How is SINAD measured?

It is the ratio of Signal+Noise+Distortion divided by Noise+Distortion, expressed in dB. SINAD is measured using the test set's Audio Analyzer. SINAD can be measured in the range of 100 Hz to 10 kHz.

How do I find SINAD?

A procedure for testing the SINAD of a radio might follow a procedure like that given below: With no signal present on the input, the noise and distortion of the receiver are measured at a convenient level. A signal is applied to the input such that the output increases by 12 dB.

What is a good SINAD value?

This 0.25 μV value is typical for VHF commercial radio, while 0.35 μV is probably more typical for UHF. In the real world, lower SINAD values (more noise) can still result in intelligible speech, but it is tiresome work to listen to a voice in that much noise.

SINAD measurements

SINAD is an abbreviation for SIgnal-to-Noise And Distortion. It is a measure of audio quality used in low signal-to-noise ratio situations such as radio communications systems. SINAD is usually performed with a stimulus signal of 400 Hz or 1 kHz.
