Configures the window and FFT to obtain a spectrum for the IM measurement.
Syntax
Namespace: NationalInstruments.RFmx.SpecAnMX
public int ConfigureFft(string selectorString, RFmxSpecAnMXIMFftWindow fftWindow, double fftPadding)
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name that is passed when creating the signal configuration is used. |
| fftWindow | RFmxSpecAnMXIMFftWindow | Specifies the FFT window type to use to reduce spectral leakage. Refer to the Window and FFT section of the Spectral Measurements> topic for more information about FFT window types. |
| fftPadding | double | Specifies the factor by which the time-domain waveform is zero-padded before an FFT. The FFT size is given by the following formula: FFT size = waveform size * padding. This parameter is used only when the acquisition span is less than the device instantaneous bandwidth. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
