MN-SLM-5650A
7.2.4.3 (Monitor:) Rx-Params
Fc=+05917 RSL<-60.0 dBm BERT=N/A
Buf=000% Eb/No=Loss BER <1.0E-12 (
E)
This
read-only
screen monitors the following Rx operating parameters:
•
Fc
displays the received carrier frequency offset in Hz. The range is the same as the
acquisition range of the modem (60 kHz).
•
RSL
displays the signal level of the received carrier in dBm. The range supported is
(+15) to (-60) dBm.
•
BERT
displays the measured BER. This requires that the modem be set to
Test
mode for
Rx. If a Fireberd is supplying a data pattern, only the
Test
mode for the Rx needs to be
turned on. The Fireberd data pattern and the modems’ data patterns must match to work
properly.
•
Buf
displays the buffer fill status as a percentage.
•
Eb/No
displays the estimated Eb/No of the received carrier. The range is threshold to 20
dB Eb/No.
•
BER
displays the estimated BER based on the demodulator’s measurement of the carrier
to noise.
The difference between BERT and BER is that BERT is measured when
the Test mode is turned ON, whereas BER is estimated in the
demodulator.

7.2.4.4 (Monitor:) CnC (DoubleTalk® Carrier-in-Carrier®)
CnC: Delay=000,005uS FreqOff=008.7kHz
Eb/No=Loss Ratio<-10dB (E)
This
read-only
screen updates once every second. If enabled and locked, this screen monitors
the CnC performance data:
•
Delay
displays the current search delay value.
•
FreqOff
displays the current frequency offset between the outbound interferer and the
desired inbound.
•
Eb/No
displays the estimated Eb/No of the received carrier. The range is threshold to 20
dB Eb/No.
•
Ratio
displays the ratio of outbound interferer power to desired inbound power. The
range is ±10 dB.
