confirmation message is displayed. 2. Press the Outputs key to continue, or press the Step key to cancel the operation. To re-initialize and calibrate the generator using command interface: 1. Establish a terminal session with the generator (see page 14). 2. Enter the following command: INIT The generator then goes through a complete self-test and self-calibration procedure.
Calibrating the generator The 802BT/R generator can calibrate itself. Once calibrated, the generator does not require periodic calibration. There are no physical controls to adjust. All calibration is electronic. Calibration factors are saved in non-volatile memory. The calibration accuracy of the generator for analog video voltage swing is specified to be ±14mV (or ±2% for a nominal 700mV signal).
CALF? The generator presents the following in response: 1089, 2589, 1993, 3223, 1148, 2633, 2059, 3279, 1000, 2505, 1990, 3219, 793, 787, 3382, 3509 Calibrating frequency All frequencies associated with the generator are derived from a common frequency reference, which can be calibrated using the rate calibration command RATC. To reduce all frequency errors to zero: 1. Measure any convenient frequency from the generator using a very accurate frequency counter.
Cloning generators This section describes how to copy configuration settings from one generator to other generators using a PCMCIA card. The entire block of battery backed user memory (including video formats, custom test images and test sequences) is copied from one generator to another using a suitable PCMCIA memory card. The card you need is a Type 1, Battery Backed RAM PCMCIA card with at least 2 MB of storage. These cards are available from synchrotech P/N PCM-SRW-AM002 2MB.
Installing firmware Firmware upgrades are available at http://www.quantumdata.com/support/downloads/. Important: Always backup any custom objects (formats, images) stored on the generator before installing an upgrade. The firmware installation re-initializes the generator, which deletes any custom objects. After installing the firmware, you can restore custom objects. Firmware upgrades require the use of VGM. Please refer to the VGM online help for procedures on upgrading the generator.
Memory management The generator includes commands to manage its internal memory resources. These commands or useful if the generator exhibits degraded performance or other anomolies. To verify and correct memory related anomolies: 1.

4 Working with Formats Topics in this chapter: • Overview • Format library • Format naming conventions • Creating custom formats • Editing Format knob lists • Configuring DCS priority scheme • Creating format aliases 802BT/802R Video Test Generator User Guide 53
Overview The generators enable you to create your own formats and edit the Format knob list through the Video Generator Manager (VGM) application and the command line interface. Please refer to the VGM online help for details on procedures for these functions performed through VGM. This chapter provides procedures for customizing formats through the command line interface. The following functions are provided: 54 • Creating formats.
Format library The generator has a built-in library of formats. The same format library is used for all 802 models. The formats are stored in read-only memory (ROM) along with the generator’s operating code. Compatibility Some formats are for displays and graphics systems that may not be compatible with a specific generator model. Attempting to load an incompatible format will give you an error message.
Format naming conventions The names used in the built-in format library have been updated for the generator. Many format names on previous versions of the 802 generators have been renamed to more closely match the naming conventions used in the display industry or in the appropriate standards. There are three sets of naming conventions described in this section: 1) Composite television formats, 2) Component television formats, and 3) Computer display formats.
Common composite TV formats with sub-carriers and their respective standards: • NTSC - ITU-R BT.470-6 • NTSC# - SMPTE 170M • NTSC#KA - SMPTE 170M • PAL - ITU-R BT.470-6 • PAL# - ITU-R BT.470-6 • PAL#KA - ITU-R BT.470-6 • SECAM Component television format names Component television formats are named by their vertical resolution and scanning method. These formats apply to RGB, YPbPr, YcbCr and HD-SDI video.
Double clocking • i2x = double-clocked interlace (scene may change between fields) pixels are double-clocked for DVI compatibility) Frame rate Frame rate is optional. If no frame rate is given, then the frame rates are assumed.
