Use optical and radio frequency measuring instruments

Assessment tool

Version 1.0
Issue Date: March 2024


This unit describes the skills and knowledge required to set up and use hand-held optical and radio frequency (RF) communications instruments to perform installations, upgrades and fault-finding on optical and RF equipment.

It applies to individuals who are able to combine technical skills with organisational and administrative skills. They often work as members of a team and communicate well with others.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

perform radio frequency (RF) measurements using hand-held instrument

operate the following equipment:

hand-held optical power meter

hand-held optical source

radio frequency (RF) signal level meter (SLM)

perform the following optical measurements:

detect the presence of an active optical network terminal (ONT)

determine absolute optical power (in dBm)

determine insertion loss (in dB)

determine relative optical power level (in dB)

perform the following RF measurements:

determine absolute RF power (in dBm)

determine relative RF power level (in dB)

determine relative RF voltage (in dBmV).

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

identify and describe the various instruments used in measuring RF and optical frequencies

list the types of measurements and their respective interpretation for optical and RF frequencies

explain the consequences of mating contaminated optical connectors

correctly record and discuss data using the units decibels, dBm and dBmV

discuss the variations between optical and RF connector types

identify and describe the WHS hazards and risks, and describe controls when working with RF frequency measuring equipment

outline RF spectrum and optical spectrum limits and allocations

discuss safe handling procedures with optical fibres.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the telecommunications – broadband and wireless networks field of work and include access to:

a site where measuring instruments can be used

plant, tools and equipment 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.
