Controlling the Test Set
U
sing Test Set I/O Commands
A Test Set I/O command may be used when the PNA is connected to the Test
Set via the Test Set I/O cable. Commands may control the test set or read data
from the test set. The GPIB command processor utility, in the network analyzer
software, is used to communicate over the Test Set I/O connector.
It is recommended to use a USB keyboard with a PNA when using the
command processor.
Using the GPIB C ommand P rocessor
— Select Utility > System > Configure > SICL/GPIB/SCPI, then GPIB Command
Processor Console. In the dialog box type the command text and then Enter
on the keyboard to execute the command.
— A write command is of the form: cont:ext:test:data n,m "n" is the address
and "m" is the data to be written. Typically these values may be any number
up to three digits in length.
— A read command is of the form: cont:ext:test:data? n "n" is the address. A
read command returns a single numeric value.
— Pressing F3 on the keyboard will recall a previously sent command line for
editing.
— As a check, send the command: cont:ext:test:data? 0 <enter>. A 61 or 62
should be returned, depending on the model number of the test set.
— An active command processor window may be minimized via the "_" in the
upper right hand corner of the window. To access a minimized command
processor window, minimize the PNA window. Select File > Minimize
Application.
