Introduction SFC4200/SFC1275G Synthesized Frequency Downconverter
1-2 TM054 - Rev. 4.0
The SFC Downconverters have been designed to provide performance that meets or exceeds all
industry standards in effect today for satellite communications earth station frequency converter
equipment found worldwide. In addition to providing robust performance, the SFC
Downconverters are loaded with features that will provide ease of integration and operation.
1.1 Protection Switch Versatility
Radyne ComStream Corporation SFC family of Converter Products feature ‘plug-and-play’ ease
of installation with the RCU101 1:1 or the RCU108 1:8 Redundancy Control Units. All converters
can be plugged into the backup slot and assume the role of protection switch controller. The
backup converter learns and stores the frequency, gain and channel settings of the primary
converters. If the stored setting of the primary converter is changed, the backup converter will
notify the user via the front panel and the RS-232/RS-485 interface.
All circuits are protected upon installation of the switch and completion of the learning process.
This eliminates the need for complicated software configurations that might otherwise leave a
circuit vulnerable. Likewise, replacing a failed converter is as simple as plugging in a
replacement.
