Adjacent Channel Power for 3GPP FDD
The equipment layout for 3GPP FDD signal generation includes the options R&S B13 (Baseband Main
Module), R&S B10 (Baseband Generator) and R&S K42 (Digital Standard 3GPP FDD).
Test equipment Signal analyzer R&S FSQ including option R&S FSQ-K70
(Vector Signal Analysis) (table 1-1, pos. 24)
Test setup
 Connect signal analyzer to RF output of DUT.
Test method Set standard 3GPP FDD in the baseband. Perform the measurements
with the 3GPP measurement setting of the R&S FSQ.
Measurement  Settings on DUT
Level: max. level, refer to data sheet (depending on options)
