Perform an SMC Phase Reference Cal

This example sets Phase Reference Cal properties, then performs a Phase Reference calibration.

It is NOT necessary to create an SMC measurement before performing a remote Phase Reference Cal. It is necessary when performed from the user interface.

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 PMAR.vbs. Learn how to setup and run the macro.

Example Program: performs a phase reference calibration between 1Ghz to 10Ghz on Ports 1, 2, and 4.

Set app = CreateObject("agilentpna835x.application")

app.preset

app.activechannel.hold 1

Set PhaseReferenceCal = app.GetCalManager().PhaseReferenceCalibration

' always call reset at the beginning of your cal

PhaseReferenceCal.Reset

PhaseReferenceCal.StartFrequency = 1e9

PhaseReferenceCal.StopFrequency = 10e9

' Read serial numbers of connected phase references

' Into variant array

refs = PhaseReferenceCal.GetConnectedPhaseReferences

'Change the following to your own phase reference name

PhaseReferenceCal.PhaseReference = "MYPILOT44"

PhaseReferenceCal.SourceAttenuator = 10

PhaseReferenceCal.Calset = "Remote Phase Reference"

PhaseReferenceCal.ConnectorType = "APC 3.5 female"

PhaseReferenceCal.CalKitType = "85052D"

' Perform the calibration on Port 4 (Port 1 and Port 2 are always included)

PhaseReferenceCal.IncludePort(4) = true

' Uncomment the following line to use an unknown mixer

' to extend the phase reference cal down to 10 Mhz

' If an unknown mixer is used, then the start frequency is always 10 Mhz

' PhaseReferenceCal.IncludeUnknownMixer = true

Set guidedCal = PhaseReferenceCal.GuidedCalibration

Steps = guidedCal.GenerateSteps

for i = 1 to steps

Msgbox guidedCal.GetStepDescription(i)

guidedCal.AcquireStep i

next

msgbox guidedCal.GenerateErrorTerms

msgbox "done"
