Real-time cdma2000 personality
(Option 201, ESG-DP and ESG-D series only)
Description
Option 201, cdma2000 personality, adds a flexible solution for
cdma2000 mobile and base station test to Agilent ESG-D and ESG-DP
(high spectral purity) series RF signal generators. Option 201 is a
firmware personality that requires Option UN8, (hardware revision
C or greater), real-time baseband generator to be installed in the
ESG. The fully coded nature of this solution in both forward and
reverse mode supports long and short codes, cyclic redundancy
checks, convolutional or turbo encoding, interleaving, power con-
trol, and complex scrambling. Additional capabilities allow flexible
channel configurations with individually adjustable power levels
and data rates, customizable user data, and variable chip rates.
The option is backwards compatible with IS–95A, in both the base
station and mobile simulation modes, through support of radio
configuration 1 and 2.
