Constant Power (Watts)
Command Byte
: 'G'
Function
: The HPA seeks the specified power level until Constant Power is terminated by
Goto Power
(Command
Byte ‘D’ or ‘E’) or
Terminate Constant Power
(Command Byte ‘H’). Also called "Auto Gain Stabilization," the
Constant Power (Watts) command allows the user to operate an amplifier over extended periods of time while
maintaining a set power level. Constant Power Mode is intended to compensate for gain drift (due to time or
temperature).
Parameter
: The desired power level in "XXXX" Watts.
Compatibility
: Attenuator required.
Optional Parameter
: “M” – desired power in dBm.
Example: GMxx.x
Terminate Constant Power
Command Byte
: 'H'
Function
: If active, Constant Power Mode is terminated.
Compatibility
: Attenuator required.
RF Inhibit
Command Byte
: 'I'
Function
: Inhibits RF drive to the TWT.
Compatibility
: Attenuator required.
Clear RF Inhibit
Command Byte
: 'J'
Function
: RF drive to the TWT is enabled.
Compatibility
: Attenuator required.
