CAUTION As an antistatic precaution, do not touch exposed connector contacts!

Information about installing, performing an operational check, and verifying the main antenna measurement system is explained in the appropriate documentation listed below:

• Agilent 85301B Antenna Measurement System Manual

• Agilent 85301C Antenna Measurement System Manual

• Agilent 85310A Distributed Frequency Converter Manual

If you purchased an Agilent 8511 as a stand-alone unit, refer to the Agilent 8530A On-Site Service Manual for installation instructions. Verify the 8511

as explained in its operating and service manual.

Choosing the Proper Conﬁguration

Installing the Agilent 85330A Multiple Channel

Controller

There are two ways to install the Agilent 85330A system. Figure 1-1 on

page 1-3 is a ﬂow chart that shows a installation conﬁguration that is

appropriate for you to use.

How to use the ﬁgure

Follow the ﬂow chart from the top. Determine if your measurements are made with a single frequency (CW), or multiple frequencies. Proceed down the appropriate ﬂow chart path. Proceed in this way until you get to a box that recommends either Figure 1-2 on page 1-4, or Figure 1-3 on page 1-5.

Fast Source Control

Fast source control speeds up frequency switching speed in multiple-frequency measurements. It is only available in systems that use two Agilent 836xx series synthesized sources. This mode uses TTL signals to increment RF and LO source frequency, providing faster frequency switching speeds than are possible under 8530A control. In the fast source control conﬁguration, the system’s computer must set up the sources with appropriate frequency settings, triggering mode, and so on. When automatic Run Time measurement mode is engaged, the 85330A automatically increments the RF and LO source frequencies using TTL lines. More information is provided in Chapter 6, “Programming.” When the sources are controlled by a computer, the SCPI language mode must be selected. This is shown in Figure 1-3 on page 1-5.

Select an instrument._ SYSTEM 85330A IBASIC

NOTE IBASIC is only present if the IBASIC option is installed.

If the display shows loaded.

If you do not see this display, load the VXI mainframe downloadable driver ﬁles as explained in “Loading the Driver from a Personal Computer,” next.

The 85330A contains 85330A driver ﬁles from the disk labeled 85330A Downloadable Driver Disk. When your system was shipped, the driver ﬁles were already loaded into the non-volatile memory of the 85330A mainframe. Once loaded, it will remain when the mainframe is powered down or when the power is interrupted to the mainframe.

If you must reload the drivers, a complete set of instructions are included in the

INSTALL.TXT ﬁle on the supplied driver disk, or perform the following

instructions:

NOTE This method uses a personal computer (PC) to download the drivers over a

serial cable (supplied).

(see note below)

“DIG I/O” instead of “85330A”, then the drivers are no longer

NOTE The downloadable driver disk should not be set to the write-protected

position or the driver ﬁles will not load properly.

Checking Operation of the Multiple Channel Controller

NOTE You can use other com ports, such as com2. However, you have to edit a ﬁle

called

“VXIDLD.CFG” so the software knows you are using a different port.

This conﬁguration ﬁle can be edited with any ASCII text editor, such as notepad. Save the changed ﬁle back to the supplied disk.

NOTE Agilent recommends that you make two backups of the driver disk. Make

one copy to a ﬂoppy disk, and one copy to the personal computer used with the system.

Procedure

NOTE This procedure may not work on later versions of Microsoft®1 Windows®

such as Windows NT® and Windows 2000®.

1. Disconnect any GPIB cables from the mainframe. If it is easier, you can

disconnect the GPIB from the back of the system controller computer.

2. Turn the VXI mainframe ON.

3. On your PC, open a DOS command prompt window.

4. Insert the supplied driver disk into drive A. (Do not write-protect the

downloadable driver disk. The driver will not load if the write-protect

window is open. Make sure the tab is snapped fully into the closed

portion.)

5. In the DOS command prompt window, change to drive A.

6. In the DOS command prompt window, type

VXIDLD and press [Enter].

7. The mainframe download procedure takes approximately six or seven

minutes, and the mainframe will reboot.

NOTE There are several error messages that can be ignored. These are described in

the README.TXT ﬁle on the driver disk. Speciﬁcally, refer to the description of the VXIDLD.CFG ﬁle.

