Key benefits of envelope tracking include improved efficiency, lower distortion and increased frequency coverage. See how to use 89600 VSA software to understand the impact of envelope tracking on power amplifier performance, measure and display the overall distortion contributed by the ETPA, as well as the timing delay and shaping between the RF and envelope signals, make power added efficiency measurements, and investigate unexpected results by comparing time-aligned versions of measured signals. Watch this video to better understand how, by analyzing the RF and the envelope signals together, you will be able to measure the effects of envelope tracking on power amplifier distortion and efficiency.
