Comtech EF Data CDM-625 - Manual (Page 314)

CDM-625 Advanced Satellite Modem Revision 15
Automatic Uplink Power Control (AUPC) MN-CDM625
8–4
8.4 Monitoring
CAUTION – Comtech EF Data strongly cautions against the use of large values of
permitted power level increase under AUPC control. You should consider using the
absolute minimum range necessary to improve rain-fade margin.
The remote demodulator’s value of Eb/No can be monitored at all times, either from the front
panel (SELECT: Monitor  AUPC) or via the remote control interface. The resolution of the
reading is 0.2 dB. For all values greater than or equal to 16 dB, a value of 16.0 dB will be
displayed. As long as framing is enabled, the value will still be available, even though AUPC may
be disabled.
The current value of Tx power increase is also displayed. If EDMAC framing is enabled but AUPC
is disabled, this will indicate 0.0 dB. This value is also available via the remote control interface.
