Application
This unit describes the skills and knowledge required to design, install, test and commission a complex digital reception system.
It applies to individuals who work on complex radio frequency (RF) and digital distribution systems, such as master antenna television (MATV) and satellite master antenna television (SMATV), in commercial or multi-dwelling unit (MDU) environments.
Work functions in occupational areas where this unit may be used are subject to regulatory requirements. Refer to the ICT Implementation Guide Companion Volume or the relevant regulator for details of licensing, legislative or certification requirements.

Evidence of Performance
Evidence of ability to:
obtain relevant approvals for access to site and equipment
plan, assemble and install a complex digital reception system
conduct functionality tests and interpret results
examine performance of adjustments (tuning, balancing and replacing components)
perform handover with customer
apply related work health and safety (WHS) requirements and work practices.
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 procedures and equipment required for measurement of:
forward and reflected radio frequency (RF) power
feedline insertion loss
distance to fault
modulation error rate (MER) and bit error rate (BER) for purpose of signal integrity
identify features of instruments, test equipment and performance requirements
review legislation, codes of practice and other formal agreements directly impacting operation and testing of radio communications antennas and equipment
summarise principles of master antenna television (MATV) and satellite master antenna television (SMATV)
describe RF spectrum and its relationship to digital reception systems
discuss RF awareness, electromagnetic radiation (EMR) standards and specific WHS requirements impacting use and testing of radio communications instruments and equipment
outline typical issues and challenges that occur in telecommunications antenna installations
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 – Digital Reception Technology industry and include access to:
site for complex digital reception system installation
complex digital reception systems currently used in industry
test equipment required for digital reception system installation and testing.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
