Fault – FPGA Checksum
Use the ▼▲ arrow keys to scroll backwards or forwards through the entries in the event log.
The event log can store up to 300 events. When a fault condition occurs, the MBT-5000 time-
stampa it and puts it into the log. Similarly, when the fault condition clears, MBT-5000 records
this change, as shown per the following example:

No Yes (◄ ► E)
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-5000 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-5000 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-5000 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
