3 terminology and units of measurement

Peak code domain error (PCDE). The error vector power by mapping to a specific spreading factor code domain, code domain error on each codeword is the codeword Mapping the average power and the complex plane reference waveforms to average power ratio, and expressed in dB. Peak code domain error is that all code Code domain error word in the maximum. The measurement interval is one timeslot.

4 Overview

WCDMA tester by reference crystal oscillator, RF signal generator, WCDMA signal generator, RF Power Analyzer, WCDMA analyzers, audio signal generator, audio analyzer and spectrum analyzer functions etc. Can Comprehensive test instrument module configuration, mainly for the production, development and testing WCDMA terminal or base station equipment.
