recorded for each instance.  A yellow LED will remain illuminated until
the event counter is reset to zero.  (This feature is not available in
firmware version 1.1.0 and  prior releases)

Over Temperature Limit:   

Amplifier junction temperature is monitored

continuously.  If the temperature rises above a factory determined
limit, an Overheat Event will be recorded.  If the event is transitory,
each excursion above the limit will increment the Overheat counter.  A
yellow LED will remain illuminated until the counter is reset to zero.

Event counters serve as diagnostic tools for maintenance and system health
assessments.  Only isolation control will alter the intended performance of the
system.  Fan and Overheat events have no effect on the BDA.

Pressing 

MENU

 within at this display will advance the user to the Peak Power

Display.

Peak Power Readout Display

This display shows the highest readings that have registered on the BDA
since power-up or reset.

A typical display might look like this:

Note that since AGC cannot act instantaneously, the peak power seen on the
output might be higher than the power the unit is capable of sustaining.  This
is not an error, but an indication that the power did exist – briefly – at the
output port.  This is meant to aid in diagnostics if necessary.

Pressing the 

MENU

 button will advance the user to the Downlink Gain display.

Gain Display

This display indicates the gain applied to the uplink or downlink pass band.
These values might differ if an offset has been applied.

A typical gain display might look like this:

Pressing the 

MENU

 button will advance the user to the BDA Name Display.
