    What is your price range? Also, what type of PicoScope were you using? Obviously saying you had a PicoScope is a bit like saying you had a Volkswagen

    There's a vast range of oscilloscopes, from dedicated devices (I'm priviledged to have access to a Tektronix Mixed Domain DSO at work - circa £2,500) to Pico type 'interfaces' that attach to your computer.

    If you like the form factor of Pico devices, howsabout the Pico 2204A? A 2-channel device, 10Mz, should be quick enough to see if a LIN sensor is transmitting or checking the duty/dwell factor of injectors etc. Lots of functionality for not a lot of money.

    From RS Components Browse through the others and you may find something affordable.

    Are you specifically after a PC Software based scope? If not then it is well worth considering one of the "proper" entry level scopes. I've got a Rigol DS1054Z which is a 4 channel 50MHz scope and is very popular amongst EE hobbyists. The DS1054Z is easily hacked to be the same as the DS1104Z (100MHz) which is done via the firmware and this is what I have done with mine. It really is a nice bit of kit for not a lot of money in the scope world and any captured data can be saved and downloaded to a PC for analysis using PC software. Price point is around 300 GBP so only the same sort of cost as one of the original HEX-USB+CAN cables.

    These are a couple of my videos showing it in action which will give you a basic idea of what they are like:-

    All 4 channels in use:

    I suppose that I'd rather a kit to use with my lap top .. And slso 2 Chanel would do but I'd like to have the option of scoping drive CAN if I had to ect .. 200-300 I hoped I could find something

    OK, in that case I think I would probably be inclined to give the lower end PicoScope models a miss due to their limited specs and performance. If I was going to buy a USB scope I would probably take a punt on one of the 6000BE series Hanteks. There are a number of them in the range starting at the cheapest 20MHz model (the 6022BE @ ~50 GBP) going all the way up to the most expensive 200MHz model (the 6212BE @ ~250 GBP). They do seem to get mixed reviews but at the end of the day you get what you pay for and if you look at equivalent PicoScope models you will be paying anything from ~600 GBP upwards.

    Like you, my original intention was to get a PC based scope for portability and ease of use but after many weeks of research I finally decided to bin the idea of a PC scope and to just get a decent hobbyist bench scope instead. While I have no hands-on experience of using a PC based scope, I do feel that going for a bench scope over a PC based one was probably one of the best decisions I have made.

    The following EEVblog video is quite a few years old now but some of the the points are still relevant today, so just something to keep in the mind when choosing a PC based scope:-



    And if you're interested in part 1 of that video which is just a general digital storage oscilloscope tutorial, you can find it HERE.

    Ha, we got Shaun a Rigol scope as well. I think he's also got a USB one, but I'm not sure which.

    AutoDitex do a couple of cheap entry level car scopes. They also do probes - like the Pico ones but far cheaper. Not as good as Pico by any stretch but for the money...

    Hunt for a used automotive picoscope. You will regret buying any others.

    Ive got a non-automotive pico (2 channel) and a Hantek DSO-3064 kit V (4 Channel).

    The pico software is far easier to use and but at over 5 times the price of the hantek I couldnt justify the price.
    The other thing is the hantek uses a seperate power supply (Pico uses USB)
    Ive not found anything the hantek cant do compared the pico yet it sometimes take a fraction longer.

    If your using the scope day in and out (or want the pressure sender/ NVH kit)- then the pico would be your choice
    For me where it gets used once a week as a general scope the hantek does just fine.
