QPHY-10GBase-KR Operator’s Manual Introduction About QualiPHY QualiPHY is highly automated compliance test software meant to help you develop and validate the PHY (physical-electrical) layer of a device, in accordance with the official documents published by the applicable standards organizations and special interest groups (SIGs). You can additionally set custom variables and limits to test compliance to internal standards.
Required Host Computer System Usually, the oscilloscope is the host computer for the QualiPHY software, and all models that meet the acquisition requirements will also meet the host system requirements.
QPHY-10GBase-KR Operator’s Manual Installation and Setup QualiPHY is a Windows-based application that can be configured with one or more serial data compliance components. Each compliance component is purchased as a software option. Install Base Application Download the latest version of the QualiPHY software from: teledynelecroy.
Set Up Remote Control QualiPHY software can be executed from a remote host computer, controlling the oscilloscope through a LAN Connection. To set up remote control: • The oscilloscope must be connected to a LAN and assigned an IP address (fixed or dynamic). • The host computer must be on the same LAN as the oscilloscope. Note: LXI, GPIB, LSIB, and USBTMC remote control is available for some model instruments.
QPHY-10GBase-KR Operator’s Manual Using QualiPHY This section provides an overview of the QualiPHY user interface and general procedures. For detailed information about the QPHY-10GBase-KR software option, see QPHY-10GBase-KR Testing. Accessing the Software Once QualiPHY is installed and activated, it can be accessed from the oscilloscope menu bar by choosing Analysis > QualiPHY, or by double-clicking the QualiPHY desktop icon on a remote computer.
General Setup The first sub-dialog contains general system settings. These remain in effect for each session, regardless of Standard, until changed. Connection tab Shows IP Address of the test oscilloscope (local host 127.0.0.1 if QualiPHY is run from the oscilloscope). The Scope Selector allows you to choose the oscilloscope used for testing when several are connected to the QualiPHY installation. See Set Up Remote Control for details.
QPHY-10GBase-KR Operator’s Manual QualiPHY Test Process Once general system settings are in place, these are the steps for running test sessions. Set Up Test Session 1. Connect the oscilloscope to the DUT. See QPHY-10GBase-KR Testing Physical Setup. 2. Access the QualiPHY software to display the framework dialog. 3. If running QualiPHY remotely, click General Setup and open the Scope Selector to select the correct oscilloscope connection. 4.
Run Tests 1. On the framework dialog, click Start to begin testing. When tests are in progress, this button changes to Stop. Click it at any time to stop the test in process. You’ll be able to resume from the point of termination or from the beginning of the test. 2. Follow the pop-up window prompts. QualiPHY guides you step-by-step through each of the tests described in the standard specification, including diagrams of the connection to the DUT for each required test mode. 3.
QPHY-10GBase-KR Operator’s Manual Run Reports The QualiPHY software automates report generation. On the framework dialog, go to General Setup > Report to pre-configure reporting behavior. You can also manually launch the Report Generator from the framework dialog once a test is run. The Report Generator offers the same selections as the Report tab, only applied to each report individually, rather than as a system setting.
Customizing QualiPHY The pre-loaded configurations cannot be modified. However, you can create your own test configurations by copying one of the standard test configurations and modifying it. Copy Configuration 1. Access the QualiPHY framework dialog and select a Standard. 2. Click Edit/View Configuration and select the configuration upon which to base the new configuration. This can be a pre-loaded configuration or another copy. 3. Click Copy and enter a name and description.
QPHY-10GBase-KR Operator’s Manual Edit Variables The Variable Setup tab contains a list of test variables. See QPHY-10GBase-KR Variables for a description of each. To modify a variable: 1. Select the variable on the Variable Setup tab, then click Edit Variable. (You can also choose to Reset to Default at any time.) 2. The conditions of this variable appear on a pop-up. Choose the new condition to apply. Figure 3 - Variable Setup tab.
Edit Test Limits The Limits tab shows the Limit Set currently associated with the configuration. Any limit set can be associated with a custom configuration by selecting it in this field. The Limits Manager shows the settings for every test limit in a limit set. Those in the default set are the limits defined by the standard. To create a custom limit set: 1. On the Limits tab, click Limits Manager. 2. With the default set selected, click Copy Set and enter a name.
