Front Panel Operation	MN/CDMQx.IOM

If the measured values are greater than, or equal to 16.0 dB, the display will show

16.0dB. If AUPC is not enabled, the values of maximum and average TPLI will both show ‘Off'.

Examples:

08.0, 13.5, 2.5, 1.8 means:

Minimum Eb/No observed in the measurement interval = 8.0 dB Average Eb/No observed in the measurement interval = 13.5 dB Maximum TPLI observed in the measurement interval = 2.5 dB Average TPLI observed in the measurement interval = 1.8 dB

Loss, 04.5, Off, Off means:

There was a loss of demod lock during the measurement interval

Average Eb/No observed in the measurement interval = 4.5 dB

Maximum TPLI observed in the measurement interval = AUPC disabled

Average TPLI observed in the measurement interval = AUPC disabled

If the user selects Config, the following sub-menu is displayed:

(MonitorStatsClear-All) – CLEAR ALL STATS

If the user selects Clear-All, the statistics log is cleared, and the user is taken directly back to the previous menu.

Stats Logging Interval:

Disabled(▲▼,ENT)

The user is prompted to enter the logging interval (the period of time over which the statistics will be measured), using the STarrow keys, then press ENT. The user can choose Disabled, 10, 20, 30, 40, 50, 60, 70, 80, or 90 minutes.

Stats Logging Interval: 30 minutes (▲ ▼ ENT)
