Understanding GSM/EDGE Transmitter
and Receiver Measurements for
Base Transceiver Stations and
their Components
Application Note 1312
agilent
Introduction
This application note presents the fundamental RF parametric measurements
necessary to characterize GSM/EDGE base transceiver stations and their
components. The principles cover all GSM bands (P-GSM900, DCS1800,
E-GSM900, R-GSM900, GSM450, GSM480, GSM850, MXM850, PCS1900 and
MXM1900). Specific examples reference E-GSM900.
These measurements are widely used today, but new test equipment is making
them easier to perform, faster and more precise. This note aims to enhance
the reader’s understanding of GSM/EDGE measurements so they can be used
and optimized appropriately. It is also intended as a useful reference for engineers
in manufacturing, research and development and field service.
As far as possible, graphics are used to represent the theory behind each
measurement and the test limits applied. For each measurement, pictorial
examples of setup, method and specification limits are given. These have
been derived from the ETSI and ANSI standards.
