CCDF measurement with WCDMA/HSPA+ signal analyzer

This Over The Air (OTA) measurement has channel scanner, scramble scanner, multipath profile, code

domain power, and route map screens. Scramble scanner displays six scrambling codes and powers

to inform neighbor cells existence and its power. The multipath profile graph helps you to determine

testing area's RF environmental condition. The code domain power shows not only modulation

performance metric but also amplifier capacity and code utilization metric. The amplifier capacity (code

utilization) measurement is an estimate of the amount of power amplifier capacity (code utilization) that

is being used expressed in percent of maximum.
