High Voltage Level
Command Byte:
‘N’
Function:
Allows the user to drop the high voltage by 1kV to improve tube
performance on certain units.
Parameters:
‘1’ - Reduces the high voltage level (sets Ku band mode).
‘0’ - Restores the high voltage level to its default state.
Compatibility:
Triband HPAs only.
High Voltage Off
Command Byte:
‘A’
Function:
Turns off high voltage. If the unit is in Filament time Delay, this
command ensures that high voltage will not turn on when Filament Time
Delay ends.
High Voltage On
Command Byte:
‘@’
Function:
Turns high voltage on. If the unit is in Filament Time Delay, high
voltage will automatically turn on when Filament Time Delay ends.
Low RF Trip
Command Byte:
‘L’
Function:
Sets a Low RF trip point. If output power drops below the set
point, an alarm or fault is generated provided the HPA has processed an
“Enable RF Limits” command (‘R’).
Parameter:
“AXXXX” to set an Alarm trip point,
“FXXXX” to set a Fault trip point, “D” to disable. XXXX is the desired trip point
in Watts.
Optional Parameter:
“M” - desired power in dBm.
Example: LAMxx.
