WCDMA Adjacent Channel Power

(Option 400)

This automated test measures the ratio of energy in the offset channel to the overall energy in the main

channel. Energy in the main channel is measured with RF power on and with RF power off. Energy in the

adjacent and alternate channels is measured with RF power on and is corrected for the spectrum analyzer’s

noise floor; the spectrum analyzer’s noise floor is determined when measuring energy in the main channel

with RF power off. The Option K35 WCDMA test set increases the spectrum analyzer dynamic range so it is

capable of making the measurement.

Recommended Equipment

• Agilent 8563EC Option K35 spectrum analyzer

• Agilent Option K35 WCDMA test set
