Blocking Characteristics (3G TS 25.141.7.5)
This section explains how to configure your test system, including signal generator
settings and test system connections, in order to complete a blocking characteristics
performance test on your base station (BS). It includes an example performance test
procedure and performance test record.
NOTE An external source capable of providing CW at an amplitude of
−
15 dBm
across a frequency range of 4 to 12.750 GHz is required for testing above
4 GHz (or the maximum RF output frequency of your ESG).
Specification Definition
Blocking characteristic is a measure of the receiver’s ability to receive a wanted signal at
its assigned channel frequency in the presence of an unwanted interferer on frequencies
other than those of the adjacent channels.

Performance Test Objective
The objective of this performance test is to determine the in-band and out-of-band blocking
characteristics performance of your BS 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 specified interferers at in-band and out-of-band frequencies (other than
adjacent channel frequencies).
