摘要（英）：

The invention discloses a method for synthesizing mixed signals on a single transmission path. The method includes the following steps: generating a sinusoidal voltage signal by a sinusoidal signal source, and generating a sinusoidal current signal in a coupling manner after the sinusoidal voltage signal is input to an excitation sensor, wherein the sinusoidal current signal is injected into a measurement loop; injecting a pulse signal into the measurement loop by a pulse signal source; and mixing the sinusoidal current signal and the pulse signal in the measurement loop to generate a mixed signal. The technical scheme of the invention proposes a synthesis loop method of the sinusoidal signal and the pulse signal, the mixed signal of a high frequency sinusoidal signal and a discharge pulsesignal can be generated on the single transmission path, and therefore, detection is performed on the anti-interference performance of the test instrument with the excitation signal as a partial discharge of the high frequency current method.