8. Reconnect all the GPIB cables.

9. When ﬁnished, the following should be displayed:

channel controller to the SCU. Make sure the 85384A switch drive cable is long enough to reach from the SCU to the switch.

Changing any of the DIP switches inside the SCU is not recommended. All switch settings are made at the factory.

In a standard system (deﬁned below), the following settings are used:

• SCU address is set to 0.

• Channel numbers 1 through 4 are used to select switch positions.

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 number assignments (1 through 4) for

both switch modules. Since each SCU is on a different port, and each port is addressed independently, there is not a channel number conﬂict.

Performance Verification

2 Performance Veriﬁcation

In This Chapter • Recommended performance veriﬁcation test equipment

• Performance veriﬁcation tests

• Verifying the multiple channel controller

• Verifying the RF switches

Description This performance veriﬁcation should be done once a year, or more

frequently as needed. This procedure veriﬁes that the Agilent 85330A system meets or exceeds its published speciﬁcations. Speciﬁcations are listed in Chapter 4, “General Information.”If traceability to a local standards organization is required, then it can be done with this procedure. One such standards organization is the United States National Institute of Standards and Technology (NIST, formerly NBS).

This veriﬁcation can be performed at the measurement system’s site, or at a service bench. The veriﬁcation will verify all parts of the multiple channel system: multiple channel controller, switches, and cables. This veriﬁcation does not check the performance of the measurement system’s transmitter or receiver. Use the measurement system’s manual for more information on that procedure.

General Information

Product Description The Agilent 85330A multiple channel controller adds high-speed

multiple-channel measurement capability to Agilent 8530A-based automated measurement systems, using high-isolation solid state microwave switch modules. The 85330A is a run time controller that orchestrates the sequencing and synchronizing of all the required functions for multiple-channel and multiple-frequency measurements, to allow very fast data acquisition speed and data throughput of the measurement system.

This provides an additional manual. To obtain this item after receiving the 85330A, order part number 85330-90019.

In-depth Information Measurement Speed Advantages

The multiple channel controller, when used with the Autoranged Fast Data Acquisition mode, provides very fast measurement speeds. Even faster measurements can be made when the RF/LO sources are controlled using the direct TTL source control capabilities of the multiple channel controller.

Frequency states can be downloaded to the Agilent 8360 series of frequency synthesizers. The multiple channel controller sends TTL triggers to the sources (in two-source systems) at the appropriate time to change their frequency. This method maximizes the frequency agility of the system by allowing the sources to switch at their fastest rate.

Triggering

The 85330A receives triggers from the positioning system, and synchronizes the data acquisition to the positioning system. It also controls the triggering of the microwave receiver, and sequencing of the multiple channel data into the receiver.

Lowering the Workload on the Computer Controller

When using 85330A as the system controller, the demands of the computer are decreased during run-time. The computer is free to collect data from the receiver and perform data manipulation, display, and storage.

4-2 85330A Multiple Channel Controller

Installing the Detachable Power Cord

Install the instrument so that the detachable power cord is readily identiﬁable and is easily reached by the operator.The detachable power cord is the instrument disconnecting device. It disconnects the mains circuits from the mains supply. The front panel switch is only a standby switch and is not a LINE switch. Alternatively, an externally installed switch or circuit breaker (which is readily identiﬁable and is easily reached by the operator) may be used as a disconnective device.

Manual Operation Front panel softkeys allow you to:

• View or change the 85330A’s GPIB address.

• Close any switch in the system (select a channel).

• Change the TTL state of AUX 1 or AUX 2.

• View the revision of the downloaded driver.

General Information

• Perform service functions.

Refer to Chapter 5, “Manual Operation,” for more information.

Automated Operation During automated operation, the 85330A can control switches in two ways:

Direct Control The 85330A can directly control switch states

and issue triggers using GPIB commands.

Run Time Mode Using GPIB commands, the 85330A

can be set up for a speciﬁc measurement sequence, then automatically execute that measurement (run-time mode).