• 12 for 1200 pixels • 30 for 3072 pixels Frame rate examples (half the field rate with interlace scanning) • 48 for 48Hz • 60 for 60Hz • 75 for 75Hz Aperture (used only when the aperture is not A) See “Aperture designators” on page 59. Common computer display formats • VSC1275 for Viewsonic 1280 by 1024 at 75 Hz • DMT0685 for Discrete Monitor Timing with 680 by 480 at 85 Hz Aperture designators Format names may include one or two characters that describe the aperture of the display.
• L = Letterbox (linear scale to fit one axis, center w/black bars in other) • Z = Zoom (blow- up to fill destination aperture with cropping, or LI ) • S = Scope (under-sample content horizontally) • W = Widescreen (over-sample content horizontally) • J = Justify (non- linear horizontal expand – more near edges) • K = Keep safe (shrink to avoid cropping – provide safe title) • P = Pan & Scan (truncate) • M = Mirror (horizontally – rear projection) Other Modifiers • I = Inverse (undo operato
Viewing the format library You can view the list of formats available in the generator using VGM or the command line interface. Please refer to the VGM online help for instructions on using VGM to view the format list. To display the format list: 1. Establish a terminal session with the generator. 2. Load the default format directory (fmt) or custom format directory by entering the following command: DIRL fmt 3.
2. Load the Format image. Information about the current format is displays. 3. Press the Step key, then turn Image knob to view additional formats. To display individual format parameters: 1. Establish a terminal session with the generator. 2. Load the format whose parameters you want to view by entering the following command: FMTL format; FMTU //specify a valid format name 3. Enter the format parameter(s) you want to view.
Creating custom formats You can create new signal formats for the generator and add them to non-volatile memory. You can create formats through VGM or by using a command line interface (either the RS-232 port or the IEEE-488 port). The recommended procedure for creating new formats is to use VGM. VGM contains the algorithms for ensuring compatibility between format parameters where there are dependencies in their respective values.
To create a new format: 1. Establish a terminal session with the generator. See “Setting up a terminal connection with the generator” on page 14. 2. Enter the following commands to initialize all parameters to default values and begin a format editing session: FMTN FMTB // initializes all parameters to default values // begins a format editing session 3. Enter the format parameter commands in sequence to set the values for the new format. HRES 654 . . .
6. Enter the following commands to load and begin editing the existing format. FMTL format_name FMTB // loads existing format into the format editor // begins a format editing session 7. Enter the format parameter commands in sequence where the new values differ from the existing format values. For example to modify the horizontal resolution enter the following command: HRES 654 Note: You do not need to enter parameter values if they match the existing format. 8.
FMTA new_fmt_name // saves format as new specified name 6. Assign the format to the knob list using these commands: DIRL FMT DIRB NAMI 20 new_fmt_name DIRE DIRS // // // // // loads format directory into edit buffer begins a directory edit session assigns new format to format knob list at 20 ends a directory editing session saves contents of directory as current name 7.
Editing Format knob lists Stepping through all of the available formats using the Format knob can be time consuming. This is particularly true if you regularly use only a few formats that may be scattered throughout the list. You can set up the 802 to show only the formats you want, in the order you want, when you turn the Format knob. The 802 maintains a list of these formats in non-volatile memory, and you can edit the list to include formats you have created and to remove any unneeded formats.
3. Press the Step key to start the Format List editor. The left side of the screen shows the current contents of the format list. The formats appear in the order that they are selected by the Format knob during normal operation. The right side of the screen shows the available formats. 4. Use the Format and Image knobs to select formats in the lists. Use these commands to edit the format list.

5 Working with Images Topics in this chapter: • Overview • Creating custom images • Downloading bitmap images from a PCMCIA card • Looping through images • Editing Image knob list • Creating image aliases 802BT/802R Video Test Generator User Guide 73
Overview The 802R/BT includes a library of 250 test images. In addition, you can create custom images, which consist of one or more drawing primitives, including single pixel dots, lines, rectangles, and ovals. You can select the grayscale and color tables used in the image and save the images in non-volatile memory. Custom images can be added to the list of built-in images that can be selected with the Image knob.
