How to use a scope for noise and vibration testing

In this video I show a simple but effective method of how to be able to hook up chassis ears to the scope and capture on a waveform noises as well as vibrations

Was just about to drop 400 on wirelesss chassis esrs because inused them in the past and they definitely come in handy....but i already got an 8 channel scope so just getting the leads now thanks!

Man, I can’t tank you enough for this … I have issues sometimes finding certain noises on suspensions but with this tool I think it will help me to pinpoint where they come from . I have in my arsenal the wireless chassis ear but sometimes it does not help .

I have a 2 channel PicoScope and a really nice MicSig 4 channel oscilloscope tablet. Recently I came across info on the Chassis ear, and got their wired kit and their wireless (not bluetooth) kit as well. Once I began to use them I (also) began to think of how to connect the scopes to the sound clamp circuits to be able to visually see the noise patterns. I came across your video in advance of trying to connect the scopes to the Chassis Ear units, likely saving me a little trial and error effort. Many thanks! I am well retired now, but I sure wish I had known about the Chassis Ear units back in the 70s ands 80s, with or without a scope interface.

Excellent presentation. Many Thanks!

Love your videos and how you explain how and why things work. Thank you

IIRC, the wireless Chassis ear mics have a RCA(phono) plug on the cord. An audio phono cord and phono/BNC adapter would allow connecting directly to the scope. The elements (piezo disc) are the same wired or wireless.

thanks! i had made a quick connect lead for the BNC to a mic female and had it wired wrong. sensor wouldnt pickup anything.

Can you explain on thr clamp side how you have positive and negative connected? I assume thr clamp is positive but how is ground connected on the clamp side?

i like you way .what about wheel bearing noise .i was thinking doing it with pieso elec sensor
