This specification describes the control functions of the HPA. Many control functions can be applied
locally from the front panel of the HPA as well as remotely via the serial interface. Some of the control
functions can only be applied via the local controls on the HPA. The following paragraphs specify these
control functions and the LOCAL/REMOTE capability. Details of the communication protocol for serial
control and the menu system for the local control are detailed in the operation and installation manual for
this HPA product. Please refer to that document for detailed information.

Note: Heater Standby reduces the TWT's heater voltage for situations where the high voltage is
off. Using this mode significantly increases the life of the TWT where high voltage is off
for extended periods of time.
