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

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.
