Rfsa
Self-calibrates the NI-RFSA device and associated modules that support self-calibration.
Namespace: NationalInstruments.ModularInstruments.NIRfsa
Assembly: NationalInstruments.ModularInstruments.NIRfsa.Fx45 (in NationalInstruments.ModularInstruments.NIRfsa.Fx45.dll) Version: 2025
Syntax
public void SelfCalibrate( RfsaSelfCalibrationSteps stepsToOmit )
Public Sub SelfCalibrate ( stepsToOmit As RfsaSelfCalibrationSteps )
Parameters
- stepsToOmit RfsaSelfCalibrationSteps
- Specifies which calibration steps you want to skip as part of the self-calibration process. A value of "None" specifies that no calibration steps are omitted.
Exceptions
| Exception | Condition |
|---|---|
| ObjectDisposedException | The SelfCalibrate(RfsaSelfCalibrationSteps) method was accessed after the associated NIRfsa object was disposed. |
Remarks
If self-calibration is performed successfully, the new calibration constants are stored immediately in the self-calibration area of the module EEPROM. Refer to the specifications document for your device for more information about how often to self-calibrate.
For best results, NI recommends that you perform a complete self-calibration without omitting any steps. However, if the IsSelfCalibrationValid indicates that the calibration data for a specific step is still valid, you can omit that step for faster execution.
The IF Flatness step can take approximately 15 minutes to complete on the PXIe-5665 (3.6 GHz) and approximately 25 minutes to complete on the PXIe-5665 (14 GHz).
The IF Flatness step can take approximately 1 minute to complete on the PXIe-5667 (3.6 GHz) and approximately 1.5 minutes to complete on the PXIe-5667 (7 GHz).
The IF Flatness step can take approximately 15 minutes to complete on the PXIe-5668.
If there is an existing NI-RFSG session open for the same PXIe-5820/5830/5831/5832/5840 while this method runs, it may remain open but cannot be used for operations that access the hardware.