85330A Multiple Channel Controller 4-3

General Information

Preparing the 85330A to Control the System

Conﬁguring the 85330A is composed of the following steps:

1. Send the 85330A a series of GPIB setup commands prior to starting the run-time sequence.

2. Start the run-time sequence by sending a speciﬁc GPIB command.

3. The 85330A then waits for a positioner trigger signal to begin the sequence.

4. The 85330A repeats the sequence for the speciﬁed number of frequency points to be measured.

More detailed information on this subject is explained in Chapter 6,

“Programming.”

Special Systems Special system conﬁgurations allow you to:

• Daisy-chain SCUs to provide many channels with a single multiple

channel controller.

• Add remote multiple channel controllers to expand the switch tree or

extend the physical distance that switches can be placed from the control room. Additional remote multiple channel controllers can be up to 2 Kilometers away from the master.

Switch Components The 85330A controls the following items:

Switch control units

In standard systems, the system interface board communicates with one or two SCUs. SCUs perform the following tasks:

• They decode binary information from the multiple channel controller to

determine which switch should be closed.

• They provide the necessary bias voltages to the switches, which causes

them to switch states.

In a standard system, one SCU is connected to the multiple channel controller’sPORT 1 connector, and the other SCU is connected to PORT2. The separate ports provide the ability to put switches at the transmit and receive site.

EVENT TRIG

By default, this input accepts a positive or negative-edge TTL trigger from the positioner controller or other device. The default is positive-edge triggering. The trigger signal initiates a measurement sequence. Connect EVENT TRIG to the positioner controller or other TTL trigger source.

You can conﬁgure the 85330A so it responds to a negative-edge TTL trigger signal. Refer to Chapter 1, “Installation,” for instructions.

MEAS BUSY

Goes TTL HIGH when the EVENT TRIG line is asserted. This line stays HIGH during the measurement sequence, going LOW after the measurement sequence is ﬁnished. This line is designed to tell external control logic when the measurement system is busy, and using it is optional.

RCVR TRIG

Sends a 2 to 3 µs negative-edge pulse to the EVENT TRIGGER input of the receiver. This causes the receiver to acquire data. The number of parameters measured by a single trigger pulse is determined by how the receiver measurement controls are set up. A single parameter (radioed measurement point) is taken in the FASC, FASD, FASAD (Fast Data Acquisition) modes, and multiple parameters are measured if you are using the FASMUX mode.

General Information

Rear Panel Features

The multiple channel controller may send several receiver trigger pulses during the measurement sequence, depending on the instructions you sent to it before starting the run-time mode.

RCVR READY

This positive-edge signal is sent by the receiver when it ﬁnished acquiring data. This line connects to the RECEIVER READY line on the receiver.

AUX 1

Provides a user-controllable TTL line for special applications. The state of AUX 1 must be set before entering the 85330A’s automatic run-time mode. The state of AUX 1 is controlled with the ROUTe:CONTrol command.

AUX 2

Provides a user-controllable TTL line for special applications. The state of AUX 2 can be set in two ways:

• Before entering run-time mode using the ROUTe:CLOSe command.

• During run-time using RUNTime:SWITch:SCAN command.

SRC 1 TRIG

Used in conjunction with SRC 1 READY, controls frequency switching in the RF source much faster than is possible under 8530A control.This connects to the TRIGGER IN line of the RF source.

SRC 1 READY

Used in conjunction with SRC 1 TRIG, controls frequency switching in the RF source much faster than is possible under 8530A control. This connects to the TRIGGER OUT line of the RF source.

SRC 2 TRIG

Used in conjunction with SRC 2 READY, controls frequency switching in the LO source much faster than is possible under 8530A control. This connects to the TRIGGER IN line of the LO source.

SRC 2 READY

Used in conjunction with SRC 2 TRIG, controls frequency switching in the LO source much faster than is possible under 8530A control. This connects to the TRIGGER OUT line of the LO source.

4. Enter the switch address using the numeric keypad. In a standard system, simply enter the channel number (1, 2, 3, or 4), and press

[Return].

The “switch address” is a concatenation of the Switch Control Unit (SCU) address (set to 0 at the factory) with the channel number (in “standard” systems this number is 1, 2, 3, or 4).

If you just enter the channel number (1, 2, 3, or 4), the multiple channel controller will assume that the SCU address is still at the factory default (0). Changing SCU address requires DIP switch changes inside the SCU, and is not necessary in standard systems. To select switch 1 (channel 1), just press

[1] [Return].