Creating custom images This section describes how to create images and add them to the generator’s image library, and how to customize the image list. The recommended method for creating images is create a text file containing the commands for creating the image, and then downloading the text file to the generator.
Command file example The following sample command file creates the image shown in the graphic below.
IMGE IMGA MyImage 802BT/802R Video Test Generator User Guide // end an editing session // save image as MyImage 77
Downloading bitmap images from a PCMCIA card This section describes how to store a bitmap image on a standard PCMCIA memory card, and then load the image as you would a built-in image. The generator can load only one image from a card. Although you can download an image using VGM, loading an image from a card is faster and easier. This feature is supported on 802BT and 802R generators with video board FPGA 91 or later, DVI daughter card FPGA 0xE3 or later, and firmware 7.3834000 or later (802BT) or 7.
Note: The card you need is a Type 1, Battery Backed RAM PCMCIA card with at least 2 MB of storage. These cards are available from synchrotech P/N PCM-SRW-AM002 2MB. Flash or compact type memory cards will not work. 2. Use one of the following procedures to configure the generator to use a format with the same pixel depth as the image: • Select a built-in format with the appropriate pixel depth. • Create a format with the appropriate pixel depth.
Looping through images You can set up a continuous cycling mode that draws all images in the image knob listone-after-another in an infinite loop. When activated, the message “Loop Enabled” appears on the display under test. To enable image looping: 1. Using the Format knob, select a format compatible with the display under test. 2. Turn the Image knob clockwise beyond the last image in the Image list about one turn. The message “Loop Enabled” appears on the display under test.
Editing Image knob list If your test environment requires only a subset of the available built-in images, you can configure the 802 to show only the images you want, in the order you want, when the Image knob is turned. The 802 maintains a list of these images in non-volatile memory. You can edit this list to include images you have created and to remove unneeded images.
Key Function Move (R) Moves the image selected in the image list to another position in the list. To move the selected image, press Move, use the Format knob to specify the new position, and then press the Move key again. Remove (DSS) Deletes the selected user-defined image from the list of available files. This will erase the entire contents of the file from non-volatile memory. Standard images cannot be deleted. 5. Press the Exit (Step) key to save the list and exit the editor.
DIRE DIRA new_img // ends the directory editing session // saves new image list as new_img To apply a new image knob list: IMGP new_img 802BT/802R Video Test Generator User Guide // loads image list new_img 83
Creating image aliases You can create image aliases to suit the needs of your site. Use the following procedure to create an alias for an image, save it to the image directory, and then use the image. To create and use an image alias: 1. Establish a terminal session with the generator. 2.
6 Working with Test Sequences Topics in this chapter: • Overview • Creating a test sequence • Viewing the test sequence list • Running a sequence 802BT/802R Video Test Generator User Guide 85
Overview When testing video displays, you typically select a format using the Format knob, and then select an image using the Image knob. In a production environment, where there might be a need to test several combinations of formats and images, you can create a test sequence to automate the process of selecting formats and images. Test sequences provide a way to progress through a pre-defined sequence of format and images, either manually or automatically.
Creating a test sequence You can create a test sequence using the command line interface, the generator’s built-in editor or VGM. Creating a test sequence using command line You can develop test sequences either by entering command interactively through a terminal session or by entering a series of commands in a text file and then send them to the generator through hyper terminal.

Control Description Move Use the Format knob to select the file you want to move, press Move, then use the Format knob to specify the target location, and then press Move again. Delete Removes the selected sequence file from the sequence list. Insert Inserts the sequence file selected from the list of available files into the sequence list. Remove Deletes the sequence file selected in the list of available files from non-volatile memory.
Viewing the test sequence list You can view the list of test sequences stored in the generator using the command line interface, the internal sequence editor or VGM. Viewing the test sequence list using the command line Use the following procedure to view the test sequence list using the command line interface. To view the sequence list using the command line interface: 1. Establish a terminal session with the generator. 2.
