Raw BER: Displays the estimated channel error rate (before decoding)
measured by the modem. This window is active continuously
and is above the Gel Tab area.
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. This window continuously is
active and is above the Gel Tab area.