In custom systems with many switches, a different SCU address might be used in part of the switch tree. Here are some example switch addresses for complex switch trees:

101 (SCU address 1, channel 01) 212 (SCU address 2, channel 12) 312 (SCU address 3, channel 12)

Notice in the ﬁrst example (101) that a two digit channel number (01) was required. When the SCU address is set to 1, 2 or 3, you must enter a two-digit channel number – even for channels 1 through 9.

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.

• GPIB addresses

• Deﬁnition of terms

• To choose a measurement conﬁguration

• To use Direct control

• To use run-time control mode

• Programming examples

GPIB Addresses Using GPIB commands, the 85330A can be set up prior to run-time followed

by an GPIB command to pass run-time control to the 85330A. This is called run-time control mode. The 85330A can also directly control switch states and issue triggers using GPIB commands. This is called direct control.

Long and Short Command Syntax

BASIC is used for all examples. To address the 85330A, a secondary GPIB address is needed. In most cases the complete GPIB address would be 70918:

• “7” refers to the select code of the GPIB address.

• “09” is the GPIB address of the 85330A multiple channel controller.

• “18” is the secondary address of the E1330A/B DIO card. This is a

board that is inside the multiple channel controller.

The GPIB commands have a long and short form. The upper-case characters represent the short form and the complete set of characters represent the long form. Example, ROUTe:CLOSe is the complete or long from of the GPIB command while the abbreviated or short form is ROUT:CLOS.

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. For custom-designed systems, refer to the documentation that came with that system for SCU address numbers. Daisy-chained SCUs may use the same SCU address.

Channel

Each switch module has either two or four possible switch positions, or channels. If you purchased a switching system designed by Agilent, you also have received a manual that applies speciﬁcally to that switch tree. That document shows the channel numbers for each switch. If you have purchased a “standard” system, then channels 1 through 4 are the factory default channel numbers. (Channels 3 and 4 only apply to four-throw switches.)

NOTE Ports 1 and 2 are addressed independently. Because of this, there are no

addressing conﬂicts when using two SCUs—even if they use the same SCU address and channel numbers.

Switch address

This is the complete software address for a speciﬁc switch. It is simply a concatenation of the SCU address (0, 1, 2, or 3) with the channel number (usually 1, 2, 3, or 4, but possibly a number up to 64 in custom systems).

Examples: @103 = SCU address 1 and channel 3 selected. @2 = SCU address is 0 (and need not be speciﬁed), and channel 2 is

selected. @232 = SCU address is 2 and channel 32 is selected (custom systems only). The port number (1 or 2) is speciﬁed separately, as is explained later in this

chapter.

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. Determine if your measurements are made with a single frequency (CW) or multiple frequencies. Proceed down the appropriate ﬂow chart path. Proceed in this way until you get to a box that mentions one of the following headings:

• CW Measurement Conﬁguration

• Single Source Multiple-Frequency Conﬁguration

• 8530A Control of Sources

• Fast Source Control

Proceed to the section indicated to read about that speciﬁc conﬁguration.

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.

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.

Refer to the programming “Example 2” on page 6-25.

• Select multiple parameter display mode on the 8530A. The number of

parameters selected should equal the number of test signals you are measuring. For example, assume you have a two-throw receive switch connected to two test signals. In this case, program the 8530A for two parameter display GPIB command pressing

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 command is described in the Stimulus chapter of the Agilent 8530A

Operating and Programming Manual.

• Set the 8530A so it waits for a trigger before measuring each parameter.

Programming

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.

8530A Control of Sources

Description If you choose to control source frequency switching with the 8530A (and

you are using the dual source multiple-frequency conﬁguration), you cannot use the Fast Data Acquisition modes of the receiver. Refer to the programming “Example 2” on page 6-25.

To Use this Conﬁguration

Operation in this mode is nearly identical to that described in “Single Source

Multiple-Frequency Conﬁguration” on page 6-5. When the sources are

under 8530A control, the multiple channel controller must be set to the IMMediate triggering mode:

RUNT:SOUR:SOURCE1:TRIG IMM; RUNT:SOUR:SOURCE2:TRIG IMM;

Use GPIB address 19 for the RF source, and 18 for the LO source.

