Methods

	Name	Description
	AbortMeasurements	Stops acquisition and measurements associated with signal instance that you specify in the selectorString parameter, which were previously initiated by the Initiate(String, String) or measurement read methods. Calling this method is optional, unless you want to stop a measurement before it is complete. This method executes even if there is an incoming error.
	BuildCalibrationElementString	Creates a selector string specifying the Calibration Element within the Calkit.
	BuildCalkitString	Creates a selector string specifying the Calkit.
	BuildCalstepString	Creates the calibration step string to use as the selector string with the CalibrationAcquire(String, Double) method.
	BuildConnectorString	Creates a selector string specifying the Connector within the Calkit.
	BuildPortString	Creates selector string specifying the port(s) for use with configuration or fetch methods and methods.
	BuildPulseGeneratorString	Creates the selector string specifying the Pulse Generator for use with configuration or fetch properties.
	BuildResultString	Creates selector string for use with configuration or fetch.
	BuildSegmentString	Creates a selector string specifying the segment number for use with configuration or fetch methods and methods.
	BuildSParameterString	Creates the selector string to use with S-Parameter configuration or fetch methods and methods.
	BuildWaveString	Creates the selector string to use with Wave configuration or fetch methods and methods.
	CalibrationAbort	Stops calibration associated with signal instance that you specify in the selectorString parameter, which was previously initiated by the CalibrationInitiate(String). Calling this method is optional, unless you want to stop a calibration before it is complete. This method executes even if there is an incoming error.
	CalibrationAcquire	Measures one or more calibration standards for the specified calibration step. The recommended sequence of operations to call this method is illustrated below: [START] -> ... -> [Configure Calibration Settings] -> [Call RFmxVNA Calibration Initiate method] -> [Acquire Calibration Step(i)] -> [Acquire Calibration Step(j)] -> ...->[END]. Here, "Acquire Calibration Step(i)" denotes a call to RFmxVNA Calibration Acquire method for the ith calibration step. When CorrectionCalibrationCalkitType is Electronic, a single call to this method acquires calibration data for all the calibration standards in the vCal module. When CorrectionCalibrationCalkitType is Mechanical, calibration data for only the active cal step is acquired. Specify the active cal step in the Selector String. Use BuildCalstepString(String, Int32) method to build cal step string.
	CalibrationInitiate	Commits the calibration settings. RFmx creates calibration-steps required to perform calibration. Call this method after configuring the calibration settings. After calling this method, if you change any calibration setting, you must call this method again to commit the change(s) to said calibration setting(s).
	CalibrationSave	Computes error-correction terms and saves the calset in memory. Call this method after calibration data for all calibration steps have been acquired using CalibrationAcquire(String, Double) method. To perform another calibration after you call this method, you must call CalibrationInitiate(String) method again. Computed error-correction terms will be saved to calset in memory for the signal specified in Selector String input. If you specify Calset Name, error-correction terms will also be saved to the specified calset and made available globally for use by all signals.

If you do not specify both signal name in Selector String and Calset Name, the error term will be loaded from specified file to in memory calset of default signal instance. If you do not specify Calset Name but specify signal name in Selector String, the error term will be loaded from specified file to in memory calset of the specified signal instance. If you specify only Calset Name, the error term will be loaded from specified file to the global calset with the specified calset name.

If you do not specify Calset Name but specify signal name in Selector String, the error term will be saved to specified file from in memory calset of the specified signal instance. If you specify only Calset Name, the error term will be saved to specified file from the global calset with the specified calset name.
