1. A method for measuring power amplification functions, comprising a first mode that includes:
- providing a first signal at a predetermined first frequency (F1) to an input of a device under test, wherein the first signal is provided by a measurement interface apparatus;
receiving a harmonics signal at the measurement interface apparatus from an output of the device under test;
passing the harmonics signal through an input port of a main-line of a first air-line directional coupler disposed within the measurement interface apparatus; and
providing the harmonics signal from an output port of the main-line of the first air-line directional coupler to a spectrum analyzer coupled to the measurement interface apparatus.

Abstract
An apparatus includes a device under test, a network analyzer, an internal amplifier, a first switch, a second switch, a third switch, a first air-line directional coupler, and a first attenuator. A method of characterization measurement includes providing a harmonics signal from the device under test to a spectrum analyzer, providing a generated signal and a reflected signal to a first receiver disposed within a network analyzer, and recording a parameter deviation of the network analyzer.
