Abstract
The problems and phenomena in the harmonic level measurement of transmitter are presented. After analyzing the working principle of spectrum analyzer, based on the polynomial nonlinear model of mixer, the influence caused by the nonlinear response of the spectrum analyzer on the harmonic level measurement is studied. The prediction model of the influence degree is given. And according to the engineering requirement of harmonic level measurement, a method of harmonic level measurement for transmitter is presented.
