Wei and Weifeng, Please check this out and add it to any report on resonance scanning. I = would be happy if I can have a report on resonance scanning: Method Probe some results by Wednesday in Korea, as I wanted to present the results Thursday to = Huawei. David Pommerenke -----Urspr=FCngliche Nachricht----- Von: si-list-bounce@xxxxxxxxxxxxx im Auftrag von Doug Smith Gesendet: Sa 11/3/2007 6:47 An: emc-pstc; SI-List Betreff: [SI-LIST] measuring structural resonances using an oscilloscope =20 =20 Hi All, I just posted my latest Technical Tidbit for November; Measuring Structural Resonances in the Time Domain - Part 1=20 The method of measuring structural resonances uses an oscilloscope, a = pulse generator, and a pair of loops.=20 Abstract: Oscilloscopes are more common in most engineering labs than networkanalyzers or spectrum analyzers, so measurement methods that use oscilloscopes maximize the return on lab equipment for many companies. A method of measuring structural resonances using an inexpensive pulse generator and an oscilloscope is described and results are presented.=20 The link to the article is the picture of the experimental setup at the bottom of the main page at http://emcesd.com[1] .