Viewing test sequence using internal sequence editor Use the following procedure to view the test sequence list using the internal sequence editor. To view the sequence list using the internal sequence editor: 1. Hold down the Image key while starting the generator, until programmer is displayed. 2. Select the SeqList image. 3. Press the Image key to start the Sequence List editor. The Sequence List box shows a list of sequence files that can be selected with the Format knob.
Running a sequence Regardless of how you created a test sequence you can initiate it through the command line, the built-in editor or VGM. For information on running a test sequence through VGM refer to the VGM help. The instructions for running test sequences through the command line or internal sequence editor are provided below.
To run a sequence in automatic mode: 1. Establish a terminal session with the generator. 2. Enter the following commands: SEQL MySeq SMOD 3 SEQU // loads MySeq into sequence edit buffer // sets the sequence mode to run in auto mode // starts running the MySeq sequence 3. To stop the sequence, hold down the ACS, DCS, and DSS keys, and then cycle the power to the generator. To run a sequence at power up: 1. Run the sequence in the desired mode. 2. Turn off the power to the generator. 3.
3. Depending on the mode of the sequence, the sequence will start automatically, or you need to turn the Image knob to move forward and backward though the sequence. The LCD will display the format and image name for each step, and the current step number. Additional status information may appear before the step number, depending on the mode (manual, automatic, wrap).
7 Using GPIB Interface Topics in this chapter: • Overview • Setting the GPIB port address • Queries and commands • Status queries and control 802BT/802R Video Test Generator User Guide 97
Overview You can operate and program the 802 generator from an external computer or terminal using either the RS-232C serial port or optional IEEE-488 (GPIB) port. The GPIB port enables the 802 to be used as a programmable video signal source for integration into automated test systems that use IEEE-488 or GPIB communications between instruments.
Setting the GPIB port address The default GPIB address is 15. You can specify a different address. To set the address of the GPIB port directly on the generator: 1. Locate the rotary switches on the back of the generator between the RS-232 port and the GPIB port. These are accessible through the ventilation slots. There are two rotary switches: the one on the left configures the value of the tens digit and the one on the right configures the value of the ones digit. 2.
Queries and commands The GPIB interface is an ASCII command line interface like the RS-232 command line interface. The communications protocol is per IEEE-488.2 specification. Queries and commands consist of four ASCII upper/lower case characters. Commands do not require a response from the generator, while queries cause the 802 to respond with the required data. You can send multiple commands on the same line by separating the commands with a semicolon (;) followed by a terminator.
For example, the following number can be represented in three ways: • Integer (42) • Floating point (42.00) • Scaled floating point (4.200E+01) Queries Queries are comprised of a header followed immediately by a question mark (?). If there are any characters between the query header and the question mark character (including whitespace), a command error will result. Queries, return a response message upon completion of execution.
Sending commands and queries The generator parses command lines one at a time. Command lines must be terminated with a carriage return ().The generator immediately echoes each character as it is received and places it in a command line buffer. This buffer currently has room for a total of 256 characters.
to wait for all preceding commands to be completed before the commands that follow *WAI are processed. For example, sending the following command line causes a red rectangle to be drawn and then overwritten by the colorbar image. IMGL COLORBAR; IMGU; IMGE; RECT RED 200 200 0 0 GRAYPAT100 Note that the IMGU command merely requests that the current image be rendered eventually, not necessarily right away nor in a single attempt.
Status queries and control To create applications that control the generator using the GPIB port, it is sometimes necessary to query the status of the generator and set or reset the status bits and bytes. There are two sets of status registers: 1) the Event Status Register and Event Status Enable Register and 2) the Status Byte Register and Service Request Enable Register. These are described in the following paragraphs.
4 Operation Complete 5 Request Control Execution Error 6 Device Dependent Error Command Error 7 Query Error Power On User Request The following figure illustrates IEEE-488 status reporting.
