Keysight Technologies Measuring the Burst Time-Gated Power Signal of Wireless Technologies Using Keysight Power Sensors For TDMA, GSM, WiMAXTM, WLAN, and LTE devices Application Brief Introduction Measuring pulse, burst, or modulated signals for wireless technologies such as TDMA, GSM, WLAN, WiMAX, and LTE is very important because it is part of functionality testing and power amplifier module verification during the manufacturing process. High-performance, and average and peak power meters and power sensors are required for measuring the average power and crest factor (peak-to-average ratio) of modulated signals throughout various research and development stages and the manufacturing verification process. To measure the average power of a time-gated pulse or burst signal in a specific timeframe, a lower cost solution is sufficient. As this application note illustrates, the compact Keysight Technologies, Inc. U2000A Series USB power sensor is a low cost solution for measuring the average and time-gated average power of burst signals. The Keysight U2020 X-Series USB peak and average power sensor is a high performance USB power sensor with additional 30 MHz video bandwidth capability for measuring average, peak, and peak-to-average power burst signal. Both USB power sensors series allow the power measurement to be displayed on a PC and provide the same functionality and performance as conventional average power and peak power meters and sensors. In this paper, we pick one of the wireless technologies; timeslot burst structure signal, GSM (Global System for Mobile communication) for reviewing. This application note applies to the following products from Keysight
