3. Press the [

Enable

] key and the [

HV ON

] key at the same time. The

high voltage ON indicator should light (green). This indicates that
high voltage is ON and applied to the TWT. The Standby and Htr
Standby Indicators should turn OFF.

4. Select Local or Remote operation.

The TWTA is on-line.

Normal Turn-Off

When the amplifier is going to be off for an extended period turn
the High Voltage OFF. Then set the AC Power Switch to OFF
(

). This will extend the life of the TWT. For short periods of off

time (one hour or less), it is best to switch to the HV OFF (in
Heater Standby mode.)
