1. A method for determining an input operating point and an output operating point on a non-linear traveling wave tube amplifier (TWTA), comprising:
- measuring non-linearity of the TWTA;
computing an input root-mean-square (RMS) value of an input signal used to measure the non-linearity of the TWTA, wherein the input RMS value identifies an input operating point of the measured non-linearity of the TWTA; and
obtaining an output operating point.

Abstract
A method, apparatus, article of manufacture, and a memory structure provide the ability to determine an input operating point and an output operating point on a non-linear traveling wave tube amplifier (TWTA). The non-linearity of the TWTA is measured. An input roots mean-square (RMS) value of an input signal used to measure the non-linearity of the TWTA is computed. The RMS value identifies an input operating point of the measured non-linearity of the TWTA. Lastly, an output operating point is obtained.
