Making the Monitor Band/Channel
Measurement

Purpose

This measurement verifies the GSM band and channels are free of
interference by measuring the spurious signals in the bands and
channels specified by the selected standard and tuning plan.

Measurement Method

This procedure scans the specified band or channels and by placing
markers on the trace it is possible to check the band/channels for
interference. A Max Hold function enables monitoring over time. This is
useful when the interference is intermittent.
