Threshold level for signal to noise ratio (dB)
Threshold level for minimum signal strength.
This is a measure of the stream signal power. It is expressed
according to the level mode selection made in the Setup -
ETR view:
dBm: in decibels relative to a reference value of 1mW
dBuV: in decibels relative to a reference value of 1µ V
dBmV: in decibels relative to a reference value of 1mV
