Programming 6 Programming In This Chapter This chapter provides a general programing of the operation for the Agilent 85330A and a detailed description of the programming codes. Several scenarios and examples are given.
Programming Definition of Terms NOTE Please review the following terms before reading information in this chapter. SCU address At the factory, each Switch Control Unit is assigned an address called an SCU address. When commands are sent out port 1 or port 2, they only affect SCUs with the specified SCU address. SCU addresses are set using DIP switches inside the SCU, and can be set to 0, 1, 2, or 3. In a standard system, the factory default setting is 0.
Programming To Choose a Measurement Configuration To Choose a Measurement Configuration The measurement configuration you use depends on the type of measurement (CW or multiple-frequency) and the type of system (one-source or two-source system). One-source systems use the Agilent 8511A/B frequency converter, two-source systems use the Agilent 85309A frequency converter. Refer to Figure 6-1. How to Use the Figure Follow the flow chart from the top.
Programming CW Measurement Configuration CW Measurement Configuration Description In single-frequency measurements, the Fast Source Control mode is not used. The RF source (and LO source, if used) can either be controlled by: • • The 8530A (set the sources to Analyzer Language mode), or... The system computer (set the sources to SCPI Language mode). Refer to the programming “Example 1” on page 6-21. To Use this Configuration The proper setup is shown in Figure 1-2 on page 1-4.
Programming Single Source Multiple-Frequency Configuration Single Source Multiple-Frequency Configuration Description In single-source (8511A/B based) systems, the Fast Source Control mode is not available. The RF source is controlled by the 8530A (Analyzer Language mode). The proper setup is shown in Figure 1-2 on page 1-4. The Fast Data Acquisition modes of the 8530A cannot be used with this type of measurement. Instead, the multiple parameter display of the 8530A is used to measure each switch input.
Programming Single Source Multiple-Frequency Configuration This setup allows the 8530A to measure each receive switch input in sequence. Each one is measured as a separate parameter, which you can read using the system computer. Refer to the GPIB Programming chapter of the Agilent 8530A Operating and Programming Manual for detailed information. • Select external triggering with TRGEXT. This is equivalent to pressing STIMULUS {MENU} {MORE} {TRIGGER MODE} {TRIG SRC EXTERNAL}.
Programming Dual Source Multiple-Frequency Measurements Dual Source Multiple-Frequency Measurements When you are using multiple-frequency measurements with an 85309A frequency converter, you can choose how the sources are controlled: • • You can allow the 8530A to control source frequency switching, or... You can use the Fast Source Control configuration, where source frequency switching is controlled by the multiple channel controller.
Programming Fast Source Control Fast Source Control Description Fast source control speeds up frequency switching speed in multiple-frequency measurements. It is only available in 85309A-based systems. This mode uses TTL signals to increment RF and LO source frequency, providing faster frequency switching speeds than are possible under 8530A control. Refer to the programming “Example 3” on page 6-29.
Programming To Use Direct Control To Use Direct Control Direct control is where the host computer issues GPIB commands and the 85330A executes them immediately. For example, the ROUTe:CLOSe (port number) (switch address) command causes the 85330A to immediately change switch states. Selecting a Channel Here are examples of how to select a channel. Example 1, for a standard system OUTPUT 70918; “ROUT:CLOS 1,(@2);” Switch port 1, default SCU address (0), channel 2 selected.
Programming To Use Direct Control Other examples: OUTPUT 70918;”ROUT:CLOS 2,(@103);” Switch Port 2, SCU address 1, channel 3. OUTPUT 70918;”ROUT:CLOS 1,(@2);” Switch Port 1, SCU address 0, channel 2. OUTPUT 70918,”ROUT:CLOS 1,(@132);” Switch Port 1, SCU address 1, channel 32. Sending multiple switch addresses is possible. In the following example: • • An example is provided for standard systems (SCU address 0). An example is provided for a typical custom system, with an SCU address of 1.
Programming To Use Direct Control In this example: • • • The 85330A is reset using the *RST command. A delay between switch states is specified. Channels 101, 102, 103 and 104 are selected in sequence.
Programming To Use Run-Time Control Mode To Use Run-Time Control Mode Setup of the 85330A Multiple Channel Controller The setup for run-time operation includes setting: • • • • • • • The event triggering method The number of frequency points The number of angular increments List of switch states Switch settling time TTL trigger and ready timeouts Using more than one controller Once the 85330A is set up, send the RUNT:INIT:IMM command to begin run-time operation.
Programming To Use Run-Time Control Mode Switch Settling Time You must specify switch settling time before starting run-time mode. The default setting is 2 µs. NOTE If your configuration requires you to use the multiple-parameter display features of the 8530A, as described in “Single Source Multiple-Frequency Configuration” on page 6-5, set settling time to 50 µs. This applies to: • • The single source multiple-frequency configuration.
Programming To Use Run-Time Control Mode Using More than One Controller More than one multiple channel controller may be used in a system. Multiple controllers are usually used when the distance to a switch control unit exceeds the maximum length allowed. The REMOTE 1 and REMOTE 2 connectors on the rear panel allow connections to multiple controllers. See Chapter 9, “Service” for more information on these connectors.
Programming To Use Run-Time Control Mode Event Trigger If TTL triggering has been selected, the 85330A waits for an Event Trigger pulse before sending a measurement trigger to the receiver. If IMM triggering has been selected, the measurement trigger is sent to the receiver immediately. The trigger mode is selected using RUNT:EVEN:TRIG. If a timeout occurs while waiting for Event Trigger, run-time is aborted and an error message is issued. The timeout duration can be set using the RUNT:TIME:EVEN command.

