VASI Posted June 7, 2013 Report Share Posted June 7, 2013 Reading the manual from Lectrosonics SRb about sensitivity they have: 20 dB SINAD: 1.0 uV (-107 dBm), A weighted 60 dB Quieting: 2.2 uV (-100 dBm), A weighted About SINAD But I can't find what is "Quieting" and I'm curious what it is.

LarryF Posted June 7, 2013 Report Share Posted June 7, 2013 The receiver's hiss (white noise like) is measured first with no carrier (RF signal) and the squelch bypassed. The hiss will typically be at full output level. It is then is suppressed (quieted)when an RF signal with no modulation is fed into the receiver. The necessary RF level to suppress the hiss 60 dB is the quieting level. Best, Larry F Lectro Quote Link to comment Share on other sites More sharing options...
VASI Posted June 7, 2013 Author Report Share Posted June 7, 2013 So we have first the hiss before RF carrier and after in RF carrier and processing. Correct? Quote Link to comment Share on other sites More sharing options...
