Description
This object is a child of the Application object and is a vehicle for performing source power calibrations.
Dim app As AgilentPNA835x.Application
Set app = CreateObject("AgilentPNA835x.Application", <analyzerName>)
Dim ispc As ISourcePowerCalibrator
Set ispc = app.SourcePowerCalibrator
|
Note: If you see this error: The target NA stimulus channel has not been set. With the SourcePowerCalibrator object, you must first call SetCalInfoEx with the channel number. SetCalInfoEx must not be made against a temporary copy of the SourcePowerCalibrator object. Or this error: Channel not found. It is either because you set the wrong channel number in the SetCalInfoEx call or because the SourcePowerCalibrator object is unique in that you MUST use the SAME instance of the SourcePowerCalibrator object for every property that is set. Do this by naming/setting a variable as in this vbs example: set sourcepowercalibrator = app.sourcepowercalibrator |
Note: Interface ISourcePowerCalibrator is abbreviated as ISPC in the following table.
