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.

public int SelfCalibrateRange(string selectorString, RFmxInstrMXSelfCalibrateSteps stepsToOmit, double minimumFrequency, double maximumFrequency, double minimumReferenceLevel, double maximumReferenceLevel)

Parameters

NameTypeDescription
selectorStringstring

Specify an empty string as the value of this parameter.

stepsToOmitRFmxInstrMXSelfCalibrateSteps

Specifies which calibration steps to skip during the self-calibration process.

PreselectorAlignment

Not used by this method.

GainReference

Not used by this method.

IFFlatness

Not used by this method.

DigitizerSelfcal

Not used by this method.

LOSelfCal

Omits 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.

AmplitudeAccuracy

Omits the Amplitude Accuracy step. If you omit this step, the absolute accuracy of the device is not adjusted.

ResidualLOPower

Omits the Residual LO Power step. If you omit this step, the Residual LO Power performance is not adjusted.

ImageSuppression

Omits the Image Suppression step. If you omit this step, the Residual Sideband Image performance is not adjusted.

SynthesizerAlignment

Omits the VCO Alignment step. If you omit this step, the LO PLL will not get adjusted.

DCOffset

Omits the DC Offset step.

minimumFrequencydouble

specifies the minimum frequency for the custom self calibration range. This value is expressed in Hz.
Note

For the PXIe-5830/5831/5832, only the applicable ports within the specified frequency range are calibrated.

maximumFrequencydouble

specifies the maximum frequency for the custom self calibration range. This value is expressed in Hz.

minimumReferenceLeveldouble

specifies the minimum reference level for the custom self calibration range. This value is expressed in dBm.

maximumReferenceLeveldouble

specifies the maximum reference level for the custom self calibration range. This value is expressed dBm.

Returns

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