This series of videos talk about Power Amplifier (PA) measurement with Digital Pre-distortion (DPD) and Envelope Tracking (ET) technology using Keysight's PathWave X-Series N9055EM0E Power Amplifier Measurement Applications and PXIe VXT transceiver. This part 6 video introduces you to the new DPD approach called Iterative Learning Control (ILC) DPD which allows the modeling of any memory effect without increasing the complexity. It also shows a live demo of measuring PA performance with ILC DPD by using a 5G NR signal.
