Functional Description

The MBT-4000 is designed to perform the following functions:



C-, X-, or Ku-Band RF to L-Band down conversion



L-Band to C-, X-, or Ku-Band RF up conversion



RF Band switching in minimal time without requiring tools



Easy expansion for providing a redundant system or other frequency bands



Automatic band identification for the Block Up converter (BUC), Block Down Converter
(BDC), and antenna feed (if the feeds provide an identifying connector)



System status verification via LEDs located behind a removable cover
