GPIB Address Assignments

Figure 3- 1 describes how GPIB addresses should be assigned for sending pass- thru commands. These are the same addresses used in Example 3- 1.

Pass Thru

17

The pass thru address is automatically selected by the 8757D by inverting

 

 

the last bit of the 8757D address. Refer to the 8757D documentation for

 

 

more information. Verify that no other instrument is using this address

 

 

on the GPIB bus.

 

 

 

Example Pass-Thru Program

Example 3- 1 on page 99 is a sample Agilent BASIC program that switches the 8757D to pass- thru mode, allowing you to send operating commands to the PSG. After the program runs, control is given back to the network analyzer. The following describes the command lines used in the program.

Line 30

PT is set to equal the source address. C1 is added, but not needed, to specify the

 

channel.

Lines 40, 90

The END statement is required to complete the language transition.

Lines 50, 100

A WAIT statement is recommended after a language change to allow all instrument

 

changes to be completed before the next command.

Lines 70, 80

This is added to ensure that the instrument has completed all operations before

 

switching languages. Lines 70 and 80 can only be used when the signal generator

 

is in single sweep mode.

Line 110

This takes the network analyzer out of pass- thru command mode, and puts it back

 

in control. Any analyzer command can now be entered.

NOTE Verify the signal generator is in single sweep mode. Refer to the SCPI Reference or the User’s Guide, as required.
