Load-pull is the colloquial term applied to the process of systematically varying the impedance presented to a device under test (DUT), most often a transistor, to assess its performance and the associated conditions to deliver that performance in a network. While load-pull itself implies impedance variation at the load port, impedance can also be varied at any of the ports of the DUT, most often at the source.
