8) This describes the essential skills and knowledge and their level, required for this unit. Evidence shall show that knowledge has been acquired of safe working practices and finding and repairing faults in the microwave amplifier sections in electronic apparatus. All knowledge and skills detailed in this unit should be contextualised to current industry practices and technologies. KS01-EH116A Electronic communications systems Evidence shall show an understanding of software programming fundamentals, applying safe working practices and relevant Standards, Codes and Regulations to an extent indicated by the following aspects: T1. Microwave amplifiers Applications and operational constraints Operating principles and parameters Amplifier components and circuit configuration Amplifier faults, symptoms and causes T2. Electronic communications, microwave antennae and waveguide fundamentals Antenna and wave guide principles and components Installation techniques for microwave communication systems Setting up techniques for microwave communication systems T3. Advanced electronic (communication systems) testing and measuring devices and techniques Test/measuring devices and their application - frequency counters, and synthesisers, spectrum analysers, noise and distortion meters and RF communications service monitor. Connection of test/measuring devices into a circuit encompassing: safety procedures loading and matching storage and delay circuit arrangement of test/measuring devices Taking and interpreting readings Notion of decibels including dBm, dBr, dBu, dBo T4. Electronic (communication systems) fault finding Factors to consider in clarifying the nature of a fault encompassing: Initial fault report Confirmation of symptoms of the fault Comparison of symptoms with normal operation Effect to cause reasoning — assumptions of possible causes Methods for testing assumptions encompassing: Visual inspection Sectional testing Split-half tests Component isolation Dealing with intermittent faults - causes of intermittent faults are vibration, shock, changes in temperature and electromagnetic interference.
