Man thanks for your answer and i understand your point, i have other question, in your opinión  the fluke 98 automotive is a good choice for work in New cars? Or maybe with other model can make more? I have a fluke 97v and with this can check eléctrica wiring, and have a scanner launch for read codes, but with the sensors need a tool like a oscilloscope but want a good chice. Thanks for answer

The Fluke 98 was excellent and sorely needed when it came out 25+ years ago--and it was discontinued due to the lack of availability of one of the chips (made by Phillips) not due to it no longer being useful.  I prefer it to the ones from automotive test tool companies because those to me are "dumbed down", a way for mechanics with some electronics knowledge to quickly do specific diagnostic tests for common problems.  So if you have an electronics background and you do want a scope for automotive work, I'm not aware of anything better.  However, as the on-board diagnostic capabilities have gotten better and better over the years, I see less and less need for scopes.  Imagine working on a complex body control module (say a 1990 BMW 750iL) that has some odd problem but has absolutely no scan data or any other window into its operation--just the inputs and outputs.  You think it is defective, but it is a special order part and costs several thousand dollars!  Well, lets just say a scope is real handy in that situation.  But the equivalent car 25 years newer has extensive data that gives you a big window in--often telling you the voltages on the inputs and outputs and even validating internal and external circuits.

So, if you need a scope, the Fluke 98 (either series) with all the original leads and accessories, is still a good choice, although it does have its limitations.  I'm not sure how much you need one though!

Man thanks for your complete answer, i not work with bmw, o with old cars, but need watch some ckp sensors or o2 sensor, and sometimes in the scan tool cant read, and think with a oscilloscope can make a Best work, but maybe if i can make this readings with a other scope i preffer buy other scope more común. Thanks thanks thanks
