This video shows how to measure the distortions caused by an amplifier under test. A digitally modulated signal is fed into an amplifier and then captured by a signal and spectrum analyzer. Key parameters such as EVM and the AM-AM curve are measured and the compensating effect of digital predistortion is shown.
