About Source Power Cal

Description

This command replaces AcquirePowerReadings Method

Initiates a source power cal acquisition.

 VB Syntax

powerCalibrator.AcquirePowerReadingsEx calMethod, acqdevice [,sync]

Variable

(Type) - Description

powerCalibrator

(object) - A SourcePowerCalibrator object

calMethod

(enum NASourcePowerCalMethod)  Selects the calibration method to be used for the source power cal acquisition.

0 – naPowerMeter  Use power meter for all readings.

1 - naPowerMeterAndReceiver  Power meter for the first iteration; then use the reference receiver for remaining readings if necessary.

2 - naReceiver  Use VNA measurement receiver for all readings.

acqdevice

(String) The specific acquisition device to be used.  NOT case sensitive. Choose from:

If calMethod = naPowerMeter or naPowerMeterAndReceiver, choose from:

• “ASEN” -- Sensor on power meter channel A.

• “BSEN” -- Sensor on power meter channel B.

• To use the sensor that currently corresponds to the frequency of interest, use the value from the PowerAcquisitionDevice property.

If calMethod = naReceiver, choose from:

• The receiver names for your specific VNA using either physical receiver notation or logical receiver notation. For example, ”a1” or "A".

• Any configured PMAR device name. Learn more about PMAR Devices. See PMAR commands

[sync]

(boolean) Optional argument. If not specified, value is set to False.  Choose from:

True (1) – The method does not return until this acquisition has completed (the program calling this method is halted while waiting for the method to return).

False (0) – The method initiates an acquisition then returns immediately (while the acquisition still proceeds).  The program calling this method can then perform other operations during the acquisition.

Return Type

None

Default

Not Applicable

Examples
