Abstract

The cost is too high when measuring short-time and frequency-conversion Interference signals with the electromagnetic interference (EMI) receiver. To solve this problem, this paper presented a novel measurement method base on time-frequency domain transformation. The time domain waveform of the interference signal is firstly obtained by measurement detector and oscilloscope, and then the frequency spectrum of the captured waveform is analyzed based on time-frequency domain transformation. The experiment result indicates that the result get by the measurement method presented in this paper match well with the result tested by the EMI receiver.

Key words： Electromagnetic interference frequency spectrum measurement method short-time and frequency-conversion time-frequency domain transformation
