SINAD Measurement
SINAD is the measure of the ratio of the signal+noise+distortion to the
noise+distortion produced at the output of a receiver that is the result
of a modulated signal input. This ratio is expressed in dB.
See "SINAD, Distortion, SNR, AF Frequency, DC Level," on page 38 for
more information.

SNR Measurement
The is signal to noise ratio of the audio input signal.
See "SINAD, Distortion, SNR, AF Frequency, DC Level," on page 38 for
more information.
Operating Considerations
Selecting SNR turns off any other audio measurements.
The RF generator and audio frequency generator 1 (AFGen1) must
be set up to provide the radio’s carrier. (AFGen1 is automatically
turned on and off repeatedly during this measurement.)
The AFGen2 To field on the RF GENERATOR screen must be set to
Off.
The audio output of the radio’s receiver must be connected to the
AUDIO IN port (set the AF Anl In field on the AF ANALYZER
screen to Audio In).
