This page shows individual RF module states in multi-module HPAs.
•
Mod# & PreAmp
— Mod1 to Mod4 represent the overall state of the rel-
evant RF Power modules. If the amplifier is equipped with a separate
-amplifier module, the “PreAmp” value will represent the overall state of
the pre-amplifier. Under normal operation, the value will read “Normal”.
If a unique module does not exist in the HPA configuration, the value
shows “N/A” (not available). Each value represents the summary fault
state of an individual RF module, which includes the Voltage, Current and
Temperature state as well as the quality of data connection with module.
For a module or pre-amp exhibiting a fault, the value will read “FAULT!”.
If the HPA controller card cannot reliably communicate with an SSPA
module, that module will be declared faulted. This type of fault will not af-
fect the overall summary fault state, because the controller card has the
ability to track RF module faults independently. When an existing module
or pre-amp is present in the current HPA configuration, but fails to re-
spond to control board status queries, “ComErr” (Communication Error)
will be displayed.
•
PSModFlts
— For amplifiers utilizing an external N+1 power supply, this
value indicates the number of detected N+1 PS module faults. For units
with an internal power supply, this value reads “000” and should be ig-
nored. Check PS1 and PS2 Voltage readings to assess the state of an
internal power supply.

This page shows various miscellaneous operation parameters.
•
Chssy Temp
— Chassis temperature reading measured by the control
board. Since the control board is typically located at rear of the chassis,
this reading correlates with the exhaust air temperature;
•
RecordHigh
— The highest temperature detected over unit lifetime. This
value is updated each time a temperature higher than the current record
is detected. Value could be used for SSPAs problem troubleshooting.
Record data is factory reset only.
•
BUC PS1(V)
— This value represents the power supply voltage used for
biasing an optional BUC unit. Voltage could be used for detecting prob-
lems related to BUC operation. The SSPA does not have a specific alarm
threshold for this voltage. Normal reading for this parameter should be in
range of 15V– 16V.
•
BUC PS2(V)
— This value represents secondary BUC power supply volt-
ages. For a unit equipped with a single power supply this value shows “N/
A” (not available).
