Controls
This specification describes the control functions of the HPA. A limited number of 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 REMOTE capability. Details of the communication protocol for serial control and the menu
system for the local control are detail in the operation and installation manual for this 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.
