Research on Test Method of Transient DisturbanceAbstract:For fixing on the coupling disturbance waveform of the signal circuit well and truly, using oscillograph directly to measure the waveform is the best intuitionistic test method. But the transient disturbance rises fast including much high frequency energy. And the high frequency parts can emit through the space. The test results become suspect. This paper offers a few items for the configuration of the oscillograph and the connection lines of the single-ended probe ＆ differential probe. Following the configuration rules, we achieved satisfying test results with the two test methods.[著者文摘]