Event Status bit Definition OPC Operation complete. Indicates that all operations have been completed. RQC Request control. Indicates that a device is requesting control. The generator will never request control, so this bit will always be 0. QYE Query error. Indicates that a query request was made while the generator was in deadlock. DDE Device dependent error. Indicates that the generator encountered an error executing a command. EXE Execution error.
In the remote with lockout state (RWLS), the generator is under complete remote control and front panel controls are disabled. The generator enters the RWLS state when the controller issues the local lockout (LLO) message to the generator. Front panel access is re-enabled when the controller issues the go to local (GTL) message to the generator. In the local state (LOCS), the generator is under local control and all front panel controls are enabled.

10 Testing EDID Topics in this chapter: • Overview • EDID testing for source devices • EDID testing for sink devices 802BT/802R Video Test Generator User Guide 165
Overview This chapter provides procedures for testing EDID generation and handling. The generator can be configured to emulate an HDMI/DVI source when testing HDMI/DVI sink (display) devices or it can be configured to emulate an HDMI/DVI sink (display) device when testing an HDMI/DVI source device. Some of the EDID tests require the analyzer option. These include testing the EDID handling capabilities of a source device and the HDMI compliance EDID testing for a sink (display) device.
EDID testing for source devices The generator can emulate an HDMI/DVI sink (display) in order to test HDMI source devices. Testing response of source to EDID The analyzer can emulate different HDMI/DVI displays using a built-in, configurable EDID structure. With this capability an HDMI/DVI source device can be tested for its ability to handle an EDID structure received from virtually any DDC-compatible display.
5. Release the Step, G, and B keys to enable status display on the generator (see example below). Color space Color depth Video type H31 V60 Format name D8C=DMT0659 0=SMPTE133 Image version Image name The format status on the LCD will indicate whether the unit is outputting HDMI or DVI signal protocol from the Tx connector. An “H” in the format status (H8C in the example above) indicates HDMI output; a “D” in the format status indicates DVI output.
4. Using the Image knob, select the ON setting to enable analyzer images. 5. Using the Format knob, select the Auto Based On field. 6. Using the Image knob, select CURRENT in the highlighted field to measure the HDMI/DVI signal originating internally from the generator. 7. Press and release the Step key to save the currently displayed parameters. The light on the Step key extinguishes, and the new settings are implemented for analyzer mode operation.
To test the source device’s handling of the EDID: 1. Connect the HDMI/DVI source device to the HDMI/DVI Rx connector on the generator. Upon receiving the HDMI/DVI signal at the HDMI/DVI Rx connector, the generator sends the EDID structure to the source device. 2. At the HDMI/DVI source device, compare the processed EDID information with the EDID structure defined in the generator.
EDID testing for sink devices The generator can emulate an HDMI, DVI or VGA source device in order to test HDMI, DVI or VGA displays. This includes viewing EDID from a display and writing EDID data to a display. The generator can test an HDMI display device’s EDID structure and transmission in accordance with the HDMI Compliance Test Specification 1.0. Viewing EDID from a display You can use the generator to view EDID from a DDC-compliant VGA, HDMI or DVI display connected with the generator.
5. To view parsed EDID information, press and release the Step key, and then turn the Image knob to view additional blocks and parsed data. To query EDID information from an HDMI, DVI or VGA display via the command line: 1. Using a terminal emulator, establish a terminal session with the generator (see page 14). 2. To view the current EDID in ASCII hex format, use the EDID? command. To view a specific segment of EDID, use the I2CR? command.
3. Use the I2CW command to modify the EDID structure in the connected display. For example, to change the color characteristics of the EDID structure (a total of 10 bytes starting at byte 19), you could use the following command string: i2cw eprom1 a0 25 A E88A82A0564796240F48 4. To program multiple segments or a complete EDID structure, use a text editor to enter the commands in a text file, and then download the file to the generator from a terminal emulator program such as HyperTerminal.
