I've checked the pico website ... A basic kit is priced some $1,300 ... Not for a diyer, but oh how i would love to have one! For now i would just contend my self with an ac/dc clampmeter with analog output for my analog oscilloscope

i've actually been visiting pico website in the past ... They started with simple a/d converters for the pc, basically turning the pc into a digital oscilloscope ... I knew they have promising products ... And here it is
it's good to have one specially if you do volume diagnostics

you will be able to analyze the result frame by frame precisely.

It will pay for itself

i used to have analog testers but i traded most of them
and there is still one left but it's been parked in my house a few years now.

If you are interested of some more latest tools and equipment

just let me know and i will e mail it to you how to build it .

Or some latest techniques that i can share ( e mail only)

i built one of my prized testers myself and alot of independent garages are coming in my shop to get the problem cars diagnosed