85330A Multiple Channel Controller 6-7

Programming

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.

To Use this Conﬁguration

In the fast source control conﬁguration, the system’s computer must set up the sources with appropriate frequency settings, triggering mode, and so on. When automatic run-time measurement mode is engaged, the 85330A automatically increments the RF and LO source frequencies using TTL lines. When being controlled by a computer, the SCPI language mode must be selected. This is shown in Figure 1-3 on page 1-5.

Fast Data Acquisition can be used in this conﬁguration. Use the 8530A Fast Autoranging Data Mode (GPIB command: of the Agilent 8530A User’s Guide.

FASAD),as explained in Chapter 8

8530A settings

In the 8530A Local menu, the addresses for Source 1 and Source 2 must be set to 31. This tells the 8530A that it cannot communicate with the sources.

85330A settings

Since the 8530A does not control the sources, set the multiple channel controller to TTL triggering mode:

RUNT:SOUR:SOURCE1:TRIG TTL; RUNT:SOUR:SOURCE2:TRIG TTL;

Source settings

• Use Frequency List or Step mode.

• Sweep Point Trigger must be set to EXT:

SWE:TRIG:SOUR EXT;

• Start Sweep Trigger must be set to AUTO:

TRIG:SOUR IMM;

The Sweep Point Trigger and Start Sweep Trigger settings allow external triggers from the 85330A to trigger the sources.

closed, all other channels on that module are open. For example, when 1 is closed, 2, 3 and 4 are open; when 2 is closed, 1, 3, and 4 are open.

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 operation. Figure 6-2 on page 6-16 is a ﬂow chart that illustrates the run-time measurement sequence. Commands are described in Chapter 7,

“Remote Programming Command Reference.”

Event Triggering During run-time operation, the 85330A may use two different types of event

triggering, TTL or IMM. Most angle scan measurements will be set up for TTL triggering, while TTL triggering can be suppressed for a frequency response measurement, typically at a single angle. Also, this IMM mode combined with the information of a multiple-frequency, multi-parameter measurement.

*OPC? command is useful for determining timing

Number of Frequency Points

Number of Angular Increments (Events)

Applicable command:

The 85330A does not require a start, stop, or frequency step size. In fact, it does not require any frequency values. It only needs to know the number of frequency points so it can issue the correct number of triggers.

Applicable command:

The 85330A does not require any angular values. It only requires the number of angular increments so it can issue the correct number of triggers.

Applicable command: RUNTime:EVENt:COUNt

RUNTime:EVENte:TRIGger

RUNTime:SOURce:COUNt

List of Switch States One must set up the list of channel addresses for the measurement. For each

event trigger received by the 85330A, each channel address entry will be asserted and a subsequent trigger issued to begin a measurement of each data point.

Applicable command:

RUNTime:SWITch:SCAN

Switch Settling Time You must specify switch settling time before starting run-time mode. The

default setting is 2

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:

µs.

• The single source multiple-frequency conﬁguration.

• The dual source multiple-frequency conﬁguration, but only when the

8530A controls the sources.

TTL Trigger and Ready Timeouts

Applicable command:

Timeout conditions are used for:

RUNTime:SWITch:DELay

• Event triggering (EVENT TRIG)

• Receiver ready (RCVR READY)

• Source ready lines (SRC 1 READY and SRC 2 READY)

Timeouts enable the 85330A to recover from possible error conditions. The timeout for the event trigger input has two separate timeout settings:

• One timeout is for the ﬁrst trigger being issued.

• The other timeout is for subsequent triggers.

If the expected signal is not received before the speciﬁed time, the 85330A will exit from run-time operation and issue an error.

Applicable commands:

• RUNTime:TIMEout:EVENt

• RUNTime:TIMEout:RECeiver

• RUNTime:TIMEout:SOURce

85330A Multiple Channel Controller 6-13

Programming

To Use Run-Time Control Mode

Using More than One Controller

Starting Run-Time Mode

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.

