Autonerdz forums

Hello ,
If is possible please advice and help me ,
I want to buy a four channel automotive scope for use in an independent workshop.
I view on TiePie site a 4 channel differential automotive scope  and at Picotech site I found Picoscope 4 channel non differential automotive scope 
I did not found a comparison on the web between these two automotive scopes but after a web searching Pico seams to be a bit ahead albeit  both seem to be very well made and capable instruments .Which of one must be choosed ?
                                                                                                     thank you very much for your time

I second that!!!!!!!!!!!!!!!!

Not sure what model you were looking at but You could do worse than the Tie Pie ATS5004D. Not bad but no match for Pico.

The differential inputs are no real advantage.  It is not necessary to have differential inputs as long as you are aware of the ground loop potential and ground any and all channels to battery negative.  Then there are no worries.

The Pico 4423 is hundreds of times more powerful than the ATS5004D.  The Pico can collect a hundred million samples on a single screen.  The ATS5004D 512,000.  Also the maximum streaming rate on the ATS5004D is ten thousand samples per second.  The Pico streams at up to 10 million samples per second.  So, in this mode, the Pico would be a thousand times faster.

Plus, PicoScope has some very powerful features like math channels.  I don't know if the ATS5004D software has this.

It appears they do advertise "I/O" channels which look a lot like Maths.

I see their RPM I/O has some cool features that are superior in theory, but I'd have to see it in the real world to decide if I would trust it or not.

They do offer an Ohm's measurement with 3% accuracy, and SureConnect is a nice feature reminiscent of ATS's probe open circuit bias voltage (don't know if that's how it works though). 

The ATIS Pro software is a great idea, but again it is something you would need to see first hand because their demo screenshots are all from one car.  You would need to ask yourself how complete the coverage really is.  Additionally, the scope kit only includes the ATIS lite.  The ATIS Pro software is somewhere around $650 extra.

Speaking of pricing, the TiePie standard kit is somewhere around $2900 USD (using Google's Euro to USD calculator).  Throw in the ATIS Pro software, and the price jumps to approx $3550 USD.  Pico's standard kit is about $2300 USD, and the Autonerdz kit (with all the extra hardware and Picogroup access) is $2350 USD. 

In the specs department, the TiePie isn't too bad, but the 128k buffer isn't even close to Pico.  I did see something that suggested it saves a full buffer before and after a trigger which is a nice feature.  An External trigger is advertised, but I don't know how useful it really is because the details seem sketchy.  They also mention the option of 12 bit, 14 bit, and 16 bit resolutions.  That sounds similar to Pico's resolution enhance feature because they also list the max sample rates at those resolutions.  12 bit gets 50MS, 14 bit gets 3.125MS, 16 bit gets 195.3KS. 

All things considered, you get much more scope for a much better price with the Pico.  And if you can handle the extra shipping and customs from the US, the Pico from Autonerdz is a real bargain.

You need to talk to Tom Roberts Autonerdz when you buy from him no one in the world supplies a better package and support. Join this team you don't get eny better.

X2 on what Karl said .

You're absolutely right, and that's why every release and beta gets a thumbs up or down in the Picogroup section.  I think the Picogroup suggestions forum is a good idea, and we know there are several Pico reps on here that digest what we suggest.

Well, the RPM graph they use is interesting, but I'd want to see it in person because we know the limitations when we do it with Pico.  Ours is more raw, so it might be interesting to see what theirs is like outside a simple 60hz signal.

You would have to educate me on why you would want a duty cycle graph, though.  I suppose I could see some use for it  .

Actually, before this thread, I had no idea there was anyone trying to nip at Pico's heels.  Competition is a good thing, but they're gonna have to step it up to knock out the champ.

Lol!  I forgot that scene.
