W-CDMA personality

(Option 200, ESG-DP and ESG-D series only)

Description

Option 200 W-CDMA personality adds a flexible solution for
W-CDMA mobile and base station test to Agilent ESG-D and ESG-
DP (high spectral purity) series RF signal generators. Signals are
fully coded in both forward and reverse links to provide complete
testing of receivers.

Channel types generated

Primary Synchronization (PSCH), Secondary Synchronization
(SSCH), Primary Common Control (P-CCPCH), Common Pilot
(CPICH), Dedicated Physical (DPCH), Page Indication (PICH),
Orthogonal Channel Noise Source (OCNS), Dedicated Physical
Control Channel (DPCCH), Dedicated Physical Data Channel (DPDCH)