Testing HDMI sink devices for EDID compliance The procedures for EDID and video testing of HDMI sink devices in accordance with the HDMI Compliance Test Specification 1.0 are provided below. Note: The EDID and video tests should be performed in sequence as a single test series. Each test is dependent on successful completion of the previous test. To set up the generator for HDMI compliance testing: 1. Hold down the G and B keys, and then power on the generator.
To specify the capabilities of the sink device: 1. Load the CDF_Sink image, which is shown below. 2. Press and release the Step key to enable selection of each field. Use the Format knob to position the cursor. Use the Image knob to choose values. For example, if your display supports both 4:3 and 16:9 aspect ratios, set the Sink_PrimaryAR field to Both. 3. Press the Step (Exit) key to save the settings. The settings are stored until you change them, and are kept if the generator is restarted.
Testing EDID readability (Test ID 8-1) - This test verifies that the EDID can be read properly. The screens are shown below.

11 Testing HDCP You can use the generator, with the High-bandwidth Digital Content Protection (HDCP) option installed, to test HDCP 1.0 and 1.1 compliant devices. For more information about HDCP, see http://www.digital-cp.com/.
Testing DVI or HDMI receiver with HDCP This section describes how to test DVI and HDMI receivers with HDCP. All DVI and HDMI options, including analyzer options, support HDCP production keys if the HDCP option is installed. Some DVI options support both production and public keys. To determine which HDCP keys your generator supports: 1. Load the GenStats image. 2. Verify that HDCP is listed under the Options heading, which indicates that the HDCP option is installed, and that production keys are available.
• HdcpA2B The image will indicate if the test passed or failed. If the test fails, see “Troubleshooting HDCP errors” on page 191. 4. To test another device, connect the cable to the new device. The HDCP test starts automatically. To test HDCP with an HDMI device: 1. Hold down the G and B key while starting the generator put the generator in digital friendly mode. Alternatively, enter the following command: SROP 2 2. Connect the HDMI transmitter on the generator to the device’s HDMI receiver. 3.
Testing HDCP between HDMI transmitter and DVI receiver HDCP 1.1-compliant devices must interoperate with HDCP 1.0 compliant devices using the DVI protocol. Generators with an HDMI transmitter can be used to test HDCP with devices that have an DVI receiver. To test HDMI Tx with DVI Rx: 1. Hold down the G and B key while starting the generator put the generator in digital friendly mode. Alternatively, enter the following command: SROP 2 2.
Testing HDCP with static images The standard HDCP test images have color bars in the background. A special mode is available for testing HDCP with any static background image you specify. To test HDCP with a different background image: 1. Turn on the generator while holding down the G and ACS keys until hdcp tester is displayed. Alternatively, enter the following command: SROP 8192 2. Select a format that is supported by the display, and then load any static image.
Using command-line interface to control HDCP The command interface can control HDCP tests in automated testing environments. To run HDCP test from command prompt: 1. Establish a command terminal connection with the generator using VGM or HyperTerminal. 2. Connect the device to be tested to the transmitter on the generator. 3. At the R:> prompt, enter the following command to run the HDCP test: HDCP? HDCP? command The HDCP? command is the only command used to control HDCP tests.
Troubleshooting HDCP errors Common problems This table describes possible solutions to problems that may occur during HDCP testing. Problem Solution Test fails at step 3 Transmitter could not read Bksv from the receiver, Bksv was read correctly but is a wrong value, or an I2C error occurred. If the EdidData image loads, the I2C communication is working properly. Verify that the Bksv value is 5 bytes (that is, 40 bits of which 20 zeros and 20 ones) by reading the value from the test image.
To run an HDCP self-test: 1. Hold down the G and B key while starting the generator put the generator in digital friendly mode. Alternatively, enter the following command: SROP 2 2. Connect your cable to the Rx and Tx on the analyzer. 3. Select the HdcpProd image. When testing a display, the HDCP test results are displayed on the display being tested. When testing a cable, where no display is connected to the transmitter, test results are displayed by the LCD display on the generator.
