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)
Signal generator (Table 1-1, item 5)
Test setup
Connect signal generator’s I/Q-outputs to I/Q-inputs of DUT
.
C
onnect signal analyzer to RF output of DUT.
Test method Set standard 3GPP FDD in the baseband of the signal generator and feed
the I/Q signal into the DUT’s I/Q-inputs. Perform the measurements with
the 3GPP measurement setting of the R&S FSQ.

Test results should not miss the typical values by more than 4 dB.
The measurement has to be carried out for each RF path installed in the DUT.
