3GPP Receiver Tests Under

Fading Conditions with

R&S

CMU200 and R&S

SMIQ

This application note describes how to generate 3GPP (UTRA-FDD) signals for receiver tests under fading

conditions for user equipment. The test setup requires an R&S

CMU200 Universal Radio Communication

Tester with option R&S

CMU-B17 IQ-IF interface and an R&S

SMIQ Vector Signal Generator. The test

setup can be calibrated with either a R&S

NRP-Zx USB power sensor or an NRP, NRVD, or NRVS Power

Meter. To calibrate the baseband and RF path and configure performance tests according to the 3GPP test

specification 34.121 easily, the program 3GFadLevCor is included.
