RFmxInstrMX.SelfCalibrateRange Method

RFmxInstrMXSelfCalibrateRange Method

Self-calibrates all configurations within the specified frequency and reference level limits. If there is an open session for NI-RFSG for your device, it may remain open but cannot be used while this method runs. NI recommends that no external signals are present on the RF In port while the calibration is taking place. For more information about Self Calibrate Range, refer to the niRFSA Self Calibrate Range method topic for your device in the NI RF Vector Signal Analyzers Help. On a MIMO session, this method self-calibrates all NI-RFSA devices and associated modules that support self-calibration.
supporteddevices: PXIe-5644/5645/5646, PXIe-5820/5830/5831/5832/5840/5841/5842/5860
This method does not update self-calibration date and temperature. Self-calibration range data is not saved to your device if you restart the system.

Syntax

public int SelfCalibrateRange(
	string selectorString,
	RFmxInstrMXSelfCalibrateSteps stepsToOmit,
	double minimumFrequency,
	double maximumFrequency,
	double minimumReferenceLevel,
	double maximumReferenceLevel
)
Public Function SelfCalibrateRange ( 
	selectorString As String,
	stepsToOmit As RFmxInstrMXSelfCalibrateSteps,
	minimumFrequency As Double,
	maximumFrequency As Double,
	minimumReferenceLevel As Double,

) As Integer

Parameters

selectorString  String
Specify an empty string as the value of this parameter.
stepsToOmit  RFmxInstrMXSelfCalibrateSteps
Specifies which calibration steps to skip during the self-calibration process.
PreselectorAlignmentNot used by this method.
GainReferenceNot used by this method.
IFFlatnessNot used by this method.
DigitizerSelfcalNot used by this method.
LOSelfCalOmits the LO Self Cal step. If you omit this step and the NI-RFSA IsSelfCalibrationValid method indicates the calibration data for this step is invalid, the LO PLL may fail to lock.
AmplitudeAccuracyOmits the Amplitude Accuracy step. If you omit this step, the absolute accuracy of the device is not adjusted.
ResidualLOPowerOmits the Residual LO Power step. If you omit this step, the Residual LO Power performance is not adjusted.
ImageSuppressionOmits the Image Suppression step. If you omit this step, the Residual Sideband Image performance is not adjusted.
SynthesizerAlignmentOmits the VCO Alignment step. If you omit this step, the LO PLL will not get adjusted.
DCOffsetOmits the DC Offset step.
minimumFrequency  Double
specifies the minimum frequency for the custom self calibration range. This value is expressed in Hz.

Note  Note
For the PXIe-5830/5831/5832, only the applicable ports within the specified frequency range are calibrated.
maximumFrequency  Double
specifies the maximum frequency for the custom self calibration range. This value is expressed in Hz.
minimumReferenceLevel  Double
specifies the minimum reference level for the custom self calibration range. This value is expressed in dBm.
maximumReferenceLevel  Double
specifies the maximum reference level for the custom self calibration range. This value is expressed dBm.

Return Value

Int32
Returns the status code of this method. The status code either indicates success or describes a warning condition.
