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:
