THEORY OF OPERATION
This chapter provides the basic theory of operation for the Monitor and Control (M&C)
board, high stability oscillator, IFLOs synthesizers, and the up and down converters.
5.1 Monitor and Control
The RFT-500 uses a sophisticated microcontroller module to perform the M&C functions
of the terminal. This board (refer to Figure 5-1) is located inside of theRFT-500, on top
of the other assemblies.
The M&C monitors the RFT-500 and provides configuration updates to other modules
within the terminal when necessary.
Terminal configuration parameters are maintained in EEPROMs, which provides for total
recovery after a power-down situation.
Fault monitoring and status gathering are also provided.
All RFT-500 functions are accessible through the local front panel keypad/display or a
remote communications interface.
Note: For more information on the M&C board, refer to Chapter 1.
