6-5 Suitable applications of each monitoring mode

A summary of the three monitoring modes and suitable applications is given

here:

Spectrum analyser mode

This mode is the DEFAULT and most common monitoring mode among the

three. It is suited to the monitoring of permanent or intermittent signals or

noise. The CF (centre frequency) and SPAN (visible bandwidth) are the main

criteria to be specified.

Step resolution mode

This mode is suited best to monitor signals which are allocated with certain

intervals over the band spectrum. The STEP is the criteria to be specified in

place of the SPAN, so that one dot is equal to one step on the display.

Channel scope mode

This mode is best suited to monitor known channelised frequency spectrums

such as VHF airband and FM sections or broadcast and ham radio bands.

The start frequency, end frequency and step have to be specified. There is no

concept of CF applied to this mode. It is most convenient to follow and listen

to the various signals by using both marker and receive markers.
