Monitor: Rx Parameters Rx-Parameters: Ebno=11.4Db ∆F=+011.7Khz - Comtech EF Data CDM-425 Installation And Operation Manual

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.

•
(B) Number of Rx ModCod changes, in hex format, during the measurement interval.
•
(21.6,21.6) Finally, the 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:
