Feature Description
EFData Part No. RF/XTC-111D
Auto Mode For automatic operation when switched from offline to online system.
Power Supply TWTA is power from an AC input.
Control Interface The control interface from the TWTA to the HPC is parallel (discrete) signal
lines.
Local Control Provides local control at the HPC site, or control from a remote site through a
remote control interface.
This is a manual selection at the HPC site.
Panels The front panel provides control switches and indicators. A rear panel of
discrete interface connections for the TWTA, an interlock connector input, and
a remote interface control connector. Also, an input is provided for the
waveguide switch position indicators. A fault indicator and fault reset is
provided for each channel.