Programming To Use Run-Time Control Mode Frequency Loop After all switch states have been measured at the first frequency, the measurements can now be repeated at the next frequency. Here are the steps that occur during the frequency change: • The first switch state is asserted once more, and the settling time delay occurs.
Programming To Use Run-Time Control Mode Run-Time Measurement Sequence for Multiple Controllers The run-time measurement sequence for multiple controllers is similar to a single controller shown earlier. See “Starting Run-Time Mode” on page 6-14 for more information on this sequence. The sequence for multiple controllers has additional steps to allow communications between the controllers. Refer to Figure 6-3 on page 6-19 and Figure 6-4 on page 6-20 for the actual run-time measurement sequence.

Remote Programming Command Reference Standard Command Reference RUNTime:CONTroller This command sets the multiple channel controller as the master CONTroller or the REMote1 or REMote2 controller. When the multiple channel controller is INITiated to the RUNTime mode, the controller will execute a sequence based on its CONTroller status. Default Default is CONTroller. Syntax RUNT:CONT CONT | REM1 | REM2; Example RUNT:CONT CONT; NOTE (This command is in revision A.02.31 or greater.
Remote Programming Command Reference Standard Command Reference RUNTime:EVENt:TRIGger The event trigger source allows either TTL triggering to control the run-time sequencing or IMMediate triggering to occur. TTL Mode In TTL mode, the run-time control will: 1. Wait for an event trigger. 2. When the event trigger occurs, run-time control asserts each switch address entry in the scan list (one at a time), issuing a measurement trigger to the receiver for each. 3.
Remote Programming Command Reference Standard Command Reference RUNTime:INITiate:IMM Initiates the run-time sequence and control of a measurement. All parameters must be set up prior to initiating RUNT:INIT:IMM. Once the measurement is initiated, it will run until completion or until a timeout has occurred. If a timeout does occur, it will report the error to the error stack. Default The event trigger is defaulted to TTL. See other related commands for their defaults.
Remote Programming Command Reference Standard Command Reference RUNTime:SOURce:SOURCE1:TRIGger Selects IMM, TTL, REMote1, or REMote2 triggering for source 1 (the RF source). Default The default trigger mode is TTL. Syntax RUNTime:SOURce:SOURCE1:TRIGger IMM | TTL | REMote1 | REMote2; Example RUNT:SOUR:SOURCE1:TRIG IMM; NOTE In the fast source stepping mode (also known as Turbo), the trigger is set to TTL.
Remote Programming Command Reference Standard Command Reference RUNTime:SWITch:DELay Used for the delay between asserting the switch address list entry of the RUNT:SWIT:SCAN command and the issuance of a receiver trigger. The input to the command is in microseconds. Default The default is 2 microseconds. Syntax RUNT:SWIT:DEL ; Example RUNT:SWIT:DEL 50; ! Set the trigger or setting ! time to 50 micro-seconds.
Remote Programming Command Reference Standard Command Reference RUNTime:SWITch:SCAN Set up the list of channel addresses for run-time control. For each event increment signal received by the 85330A, each channel address entry will be asserted and a subsequent trigger issued to begin a measurement of each data point. This command can also be used to set the TTL level of the rear panel AUX 2 connector during run-time mode. Default Scan list for port 1 and port 2 are empty.
Remote Programming Command Reference Standard Command Reference RUNTime:SWITch:TRIGger The switch trigger source allows either TTL triggering from the REMote controller to control the run-time sequencing or IMMeadiate triggering to occur. Default The default trigger mode is IMM. Syntax RUNT:SWIT:TRIG IMM | TTL; Example RUNT:SWIT:TRIG TTL; NOTE This command is in revision A.02.31 or greater.
Remote Programming Command Reference Standard Command Reference RUNTime:TIMEout:EVENt A timeout setting for event triggers during run-time. The timeout for the event trigger input has separate timeouts: • One prior to the first trigger being issued: RUNT:TIME:EVEN 0, time in µs • The other for all subsequent triggers: RUNT:TIME:EVEN 1, time in µs Default The default for the first trigger is 15 seconds (15000000 microseconds) and for subsequent triggers is 10 seconds (10000000 microseconds).
Remote Programming Command Reference Standard Command Reference RUNTime:TIMEout:REMote Allows a timeout to occur if the REMote1 or REMote2 controller does not respond in determined time. Default The default is 1 second (1000000 microseconds). Syntax RUNT:TIME:REM ; Example RUNT:TIME:REM 1000000; NOTE This command is in revision A.02.31 or greater. RUNTime:TIMEout:SOURce Allows a timeout to occur if the source 1 or source 2 ready line does not respond in determined time.

