CDM-625 Advanced Satellite Modem Revision 1
Front Panel Operation MN-0000036 (Ref MN/CDM625.IOM)
5.6.4 Monitor: Rx Parameters
Rx-Parameters: EbNo=11.4dB
Δ
F=+011.7kHz
BER=0.0E-9 Buffer=51% RxLevel=-43.5dBm
If the demodulator is locked, this screen shows the following:
Eb/No
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).
Δ
F
The frequency offset of the received carrier, in kHz, with a displayed resolution
of 100 Hz.
BER
This is an estimate of the corrected BER.
Buffer
(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.
Rx-Level
A dBm reading indicating the signal level of the desired receive carrier.
Resolution: 0.5dB
5.6.5 Monitor: AUPC-Parameters
AUPC-Params: Remote EbNo= 6.8 dB
Transmit Power Increase= 1.2 dB
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
lower 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.
5.6.6 Monitor: CnC-Parameters
CnC-Params: Freq-offset=-123.4kHz
Ratio:+12dB Delay=123.4ms
If enabled and locked, the display will show the CnC performance data. This menu updates once
every second.
5.6.7 Monitor: IP-statistics
IP stats: Port x In Out (
34v
)
Unicasts: 00000003 00000023 Clr:N
This is an identical screen and the same performance information as shown via
