Perform a Guided QSOLT Cal

This example performs a Guided QSOLT calibration on a 4-port PNA.

Because the DUT port 1 is female and the other ports are male, a 'Zero Thru' can be used between port 1 and the other ports. If this were NOT the case, a "Defined Thru" would be needed in the listed Cal Kits for those ports. Learn more about Thru methods.

Although no standards are used for ports 2, 3, and 4, a Cal Kit must be defined for these ports.

The SCPI commands in this example are sent over a COM interface using the SCPIStringParser object. You do not need to control the PNA via GPIB to run this example.

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

' Initiate the calibration and query the number of steps

scpi.Execute "sens1:corr:coll:guid:init"

numSteps = scpi.Execute("sens:corr:coll:guid:steps?")

MsgBox "Number of steps is " + CStr(numSteps)

' Measure the standards

For i = 1 To numSteps

step = "Step " + CStr(i) + " of " + CStr(numSteps)

strPrompt = scpi.Execute("sens:corr:coll:guid:desc? " + CStr(i))

MsgBox strPrompt, vbOKOnly, step

scpi.Execute "sens:corr:coll:guid:acq STAN" + CStr(i)


' Conclude the calibration
