MANDATORY CONFIGURATION REQUIREMENT
1. Purpose of the Bid
1.1. The Independent Communications Authority of South Africa (hereinafter referred to as “the Authority”)
intends to procure 4 (Four) Portable Multi- Function Analysers which will enable the Authority’s
Regional offices to perform enforcement and spectrum management functions.
2. Description of the requirement
2.1. The Authority currently has to perform investigation functions at remotely located sites and
inaccessible areas. The Authority requires specialised portable devices capable of analysing radio
frequency emissions up to 26.5 GHz.
2.1. This equipment is to check compliance to radio frequency spectrum licenses and resolve harmful
interference.
2.2. Multi-function device refers to a single, portable Radio Frequency (RF) analyser capable of analysing
RF emissions as a Spectrum Analyser including Phase and Magnitude as a Vector analyser. It should
also be a portable 2 port vector analyser capable of measuring all 4 S-parameters, analyse
antennae and faults on cables, be able to measure power ( Internal or external probe will be
considered), have a built-in GPS for frequency reference and geo-tagging ,demodulate AM and FM
, have built in RF Pre- amplifier and have a Tracking Generator.
2. Technical specifications
These technical specifications define the minimum acceptable performance characteristics in order to
fulfil ICASA’s bid requirements as set out in this document:
3. Objectives of the Bid
4.1.
The scope of this specification is limited to the supply, and delivery of four (04) Portable Multifunction Analysers. This should include all accessories, measurement personalities, associated
options and or firmware to provide a complete solution with or without the use of external
equipment. Section 5 below details the hardware requirements of the equipment.

4.2.
The Authority needs to check compliance to radio frequency spectrum licenses and resolve
harmful interference in inaccessible areas as well as measuring phase and magnitude of
transmission paths and RF sub-assemblies.
4. Configuration requirements
This section defines the configuration and functionality requirements which are imperative in order to fulfil
the Multi-function Analyser requirements as set out in this document. Bidders are thus required to
demonstrate how the under-mentioned will be achieved. Please provide a comprehensive analysis to
these requirements, by indicating whether you comply or not. Failure to comply with any of the
requirements will lead to disqualification.
