Blocking Characteristics (3G TS 25.101.7.6)
This section explains how to complete a blocking characteristics performance test on your
user equipment (UE). It includes a process definition, signal generator configurations, test
system connections, abbreviations, an example 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 band 3 out-of-band
performance testing above 4 GHz (or the maximum RF output frequency of
your ESG).
Specification Definition
The blocking characteristic is a measure of the receiver’s ability to receive a desired signal
at its assigned channel frequency in the presence of an undesired interferer on frequencies
other than those of the spurious response or the adjacent channels, without this undesired
input signal causing receiver performance degradation beyond a specified limit.

Performance Test Objective
The objective of this performance test is to determine the in-band and out-of-band blocking
characteristic performance of your UE against limitations described in the 3GPP W-CDMA
RF specification (3G TS 25.101 V3.3).
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
spurious response or adjacent channel frequencies).
