Ratio between carrier level and the channel's noise
level.
Ratio between the channel power and the noise
level. The frequency where noise is measured is
user definable in absolute or relative value. In the
relative mode, the unit takes as default frequency
offset the value BW/2 + 0.5 MHz.
40-50 dB for input level between 60 and 70 dBµV.
> 50 dB for input level > 70 dBµV.
> 30 dB for input level > 60 dBµV.
