Real-time 3GPP
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.
