CDM-625A Advanced Satellite Modem
MN-CDM625A
Front Panel Operation
Revision 4
6–83
Example 1:
08.0,13.5,2.5,1.8,30.0,25.1
means:
(08.0) Minimum Eb/No observed in the measurement interval = 8.0 dB
(13.5) Average Eb/No observed in the measurement interval = 13.5 dB
(2.5) Maximum TPLI observed in the measurement interval = 2.5 dB
(1.8) Average TPLI observed in the measurement interval = 1.8 dB
(30.0) Minimum RSL is observed in the measurement interval = -30.0 dB
(25.1) Average RSL is observed in the measurement interval = -25.1 dB
Example 2:
Loss,04.5,0.0,0.0,29.0,29.0
means:
(Loss) There was a loss of demod lock during the measurement interval
(04.5) Average Eb/No observed in the measurement interval = 4.5 dB
(0.0) Maximum TPLI observed in the measurement interval = 0 dB
(0.0) Average TPLI observed in the measurement interval = 0 dB
(which indicates no AUPC
activity, or that AUPC is disabled.)
(29.0) Minimum RSL is observed in the measurement interval = -29.0 dB
(29.0) Average RSL is observed in the measurement interval = -29.0 dB
The presentation of statistics information varies slightly when in IP-ACM or V2-ACM mode.
In IP-
ACM Mode:
Stats 115: 22.0,22.0,B,0,0,B,21.6,21.6
17/11/14 12:15:26 Clear-All: No (N/Y)
The modem calculates and then displays, on the top line from left to right, statistics data as
follows:
•
(22.0,22.0)
First, the SNR is calculated: The
minimum
SNR value observed during the
measurement interval is provided first, and then the
average
SNR observed value follows.
The screen displays 16.0 only if the measured values are
≥
16.0 dB.
•
(B)
Next, the Rx ModCod that was current when the entry was logged.
•
(0)
Maximum Rx ModCod, in hex format, during the measurement interval.
•
(0)
Minimum Rx ModCod, in hex format, during the measurement interval.
•
(B)
Number of Rx ModCod changes, in hex format, during the measurement interval.
•
(21.6,21.6)
Finally, the
Receive Signal Level (RSL) is calculated (note that both values are
negative): The
minimum
value observed in the measurement interval is provided first, and
then the
average
RSL observed value follows.
In V2-ACM Mode,
the modem calculates and then displays, on the top line from left to right,
statistics data as follows:
