I have a PICO 3423 and I'm trying to capture compression waveforms using a Fluke PV350. I've made several custom probe "drivers" for it but I just can't seem to get decent waveforms. I've change the filtering all over the place, I had some time & a vehicle in a week ago, I was sampling off one cylinder with the engine running and tried for an hour and a half, never could get a good/usable waveform. The guys at AES wave sent me a couple "drivers" (custom probe settings), but they don't do the trick either.
Has anyone tried compression waveform analysis with this setup before? Did I get a bum PV350? I'm using PICO 6.something and the scope seems to work fine, I get good waveforms with other devices.
Any help from anyone would be greatly appreciated. I've got a pressure waveform analysis class coming up in Sept and would like to get the most out of it..... Thank You Tom Berner, Ada Auto Repair 208.323.7242
