SFC4200/SFC1275G Synthesized Frequency Downconverter Maintenance
TM054 - Rev. 4.0 6-1
Section 6 - Maintenance
6.0 Periodic Maintenance
Radyne ComStream Corporation SFC Downconverters are designed to provide many thousands
of hours of continuous operation. Normal aging and drifting of electronic components can cause
the accuracy of the converter to change over time. As with any converter, these changes will
affect the frequency accuracy and frequency conversion amplitude accuracy over time.
6.1 Failure Analysis
Faults in the converter are limited in scope to either a LO Fault or a Signal Fault. Other faults
may or may not provide an indication such as a failure of the microcontroller.
