What is the space between adjacent frequency components when using these VIs? How can I change the spacing?
Most of these measurement VI’s provide an output labeled “df”. This is the frequency difference between adjacent components, measured in Hz if dt (the difference between time domain samples) is provided to the VI in seconds. df is explicitly calculated as fs / N, where fs is the sampling frequency and N is the length of the time-domain sequence. In order to change df, you must change either fs or N.
