ESG Family Signal Generators Using Functions
Option 200 3GPP W-CDMA Base Station Performance Testing
Adjacent Channel Selectivity (3G TS 25.141.7.4)
This section explains how to configure your test system, including signal generator
settings and test system connections, in order to complete an adjacent channel selectivity
performance test on your base station (BS). It includes an example performance test
procedure and performance test record.
Specification Definition
Adjacent Channel Selectivity (ACS) is a measure of a receiver’s ability to receive a wanted
signal at its assigned frequency in the presence of an adjacent channel signal at a given
frequency offset from the center frequency of the assigned channel.

Performance Test Objective
The objective of this performance test is to determine the ACS performance of your base
station against limitations described in the 3GPP W-CDMA RF specification (3G TS 25.141
V3.4).
Defining Measurement
The PASS/FAIL status of the DUT is determined by measuring Bit Error Ratio (BER) in
the presence of a specified adjacent channel interferer.
Process

Base station conformance testing (FDD) Technical Specification 3G TS 25.141 V3.4 (2000-12).
