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 57 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 57 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).
