Adjacent Channel Power for 3GPP FDD
The equipment layout for 3GPP FDD signal generation includes the options R&S SMU-B13 (Baseband
Main Module), R&S
SMU-B9/10/11 (Baseband Generator) and R&S SMU-K42 (Digital Standard 3GPP
FDD).
Test equipment
- See section
See section „Test Assembly for Measurement realized
RF Evaluation“ on page 1.2
- Signal analyzer R&S FSQ including option R&S FSQ-K70
(Vector Signal Analysis) (table 1-1, pos. 24)
- Signal generator if no
R&S SMU-B10 (Baseband Generator)
is installed
Test setup
Connect the DUT I/Q-outputs to the I/Q-inputs of the signal
generator
Connect the signal analyzer to the RF output of the signal
Generator
.
Test method Set standard 3GPP FDD in the baseband. Perform the measurements
with the 3GPP measurement setting of the R&S FSQ.
