7 TAS5600 Universal Interference Emulator
TAS5600 provides all
the applicable
WCDMA Uplink and
Downlink channels.
This is a Code Domain
plot for a WCDMA
Downlink Channel.
To effectively address the testing
requirement of UMTS UEs and Node-
Bs, the TAS5600 provides extremely
accurate and realistic interference
generation. All required interferer types,
such as uplink and downlink WCDMA,
GSM, AWGN, and CW are included. The
format of the WCDMA modulated
interferer is defined in the appropriate
3GPP downlink (TS 34.121 and TS 34.122) and uplink (TS 25.141 and TS
25.142) specifications. Each WCDMA
interference signal within the TAS5600
is comprised of multiple downlink or
uplink channels. These channels are
then modulated on to an RF carrier at
the desired interference frequency
using a scrambling code provided by
the user. Wide Range of UMTS Interferers
The 5600 provides GSM
Interferers with Optional
Fading as specified in 3GPP
TS 51.010-1 Section 3.6.1.
The GSM modulated interferer allows
verification of adjacent channel receiver
performance in the presence of a
second GSM channel. This is an ideal
tool for manufacturers who want to test
dual-mode UMTS UEs. The GSM modulated interferer provides a GMSK
modulated carrier with optional fading.
The interferer meets UMTS testing
standards as defined in 3GPP TS
51.010-1 Section 3.6.1 and Annex A5.2
for uplink and downlink testing. GSM Modulated Interferers
