Model 20T4G18
CAUTION:
Do not adjust 20-turn pot R11; its function is to set the foldback RF
output level, and it is calibrated at the factory.
3.8 REMOTE IEEE-488 OPERATION
The TWTA is provided with a communication interface that conforms electrically to the IEEE-488 standard.
It permits remote emulation of OPERATE, STANDBY, and RESET push-buttons as well as access to
parameter measurements, system faults, gain adjustment, and control unit status. The following tables
summarize the commands and the return codes.