To set up and control the remote controller, use these commands:

• RUNTime:CONTroller

• RUNTime:TIMEout:REMote

• RUNTime:SWITch:TRIGger

The remote controllers can be triggered using the commands:

• RUNTime:SOURce:SOURCE1:TRIGger

• RUNTime:SOURce:SOURCE2:TRIGger

Issue the RUNT:INIT:IMM command to initiate the run-time operation. This command passes the hardware control to the 85330A and allows it to accept and issue triggers.

OUTPUT 70918;"RUNT:INIT:IMM;”

Once the sequence is initiated the 85330A either:

Run-Time Measurement Sequence

• Waits for an event trigger before issuing a trigger to the receiver,

OR:

• Immediately issues a trigger to the receiver.

This is set using the

Refer to Figure 6-2, “Run-Time Flow Chart with Programming Command

References,” on page 6-16. The chart shows the sequence of a run-time

measurement. Programming commands applicable to each function are shown. All programming commands must be executed before run-time is initiated. Here is a description of the run-time measurement sequence:

Idle

This is the idle state of the 85330A. This also the state the unit enters if an error occurs during run-time. Run-time mode is started when executed.

Select Switch State

The ﬁrst switch state is selected for Port 1 or Port 2, as deﬁned with the

RUNT:SWIT:SCAN command. A delay now occurs to allow the switch to settle,

deﬁned with

RUNT:SWIT:DEL.

RUNT:EVEN:TRIG command.

RUNT:INIT:IMM is

6-14 85330A Multiple Channel Controller

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.

Receiver Ready

The 85330A now waits for the Receiver Ready signal (from the receiver), indicating that the 8530A is ready to take another measurement. If a timeout occurs while waiting for Receiver Ready, run-time is aborted and an error message is issued. The timeout duration can be set using the

RUNT:TIME:REC

command.

Switch List Loop

If all switch settings deﬁned in RUNT:SWIT:SCAN have not been measured, the next switch state is asserted and the settling time delay occurs. Another measurement trigger is sent to the receiver, and the 85330A waits for Receiver Ready again. This loop continues until all deﬁned switch states have been measured.

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.

• If source 1 triggering is set to TTL (applicable for fast source control

mode), a frequency-incrementing trigger is sent to source 1, and the 85330A waits for the TTL Ready signal before continuing. If a timeout occurs while waiting for TTL Ready, run-time is aborted and an error message is issued. The timeout duration can be set using the

RUNT:TIME:SOUR command. When TTL Ready is received, the 85330A

checks the triggering mode of source 2. If source 1 triggering is set to IMM (applicable for measurements where

the sources are controlled by the 8530A), the 85330A immediately checks the triggering mode of source 2.

• If source 2 triggering is set to TTL (applicable for fast source control

mode), a frequency-incrementing trigger is sent to source 2, and the 85330A waits for the TTL Ready signal before continuing. If a timeout occurs while waiting for TTL Ready, run-time is aborted and an error message is issued. The timeout duration can be set using the 85330A

RUNT:TIME:SOUR command. When TTL Ready is received, the 85330A

re-enters the Switch List Loop so all switch states will be measured at the new frequency.

If source 2 triggering is set to IMM (applicable to measurements where the sources are controlled by the 8530A), the 85330A immediately re-enters the Switch List Loop so all switch states will be measured at the new frequency.

Event Loop

Once all switch states have been measured at all frequencies, the next “event” can be measured. This would be the next angle in an antenna measurement system. Stated generically, this is a full repetition of measurements at all switch states and frequencies for the next “event.” An “event” being whatever has occurred that caused another Event Trigger signal. The number of events in the measurement is deﬁned using the

RUNT:EVEN:COUN command.

The sequence now loops back to START EVENT, which is at the beginning of the eventloop. The event loop repeats, measuring all switch states at each frequency until the number of event loops is completed. When ﬁnished, the 85330A exits run-time mode and goes into the idle state.

Run-Time Measurement Sequence for Multiple Controllers

Using IMM vs. TTL Trigger for Source 1

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.

Refer to “Source 1 IMM, TTL or REM1 trigger diamond in Figure 6-3. When using multi frequencies:

• The RF Source controlled by the master 85330A should use the TTL

trigger.

• The other RF Source (not controlled by the master 85330A) should use

the IMM trigger.