Service Theory of Operation Theory of Operation The 85330A multiple channel controller was designed as a high-speed, real-time controller for the 8530A microwave receiver. The 85330A controls external solid-state transmit and receive switches and allows for asynchronous TTL communications to the receiver, the RF and LO sources, and other remote 85330As.
GPIB
Service Theory of Operation The 85330-60002 card contains the TTL trigger and ready lines that interface to the 8530A microwave receiver, the RF source, and the LO source. The communication to the switch control unit is through sets of parallel twisted-pair wires and bias wires. These wires enable placement of the switches next to the transmit and receive devices. This minimizes the RF path lengths to the external mixer modules and therefore decreases the amount of RF losses.

The internal power supply is used when there is few SCUs and RF switches.
Service Preventive Maintenance Preventive Maintenance Preventive maintenance for the multiple channel controller consists of cleaning various parts of the mainframe. The switch control unit and switches do not require preventive maintenance. Agilent recommends a twelve month interval between cleaning. However, cleaning intervals are mostly dependent upon where the mainframe is used. The mainframe should be cleaned more often if it is used in a dusty, or very humid area.

Accessory Documentation 10-2 85330A Multiple Channel Controller
Glossary A Glossary a1 The reference IF channel of the 8530A. This channel can be used as a phase lock reference or a test channel. a2 The test IF channel of the 8530A. This channel can be used as a phase lock reference or a test channel. AUT Antenna Under Test b1 One of three test channels of the 8530A. b2 One of three test channels of the 8530A. Channel Each switch module has either two or four possible switch positions, or channels.
Glossary Fast Data Acquisition Modes Fast Data Acquisition modes (also called “Fast CW” modes) refer to a set of similar 8530A measurement modes where: • All data processing except averaging is suspended to provide fastest possible measurement speed. • All data is stored in a 100,000 point FIFO data buffer, which can be read by a computer controller. As mentioned above, these modes are also referred to as the “Fast CW” modes.
Glossary Insertion Loss A transmission measurement determines how much RF energy is lost as it passes through the device under test (DUT). Energy loss is measured in units called “insertion loss” and is measured in dB units. It is important to be aware of transmission losses in the system so you will not attribute them to the antenna or device under test. For example: If you send 0 dBm down a cable with 10 dB of insertion loss, −10 dBm will come out the other end.
Glossary Receiver System All of the instruments in the system that act as the RF downconverter and IF receiver. Remote 1 The mode a 85330 operates in when it is being controlled by another 85330A in the Controller mode. Refer to “RUNTime: CONTroller” command and Chapter 6, “Programming” for more information. Remote 2 The mode a 85330 operates in when it is being controlled by another 85330A in the Controller mode.
Glossary Standard System A “standard system” uses one 85330A with one or two switch control units, each with a two-throw or four-throw switch module. Remember that 85330A PORT 1 and PORT 2 are addressed independently. So: • • If you have two SCUs, both can use the default SCU address (0). You can use the default channel numbers (1 through 4) for both switch modules. Since each SCU is on a different port, and each port is addressed independently, there is no channel number conflict.