2. If the “Reset HDCP Rx by gating clock” mode is enabled, the generator resets the receiver, and gates off transmitter clock and data for 400 mS. Otherwise, the receiver is not reset. 3. The transmitter reads the Bksv (HDCP receiver KSV), over the I2C bus, and verifies that it has 20 zeros and 20 ones. This step is the first interaction between the transmitter and receiver. 4. Receiver writes the receiver KSV to the transmitter. 5. Transmitter generates An (session random number). 6.

12 Using Special Sync Output Topics in this chapter: • Operating special sync for probe pulse • Configuring special sync for FS, LS or CS 802BT/802R Video Test Generator User Guide 195
Overview The generator is equipped with a Special Sync BNC connector labeled S/S on the front right side. You can configure the output of this video interface to output frame sync, line sync, composite sync or a special probe pulse.
Operating special sync for probe pulse The probe feature is used in connection with a programmable probe pulse that is available on the S/S BNC. This pulse is most often used to trigger an oscilloscope or synchronize an inspection camera. The probe feature allows you to position the leading edge of the probe pulse anywhere within the video frame. This feature greatly facilitates troubleshooting by enabling you to focus on specific video signal problems occurring anywhere in the video signal.
Configuring the probe feature This section describes how to configure the probe feature. To enable the probe feature: 1. Deactivate the signal outputs of the generator by pressing the Outputs key. The light on the Outputs key extinguishes. 2. Hold down the Step key, and then press and release the Outputs key. The LCD displays a Probe feature message, and then the following screen. 3. Release the Step key.
between the start of active video (X:0) and the leading edge of the probe pulse in the horizontal direction. 2. Set the vertical position by turning the Image knob. The vertical position of the probe is simultaneously displayed in two different ways: • The vertical position L:nnnn is given in whole scan lines relative to the leading edge of blanking of the frame or first field.
PSHD edge PSVD edge ALLU 100 // set pulse horizontal position at 100 pixels from leading of horiztonal sync pulse, in range from 0 <= PSHD<(HTOT - PSPW - 1) 50 // set the pulse vertical position at 50 lines from leadinig of vertical blanking, in range from 0<=PSVD<(VTOT-1) // apply the settings To set the lines on which the probe pulse occurs: 1. Send the appropriate command: Set the probe pulse to occur Command Once per frame PSPM 0 Once every active line PSPM 1 Once every line PSPM 3 2.
Configuring special sync for FS, LS or CS The special sync output can provide frame sync, line sync, or composite sync signals. The output is controlled by setting parameters of these signals through the command line interface. The following commands are used to set the special sync signal: • FSPG - Frame sync • PSPG - Probe signal • LSPG - Line sync • CSPG - Composite sync Note: The special sync output is disabled whenever these parameters are set to zero.
3. Set the frame pulse pixel width (in the range from 1 pixel to HTOT - 1) by entering the following command: FSPW 100 4. Set the frame pulse delay (in the range from 0 <= FSPD < (VTOT - FSPW - 1) [default = 0]) by entering the following command: FSPD 10 5. Save these settings by entering the following command: ALLU To configure line sync on the special sync output: 1.

In the Outline2 version, the two diagonal lines are removed and short marker lines are added to the corners, and where cross lines meet and end. In the Outline3 version, the two diagonal lines are removed, cross lines are shortened, and short marker lines are added. Test Purpose Method Yoke tilt correction The horizontal axis of a displayed image should line up with the horizontal axis of your monitor. Any tilt is likely due to the yoke being rotated on the neck of the CRT.
specification for the monitor. If it is out of specification, the yoke must be adjusted. Loosen the hardware that clamps the yoke to the neck of the CRT and rotate the yoke until the line is horizontal. Tighten the yoke-clamp hardware. Test Purpose Method Test Yoke winding orthogonality check The horizontal and vertical deflection coils on the yoke should have their axes cross at exactly 90 degrees.
