2.1 Introduction
This section covers the tests which should be undertaken prior to handover of the radio to the end
user. All of the following tests can be carried out without having to gain access to the interior of the
radio.
Recommended Test Equipment
The alignment and performance test procedures assume the use of the following equipment. The
functions of most of the equipment may be found in a “Communications Test Set”. This type of
equipment is available from a number of test equipment manufacturers.
Throughout this book reference will be made to the use of the Communications Test Set. Where
applicable, the equivalent discrete item of test equipment may be used. For example, if measuring
power, a stand-alone power meter and a dummy load could be used instead of the Test Set
