MONITOR MENU
CORRECTED BER
The CBER display shows an estimated corrected bit error rate of the modem.
Depending on the symbol rate the modem is running, the high-end
performance scale of this display will vary (10 E
-9 , 10 -10 or 10 -11 ). At some
symbol rates, a better than scale reading will appear as 0.0 x 10 -00 . At other
symbol rates, it will appear as E**. In either case, they both mean performance
is better than the scale upper limit.
