Power Amplifier menu (P.A.)
This multi-line scrollable menu reports to the user some internal measurement of
the device:
•
Voltage (VPA) - Not active
•
Current (IPA) - Not active
•
Efficiency - Not active
•
Temperature
•
Mains voltage (Mains - percentage variation with respect to the nominal voltage)
The complete aspect of the screen is the following figure (please note that only
two lines at a time are visible, use the UP and DOWN buttons to scroll):
5.3.4
Threshold setting menu
As described in the introduction, the amplifier offers a maximum of four user settable
alarms. For each of them, one of the working parameters is compared against a
threshold value that can be be modified by the user. The results of the comparisons
are available on the telemetry connector or as dry contacts on the optional external
telemetry board, and can be read on the display as "O" (open, i.e. the result is
false) or "C" (closed, i.e. the result is true).
Two of the settable thresholds are related to the RF emitted power (Power Good),
while the third is connected to the amount of reflected power (Reflected Warning).
