OBW:FFT:Padding Property

OBW:FFT:Padding Property

Short Name: OBW FFT Padding

Property of RFmxSpecAn

Specifies the factor by which the time-domain waveform is zero-padded before fast Fourier transform (FFT). The FFT size is given by the following formula:

waveform size * padding

This property is used only when the acquisition span is less than the device instantaneous bandwidth of the device.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is -1.
