Page 5 shows settings related to the HPA 1:1 Redundant System operation.
•
Mode
— Indicates HPA operational mode. See
Section 2.3.3.4
.
•
Stby
. — Shows the HPA standby state selection. “Hot” - Hot standby op-
eration (HPA retains unmuted state during standby); “Cold” - Cold
standby (HPA always mutes itself in standby mode and unmutes when
switched online).
•
Ctrl
. — Shows HPA control style. “Local” - Both local and remote control
are supported; “Remote” - When only remote control provided (keypad
locked);
•
Switch
— Indicates switching style. “Auto” - Automatic fault tracking/
switching; “Manual” - If redundancy switching is provided by the operator.
•
Unit
— Redundancy topological factor. “HPA1” - HPA connected to RF
switch port 1 or 4 (Online Position 1 of the RF switch); “HPA2” - HPA
connected to RF switch port 2 or 3 (Online Position 2 of the RF switch).
•
FSpeed
— Displays the current fan speed setting of “Hi”, “Low” or “Auto”.
2.3.1.6 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 sup-
ply. 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.
2.3.1.7 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 dis-
played.