Method Measure the lengths of the two (2) diagonal lines. Any difference is an indication of parallelogram distortion. The difference in readings should be within the specifications of the monitor. If the difference in the readings is too far beyond specification, the monitor should be rejected and sent back for repair, rather than trying to magnet a defective yoke. Test Trapezoid distortion correction Purpose This image gives you a way to measure trapezoid distortion in your monitor.
There are two main ways of correcting pincushion distortion. The first involves placing or adjusting magnets on the yoke. This is a trial-and-error method. However, skilled operators develop a feel for how strong a magnet to use and how to place it in order to get the desired correction. If any correction is performed, the trapezoid distortion correction should be repeated. The other correction method involves adding correction signals to the deflection signal driving the yoke.

used in many different display applications. The image is self-scaling as to the number of active pixels and active lines used. Some of the image’s elements have minor differences from the original SMPTE specification. These differences are noted in descriptions of the individual elements. • The image is drawn on a reference background having a 50% intensity level. The background covers the entire active video area. • Crosshatch – There are 10 boxes vertically.
100% with two (2) boxes at a 50% level. All of the grayscale boxes are omitted in the secondary version. • Gamma check dither box – A small box is drawn inside the right-hand 50% grayscale box. The box is half the width and height of the larger box. The box consists of a checkerboard of alternate one-on and one-off pixels. The alternate pixels have levels of 0 and 100%. This smaller box is not part of the original SMPTE specification and is omitted in the secondary version.
Test Method Test Method Test Method Test Method Test Method Test Method Test Method Test High contrast resolution All the 0 and 100% level stripes in all the resolution patches should be separate and distinct. Low contrast resolution and noise All the mid-level 2 on - 2 off stripes in all the resolution patches should be visible and distinct. This is a sensitive test for noise in the display’s video amplifiers.
Method The horizontal 1 on - 1 off stripes in the resolution boxes should not have objectionable flicker when shown with an interlaced format. Excessive flicker indicates that the combination of the display’s CRT persistence and frame scan rate is below the persistence time of the human eye. SMPTEbar Description This image is based on an engineering guideline (EG1-1990) test signal specified by the Society of Motion Picture and Television Engineers (SMPTE).
• Test The remaining central 8% of the image contains a row of chroma set bars. These bars are part of the SMPTE pattern but are not in the EIA pattern. The order of the alternating color and black bars matches those in the SMPTE pattern. Color video performance Purpose This general purpose pattern can be used to check the video handling capabilities of most parts of a television system. Method When viewed on a TV screen, all of the upper color bars should be correct and in the order shown.
Test Method Visual chroma gain adjustment To perform this test, you must have a way of turning off the red and green guns in the monitor under test. Turning off the red and green video components of the 801GX generator’s video output will not work for this test. This test uses the upper and central color bars. Switch off the red and green guns on the monitor. This will produce four blue bars, separated by black bars.

System errors This section discusses system error messages that may be displayed by the generator from time to time. Power-on self test messages The integrity of the data stored in non-volatile memory is checked every time the generator is turned on. The following tests are performed: 1. The system configuration memory is checked. The memory remembers what the generator was doing when it was last powered down.
custom image or test sequence) that are corrupted. It is up to the user to check the contents of the individual items. Attempting to load a corrupted item will report and error for that item. A corrupted format can be repaired be either editing it or by downloading a new set of data from a computer. In most cases, a corrupted custom image or test sequence can not be repaired. This is due to the variable data structure used. You will need to recreate and save the data back into memory.
Format errors Under normal operating conditions, a properly programmed model 801GX generator should never report any Format error messages. If you do get an error message while loading a format it is for one of two reasons. The generator distinguishes between invalid data, entered in one of the programming modes, and corrupted data caused by a memory failure. In either case, the generator will shut all of its outputs off. The outputs remain off until a valid format is loaded.
