public int SetFftPadding(string selectorString, double value)
Remarks
This method sets the value of IMFftPadding attribute.The default value is -1.
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name that is passed when creating the signal configuration is used. |
| value | 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 method 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.
