Dr Jonas Urbonas provides an overview of fully-active harmonic vector receiver load pull using IVCAD and a 4-source ZNA.

He starts with explaining the motivation and challenges, proceeds to introduce a turnkey solution to solve these challenges, and then provides a quick demonstration of fully-active harmonic load pull, using active tuning to hold the 2nd and 3rd harmonic load impedances at their ideal match condition, and sweeping the fundamental impedance, while performing a gain compression power sweep.
