Note 1: W-CDMA (Modulation Set-up for ACPR Mode); The Baseband I and Q input signals were generated using “Test Model 1 with 64 channels”
settings in the Agilent E3844C.
Note 2: The I/Q baseband amplitude and phase inputs were offset to achieve Sideband Rejection (SBR) levels. LO = +6 dBm, SSB Power = 0 dBm
