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.

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)
.
