Hi gbgunn-st, I have attached some examples of CAN 500 capture with decoding, it is not J1939 as I do not come across commercial vehicles, however the scoping and decoding is not much different. (This was captured with x10 300Mhz probes, but ordinary leads will be just fine) I think it is good examp...

Hi, it is due to short time capture per one screen. The frames will be red in decoding table simply because part of the frame is missing (continue beyond the screen) Set the time to at least 50ms/division and sample rate 5Ms/second. Then use zoom to see details. If you want, I will post here capture...

I would like to jump into this topic, picowight has good workaround technique that works well if you are present next to the laptop at the time of the event of interest. But I would still call it as workaround and I hope this could be solved somehow. Ideally the frames won't have any gap between or ...

Hi hbr, I have attached the file with RPM. Your capture was good quality and you have recorded long time 1 sec/div which is important in crank signal. I have saved it with PS7 EA 7.1.15 It is always good to use latest version of the PS7, in case you did not update and used some older version? Hope i...

Hi Michal, As Ben says, this forum is excellent source of information and learning material. Anyway, it's great to have Slovakian Pico user here. I wonder how many automotive picoscope users are in our countries as I am also originally from Czechoslovakia, Czech Republic. It could be good idea to ge...

Hi Tiblu, Please take my comment as generic only, I don't touch US or Japanese cars which are using inductive sensors, but some our European cars have them also. So here is my comment, hope it helps or give you new ideas. When you have intermittent circuit fault, you should record longer time base, ...

Hi GGS,
This is interesting, it could be helpful to others in this forum.
Would you have some .psdata files to share with us? Like before with bad ECU and fixed with new ECU for example?
If so, please upload.
Thank you for update.

Roman

I have attached link to one file from NVH practical training. This car had noisy rear diff and there was necessary to prove it as part of diagnostic process. It is not exactly the tyre and wheel bearing noise question but it may also provide some direction and answers on Pico NVH capability. There a...

Hi autoairsteer, I have tried this and my answer is YES, however you may need to have some saved .pddata files to help you with the identification. Ideally if you will have a car with really faulty wheel bearing, then you will have something to compare (against the same vehicle model). The bearing w...

Hi brucestafo,
Thank you for the update, I will personally benefit from your info, going to test on my other laptop with low UPB current output.
