How to run this program:

The SCPI commands in this example are sent over a COM interface using the SCPIStringParser object. You do NOT need a GPIB connection to run this example.

This VBScript (*.vbs) program can be run as a macro in the analyzer. To do this, copy the following code into a text editor file such as Notepad and save it on the analyzer hard drive as NewMeas.vbs. Learn how to setup and run the macro.

Dim app

Dim scpi

' Create / Get the PNA application.

Set app = CreateObject("AgilentPNA835x.Application")

Set scpi = app.ScpiStringParser

'Preset the analyzer

'This command also deletes the default trace

scpi.execute "SYSTem:FPReset"

'Create Measurements

scpi.execute "CALCulate1:PARameter:DEFine:EXT 'Meas1','S11'"

scpi.execute "CALCulate2:PARameter:DEFine:EXT 'Meas2','S21'"

' Turn on windows - creates if new

scpi.execute "DISPlay:WINDow1:STATE ON"

scpi.execute "DISPlay:WINDow2:STATE ON"

'Associate ("FEED") the measurement name('Meas1') to WINDow(1), and give the new TRACe a number(1).

scpi.execute "DISPlay:WINDow1:TRACe1:FEED 'Meas1'"

scpi.execute "DISPlay:WINDow2:TRACe2:FEED 'Meas2'"

'Change each channel's frequency range

scpi.execute "SENSe1:FREQuency:SPAN 1e9"

scpi.execute "SENSe2:FREQuency:SPAN 2e9"

'Select both measurements

scpi.execute "CALCulate1:PARameter:SELect 'Meas1'"

scpi.execute "CALCulate2:PARameter:SELect 'Meas2'"

'Turn marker 1 ON for each measurement

scpi.execute "CALCulate1:MARKer:STATe ON"

scpi.execute "CALCulate2:MARKer:STATE ON"
