CDM-625 Advanced Satellite Modem
Front Panel Operation
5.6.4
Monitor: Rx Parameters
Rx-Parameters: EbNo=11.4dB
BER=0.0E-9
If the demodulator is locked, this screen shows the following:
Eb/No
ΔF
BER
Buffer
Rx-Level
5.6.5
Monitor: AUPC-Parameters
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
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:
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
This is an identical screen and the same performance information as shown via Section 5.4.13.3
CONFIG: IP
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.
