MNC-0500-010 27 Revision D
Solid State Power Amplifier Communication and Protocol
Constant Power (dBW)
Command Byte : 'F'
Function : The SSPA 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 (dBW)
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 "XX.X" dBW.
Compatibility : Attenuator required.
Constant Power (Watts)
Command Byte : 'G'
Function : The SSPA 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.
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 SSPA.
Compatibility : Attenuator required.
