    I am looking to extend my diagnostic capabilities and learn more about my car by adding an oscilloscope capability to my PC

    I have seen some propositions on the Internet but would like to benefit from the experience of my fellow BMW owners

    My budget for this is limited (less than €100 for software and interface)

    Does anybody know of a suitable system that would let me check sensor signals on my car ??

    Thanks for your help

    It's a tricky one because a spectrum analyser is only really useful when comparing wave forms.

    The thing is you need to know what you expect to see before what oyu see becomes useful, unless doing really basic measurements in which case a multi meter might well be more useful.

    None of the signals on a car exceed the 1Mhz range and so anything with a sample rate of 20Msample/sec is going to be more than adequate. Also because most signals are digital the analogue capabilty is not essential. Make sure you buy something with good memory and adaptable trigger capabilty, the most important requirement of an osciliscope is the ability to find what you looking for so the trigger capability is really important. As mentioned above a spectrum analyser is also a useful function that some PC based scopes provide with FFT function, they are really useful with an accelerometer for find vibration sources

    Pico scope everytime. PC based and simple(ish) to use. There is even sample waveforms of various sensors on Pico's site.

    I use one all the time at work now, its the best diag tool to use IMO. Just got to scope everything you can to collect a library of waveforms....

    Nice, something I would like to program using JTAG in Ubuntu. Are you a developer?

    TBH I dont really. I would keep your eyes open on Ebay. Sometimes the Bosch PMS100 handheld scopes come up fairly cheap as people dont really know what they are....
