External Testset Control

The following VB Script example exercises the COM commands used to control the Z5623AK64 testset.

For a description of each command, see TestsetControl Object

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

' Demonstrate some COM commands for external testsets.

Dim pna

Set pna = CreateObject("AgilentPNA835x.Application")

Sub DemoTestset(na)

Dim testsets, tset1

Dim portNum

Dim chNum, address

Set testsets = na.ExternalTestsets

chNum = 1

' Load a configuration file.

' NOTE: the K64 testset is only compatible with 4-port analyzers.

address = 0

testsets.Add "Z5623AK64", address

' Get the testset object

' in the testsets collection.

Set tset1 = testsets(1)

' Show the selections available for each port.

For portNum = 1 To 4

MsgBox("Port " & CStr(portNum) & " catalog: " & tset1.PortCatalog(portNum))

' Set port mappings on channel 1.

tset1.OutputPorts(chNum) = "5 ext R,2 int R,3 int R,6 int R"

' Set control lines.

tset1.ControlLines(chNum) = 85

' Set label.

tset1.Label(chNum) = "Some label"

' Enable external testset control. This automatically enables status bar display as well.

tset1.Enabled = True

End Sub

' The testset used in this demo is only usable on 4-port analyzers

If (pna.NumberOfPorts <> 4) Then

MsgBox("This program only runs on 4-port analyzers.")

Else
