W-CDMA Dynamic Power Analysis Using the 8960

Application Notes

Dynamic Power Analysis Measurement Overview

The dynamic power analysis measurement is a flexible tool that allows the measurement of UE output power sequences that step up and/or down with varying or fixed power step sizes. The power step length, which must be fixed for the sequence, can be between

100 μs and 10 ms. A total of 58.26 ms of power sequence can be analyzed. For example, up to 87 steps can be measured when Step Length is set to one timeslot (666.7 μs). The test set can measure power between –61 and +28 dBm, and a total change in power of up to 25 dB.

To use the measurement, Measurement Frequency must be set to the expected UE transmitter frequency, and Manual Power must be set to the maximum expected power for the sequence. Next, specify the length and number of steps in the sequence (including trigger pulses), then configure the RF rise trigger, initiate the measurement, and order the UE to send its sequence continuously.