QPHY-10GBase-KR Operator’s Manual X-Replay Mode The X-Replay mode window is an advanced (“developer”) view of QualiPHY. The tree in the upper-left frame enables you to navigate to processes in the 10GBase-KR test script, in case you need to review the code, which appears in the upper-right frame. Two other particularly useful features are: • A list of recent test sessions in the lower-left frame.
QPHY-10GBase-KR Testing Test Preparation Before beginning any test or data acquisition, the oscilloscope should be warmed for at least 20 minutes. Calibration is automatic under software control and no manual calibration is required. This procedure will be run again if the temperature of the oscilloscope changes by more than a few degrees. QPHY-10GBase-KR Test Configurations Test configurations include variable settings, limit sets, and test selections.
QPHY-10GBase-KR Operator’s Manual QPHY-10GBase-KR Test Descriptions These are the standard 10GBase-KR compliance tests. Jitter: Tj, Rj, Dj, DCD & BitRate This test measures all timing parameters that can be measured on a PRBS or scrambled data signal. The measurements are directly produced by SDAII or SDAIII. Voltage Measurements Single Ended – on 0101 This test measures MaxDiffPPOutVoltage, MaxCommonMode and MinCommonMode, and DutyCycle. MaxCommonMode is 1.9V. The MinDiffCommonMode limit is -0.
QPHY-10GBase-KR Variables ACQUIRE LIVE DATA This variable allows the user to acquire live data signals instead of using stored waveform files. DEMO MODE When this value is to “On”, the tests are run in demonstration mode using saved waveforms. The waveforms are recalled into memory automatically. (Note that the waveforms are stored internally in the QPHY-10GBASE-KR script file). The default value for this variable is “Off”.
QPHY-10GBase-KR Operator’s Manual Specific to Jitter and Voltage Tests TEST PATTERN FOR JITTER Choose the pattern to use for jitter measurements. Patterns 1 and 2 are short enough to treat as a repeating pattern. Pattern 3, PRBS-31, is treated as a non-repeating pattern. Default is Pattern 1 or 2. QPHY-10GBase-KR Limit Sets The default installation of QPHY-10GBase-KR contains only one test limit set, called “Default.” In this script, limits are only used to convey Unit labels.
Manual Deskewing Procedures This section is only applicable to the oscilloscope and the cables connecting to the oscilloscope channels. Cable Deskewing Using the Fast Edge Output The following procedure demonstrates how to manually deskew two oscilloscope channels and cables using the fast edge output, with no need for any T connector or adapters. Note: Fast Edge output is available only on some models.
QPHY-10GBase-KR Operator’s Manual • Trigger i. Configure to Source to be FastEdge. ii. Set the Slope to Positive. • Parameter Measurements: i. Set the source for P1 to CX and the measure to Delay. ii. Set the source for P2 to CY and the measure to Delay. iii. Set the source for P3 to M1 and the measure to Delay. 3. Set the display to Single Grid. • Click Display Single Grid. 4. Using the appropriate adapter, connect Channel X to the Fast Edge Output of the oscilloscope. 5.
10. Save Channel X to M1. • Click File Save Waveform. • Set Save To Memory. • Set the Source to CX. • Set the Destination to M1. • Click Save Now. 11. Disconnect Channel X from the Fast Edge Output and connect Channel Y to the Fast Edge Output. 12. Press the Clear Sweeps button on the front panel to reset the averaging. 13. Allow multiple acquisitions to occur until the waveform is stable on the screen. 14.
QPHY-10GBase-KR Operator’s Manual Cable Deskewing Without Using the Fast Edge Output The following procedure demonstrates how to manually deskew two oscilloscope channels and cables using the differential data signal, with no need for any T connector or adapters. This can be done once the temperature of the oscilloscope is stable. The oscilloscope must be warmed up for at least a half-hour before proceeding.
In the previous procedure, we used the default setup of the Skew parameter (which is detecting positive edges on both signals at 50%). We also inverted C2 in order to make C1 and C2 both have positive edges at the same time. Alternately, we clearly could have not inverted C2 and instead selected the Skew clock 2 tab in the P1 parameter menu and set the oscilloscope to look for negative edges on the second input (C2).
QPHY-10GBase-KR Operator’s Manual Error Messages These messages may appear when using QualiPHY. “Warning, no valid technology package has been found…” This message appears if none of the QualiPHY components have been activated on the oscilloscope before launching the QualiPHY application. See Activate Components.
