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.
Making the Measurement
1. Press the Measure key.
2. Press the
Monitor Band/Channel key.
Example screens from making a band measurement are shown in
Figure 4-1 on page 4-4 and a channel measurement in Figure 4-2 on
page 4-4.
Factory default parameter settings provide a GSM compliant
measurement. For special requirements, you may need to change
default settings:
• Mode setup and frequency/channel parameters.
Use the
Mode Setup and Frequency Channel keys to change these
parameters for all measurements made within the current mode. For
further information refer to Chapter 1 of this document.
• Measurement setup parameters.
These are measurement specific parameters changed using the
Measurement setup (
Meas Setup) menu. Parameters can be returned
to default settings at any time by pressing
Meas Setup, More (1 of 2)
and
Restore Meas Defaults. For further information on measurement
setup parameters, refer to the ESA-E Series Spectrum Analyzers
GSM Measurement Personality Use’s Guide.
NOTE Parameters that exist under the Meas Setup Advanced key seldom need
to be changed. Any changes from the default values may result in
invalid measurement data.
