CDM-600L Satellite Modem
Front Panel Operation
6.3.4.4
MONITOR: RX PARAMETERS
RX=PARAMETERS: EbNo=11.4dB
BER=0.0E-9
If the demodulator is locked, this screen shows the following:
Eb/No
∆F
BER
BUFFER
RX-LEVEL
6.3.4.5
MONITOR: AUPC-PARAMS
AUPC-PARAMS:
The top line displays the value of Remote Eb/No of the demodulator at the distant end of
the satellite link. The Remote Eb/No will display UNLOCK if the remote DEMOD is
unlocked.
The bottom line shows how much the AUPC system has increased the output power. If
AUPC is not enabled, the value of TX POWER INCREASE will show as 0.0 dB.
BUFFER=51%
This shows the value of Eb/No calculated by the demodulator. The value
referred to here is the energy per information bit (Ebi), divided by the noise
spectral density (No).
The frequency offset of the received carrier, in kHz, with a displayed
resolution of 100 Hz.
This is an estimate of the corrected BER.
(Buffer fill state) This shows the fill state (in percent), of the receive Buffer.
After a reset, it will read 50. A value <50 indicates that the buffer is
emptying, and >50 indicates that it is filling.
A dBm reading indicating the signal level of the desired receive carrier.
REMOTE EbNo=6.8dB
TRANSMIT POWER INCREASE=1.2dB
∆F=+11.7kHz
RX-LEVEL=-43dBm
