test a radio communications device.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
explain electrical symbols and circuit diagrams
summarise the general principles of radio communications and radio propagation
identify and outline the characteristics of:
radio communications components
device pinouts
part numbers
polarities
ratings
summarise the operation and characteristics of:
amplifiers
demodulators
mixers
modulators
oscillators
explain the principles of modulation.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications – radio frequency networks field of work and include access to:
sites where radio communications devices may be constructed and tested
test instruments currently used in industry
relevant regulatory and equipment documentation that impacts on work activities.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
