Stored Event: Clear-All; Monitor: Lpt (Low Power Threshold) - Comtech EF Data MBT-5000A Installation And Operation Manual

Stored Event: Clear-All

Clear all Stored Events?
(◄ ► E)
No Yes
As prompted, use the ◄ ► arrow keys to choose No or Yes, and then press ENTER. If you
select Yes, the event log is cleared and the user is returned to the previous menu. However, if
faults remain present at this time, they MBT-5000A re-stamps them and generates new log
entries.
5.2.3.4

Monitor: LPT (Low Power Threshold)

Low Power Threshold:
ConvA ConvB
When the MBT-5000A is optionally configured, use this menu to set the threshold, in dBm, for the
low forward power alarm/fault. If the forward power drops below the specified value while the unit
is online, is unmuted, and PLL is locked, the MBT-5000A will indicate the alarm/fault.
Use the ◄ ► arrow keys to select ConvA or ConvB, and then press ENTER. Where 'X' is the
selected converter – Converter (Side) A or Converter (Side) B:
ConvX LPT = +00.0 dBm
Use the ◄ ► arrow keys to first select the digit to edit, and then use the ▼▲ arrow keys to edit
the value of that digit.
Note the following:
•
The valid range for this parameter is from the unit's specific P1dB power level to P1dB
minus 19 dB.
For example: For a unit with +12 dBm at P1dB, the range would be +12.0 to -7 dBm.
•
The default value is -20.0 dBm. Setting the parameter to this default value effectively
disables the threshold.
•
If Power Monitoring is not supported, and you select ConvA or ConvB, the following
message displays:
This Converter Does NOT
Support Power Monitor.
Press ENTER when done or CLEAR to return to the previous menu.
