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.

Why is SINAD important?

SINAD - Signal to Noise and Distortion is a measure of receiver sensitivity performance used for many radio receivers and radio communications systems. SINAD, Signal to Noise and Distortion is a widely used measure of radio receiver sensitivity performance.

What is 12 dB SINAD?

A SINAD value of 12 dB, corresponds to a 4:1 SNR or a signal containing 25 percent distortion. THE SINAD RECEIVER MEASUREMENT. To make the SINAD measurement a known signal, a 1 kHz audio tone is typically used to modulate the carrier frequency for which the receiver is tuned for proper demodulation.

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.
