Radio Operator- Electronics Maintenance Trainer
AM-FM
PC-USB Digital Oscilloscope/Spectrum Analyzer/Voltmeter/Signal Generator
Description
The Radio Operator-Electronics Maintenance
Trainer is designed to allow trainees to use
electronic equipment, such as multimeters,
oscilloscopes, spectrum analyzer, to test and
troubleshoot analog and digital circuits of a
modular two-band radio, from faulty
cards/modules down to component level.
Circuit Cards
The interconnect board in the chassis can accept
up to a maximum of six functional or faulted
circuit cards from the following selection:
• AM & FM Power Supply
• AM Generator
• AM & FM Audio
• AM Power Amplifier
• FM Generator
• FM RF Stage
• FM Power Amplifier
• FM IF Stage
Fault Insertion
Instructors can insert different versions of
pre-faulted cards or defective accessories that
appear in no way different from functional ones
to build-up a defect that will cause one or several
modules to malfunction. As in real radios, one
faulty card can affect other completely-functional
cards, thus allowing very realistic troubleshooting.
The faults include open resistors, open and
shorted capacitors, open traces, open and
shorted transistor junctions, open inductors,
open and shorted diodes and LEDs, faulted
relays, faulted logic gates and faulted operational
amplifiers.
Complete schematic circuit diagrams are
supplied with the trainer
