Signal to Noise and Distortion (SINAD)

SINAD is a common sensitivity measurement normally associated with FM receivers. It is an acronym for Signal plus noise and distortion and is equal to (S+N)/N in our system. It is expressed in dB. If the signal is much stronger than the noise then SINAD value approaches the SNR value. Otherwise SINAD will be greater than the SNR.

This utility window can be resized as required by the user and its contents will update anytime a new spectrum is computed. The window will contain the channel index and name; the channel name can be modified in the Calibration Settings.

Right clicking on the utility window will allow you to copy the contents to the clipboard.

Notes:

Hanning or Blackman smoothing window is recommended because of its low noise quality.

An FFT size of 2048 or greater is recommended in order to to provide adequate spectral resolution.
