P804 Confidence Threshold
P806 Echo Strength
Displays the strength of the selected echo, in dB above 1 µV rms.
Values (view only) Display: 0 to 9
P807 Noise
Displays the average and peak ambient noise (in dB above 1 µV RMS) being processed.
x = average (-9 to 99)
Values (view only)
y = peak (-9 to 99)
The noise level is a combination of transient noise and electrical noise (receiving
circuitry).
