3.1.6 Sys Info Page 6
This page shows the status of the HPA’s internal power supplies.
•
PS1(V) — Main power supply 1 output voltage with resolution of 0.1V. Normal
output voltage for GaAs amplifiers is in the range of 11 to 13 V; Normal output
voltage for GaN amplifiers is in the range of 25 to 28 V.
•
PS2(V) — Main power supply 2 output voltage.
•
Boost1(V) — Booster power supply 1 output voltage with resolution of 0.1V.
Normal range 24 to 30 V (typical 28V);
•
Boost2(V) — Booster power supply 2 output voltage.
•
DC (A) — Total DC current draw by RF modules from main power supply. Value
varies depending on the power level of the HPA. If the HPA is muted, current
normally drops to within the 0 to 5 A range.
3.1.7 Sys Info Page 7
This page shows RF module related faults and conditions.
•
Regulator — RF module regulator low voltage fault. Values: “FAULT!” or
“Normal”;
•
DC Current — Low DC current fault. Values: “FAULT!” or “Normal”;
•
Temperature — High temperature fault. Values: “FAULT!” or “Normal”.
•
Temp.(C) — Internal RF module plate temperature in Celsius. In multi-module
units, only the hottest module baseplate temperature is displayed.
3.1.8 Sys Info Page 8
This page shows individual RF module states in multi-module HPAs.
•
Mod# & PreAmp — Mod1 to Mod4 represent the overall state of the relevant
RF Power modules. If the amplifier is equipped with a separate pre-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 indi-
vidual 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 condition, 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 affect the overall
summary fault state, because the controller card has the ability to track RF mod-
ule faults independently. When an existing module or pre-amp is present in the
current HPA configuration, but fails to respond to control board status queries,
“ComErr” (Communication Error) will be displayed.
