ICalData Interface for putting and getting typed Calibration data.
The Calibrator object, a child of the channel, is used to perform an Unguided calibration.
|
Important! Do NOT use commands from the GuidedCalibration object when performing an Unguided calibration. Use ONLY the Calibrator object. You can NOT perform a full 3 or 4-port using the Calibrator object. You must use the GuidedCalibration object. |
There must be a measurement present for the calibrator to use or you will receive a "no measurement found" error. Therefore, to perform a 2-port cal, you must have any S-parameter measurement on the channel. For a 1-port measurement, you must have the measurement (S11 or S22) on the channel. The same is true for a response measurement.
There are a number of approaches to calibration with the calibrator object:
You can collect data yourself and download it to the ACQUISITION buffer. The acquisition buffer holds the actual measured data for each standard. See the VNA data map.
Calibrator.SetCalInfo
Connect a standard
Trigger a sweep
Retrieve the data for the standard
Download the data - calibrator.putStandard
Repeat for each standard
Calibrator.CalculateErrorCoefficients
You can tell the calibrator to acquire a standard. In this case, the calibrator collects the data and places it in the ACQUISITION buffer.
Calibrator.SetCalInfo
Connect a standard
Calibrator.AcquireCalStandard2
Repeat for each standard
Calibrator.CalcuateErrorCoefficients
You can put previously-retrieved error terms in the error correction buffer.
Repeat for each term
Measurement.Caltype = pick one
You can also "piece together" a 2-port cal from two 1-port cals (S11 and S22) and four response (thru) cals. The system will detect that all the standards needed for a 2-port cal have been acquired even though they may not have gathered at the same time.
Dim app As AgilentPNA835x.Application
Set app = CreateObject("AgilentPNA835x.Application", <analyzerName>)
Dim cal As ICalibrator
Set cal = app.ActiveChannel.Calibrator

Contains methods for putting Calibration data in and getting Calibration data out of the analyzer using typed data. This interface transfers data more efficiently than variant data. However, this interfaces is only usable from VB6, C, & C++. All other programming languages must use the ICalSet interface.
There is also an ICalData Interface on the CalSet Object
