Title: more channels for automotive Post by fordman on Mar 10th, 2015 at 6:47pm
just asking if anybody else sees a need for more channels.
as he new vehicles have dohc with sensors for each cam and when you add crank there is 5 channels,that is if you want a sync with cams and crank. I wonder if pico will make a 6 or 8 channel automotive scope |
Title: Re: more channels for automotive Post by crackerclicker on Mar 11th, 2015 at 7:14pm
Don't know if that will ever happen, but I'll give you a hint for when you need more than four channels on a CMP-CKP capture. Two words: Reference Waveforms. ;)

Sometimes I could use more channels but usually can do without.
This question has been aswered in PicoScope forum. http://www.picoauto.com/support/post32215.html#p32215 |
Title: Re: more channels for automotive Post by fordman on Mar 12th, 2015 at 2:45pm
most of the time 4 is plenty but with the new vehicles with
more cam timing sensors it would be nice to sync all on one timed screen did not mean to beat a dead horse with this just thinking down the road. |

Running two automotive scopes, one with a regular release and one with a beta release it is possible to have eight automotive channels.
The only way they will be truly synched would be something that could be captured by a single trigger for both. Might be a good reason to pick up one of the new independent ground auto scopes. ;) I am not there yet, but I bet I will be soon. :) Sam |

Yep, I've got my eye on a new setup for sure also. |
Title: Re: more channels for automotive Post by crackerclicker on Mar 14th, 2015 at 2:01am
I dunno. If I ever get to the point where I NEED, on a regular basis, more than 4 channels, I'll hope & pray Pico has developed an automotive 8 channel tool. Otherwise, ATS would get my business, and most of you know how I feel about ATS's use of computer screen real estate. :(

John Thorton was running a 8 channel picoscope last weekend at Vision on a live car in class. Someone said it was to retail at $3200.00 and it wasn't out yet.

Did you take pictures? what was he capturing? |
Title: Re: more channels for automotive Post by Mike in St. Louis on Mar 14th, 2015 at 3:31pm
Hi Mick. He was capturing. He had a new Chrysler and a New Ford with exhaust hoses on them ran outside the building. I didn't get any pictures, but it was damn impressive. I walked in at the very tail end of his class because I left early out of my class.

a birdy told me it was Scot Mana's 8 channel scope and they were scoping vvt systems with it. or so I've heard.

Sorry about that, it was a VVT class. Whose scope? That I don't know.

Title: Re: more channels for automotive Post by PRESTON on Mar 15th, 2015 at 9:16am
Yeah, that's BS if we haven't heard of it here first.

I suspect what was seen was a 4824. There is no Automotive 8 channel. That does not mean you could not use the 4824 test and measurement scope for automotive. However this would be for the experienced only. Things to consider: The 4824 does not work with the automotive software. But you can customize the test and measurement software with automotive probes, etc. The 4824 has no thermal fuse protection. Grounds are common and any accident there with a ground loop would be fatal should you short circuit something. Not a problem as long as you remember the 'ground' rules and don't do anything reckless. The 4824 has a 50v max input. This means that you would not want to forget an attenuator on any circuit with a high voltage kick like ignition primary or damage could easily result. That being said, it's an awesome scope. In the right hands, it wold be a very powerful diagnostic tool. We had a couple of requests for one and so we did put together a 4824 kit of sorts. Then these individuals changed their mind. So, we still have them and they are on our sale page with special pricing: http://www.autonerdz.com/4824.html These do not come bundled with a Picogroup subscription but that would not matter to those who already are members. We only have two and will not be ordering any more for stock. We can special order but the cost would be a lot higher. So, if anyone want one...... |
Title: Re: more channels for automotive Post by PRESTON on Mar 16th, 2015 at 9:09am
Yes, I should have been more specific, I was aware of that one, I should have said 8 channel automotive scope. Thanks for pointing that out Tom.

Title: Re: more channels for automotive Post by Brian Haley on Mar 16th, 2015 at 9:21am
I think the 4824 would be fine for anyone with a little Pico experience, keep the grounds on battery - and know when to use attenuators.
There's an example capture in my folder on the drop site. |

The double software, as I understand only applies to two of the same model. Without going into a ton of detail out of the Picogroup keep in mind running multiple scopes is intensive on a PC so don't do it on a low resource pc. I have successfully ran up to three Pico's at once. I think I showed that on the Ford Contour thread in the pigogroup general discussion. Sam |

Sam. I will PM you on this as to keep it out the general public ;) |
Title: Re: more channels for automotive Post by sneaky pete on Mar 16th, 2015 at 10:16pm
I enquired to Tom and Brian about one. great looking scope but with my luck, first time I would use it I'd forget an attenuator and fry it. Hopefully one day they make it automotive ready but I had to hold off at this time.

If you want a whole bunch of channels check this out.
You can write your own software and use this function to hook up 64 PicoScopes I found this in the PicoScope Application Programmers Interface. 4.9 Combining several oscilloscopes It is possible to collect data using up to 64 PicoScope 4000 Series PC Oscilloscopes at the same time, depending on the capabilities of the PC. Each oscilloscope must be connected to a separate USB port. The ps4000OpenUnit function returns a handle to an oscilloscope. All the other functions require this handle for oscilloscope identification. Note: It is not possible to synchronise the collection of data between oscilloscopes that are being used in combination.

If anyone is still interested, Scot Manna is the proud owner of the non-automotive 8ch Pico, and he shared some captures of GDI injectors in class. As Tom said, Scot was using the non-auto Pico 6 for those captures. Unfortunately, the class manual was poorly made with drastically small pictures, so I didn't even bother to ask him if the images could be shared. |
Title: Re: more channels for automotive Post by Tom Roberts on Apr 25th, 2015 at 8:02am If anyone wants one of these 4824 kits, let us know. If they don't move soon, we plan to send them back to Pico. |
Title: Re: more channels for automotive Post by PRESTON on Apr 25th, 2015 at 8:33am
Hey Tom, if it's taking up too much space at your place I'd be happy to "store" it for you until someone purchases it ;)

Title: Re: more channels for automotive Post by autosparky on Jul 20th, 2015 at 2:33am
recently had the need to diagnose 2 cars both with intermittent problems that needed hours of run time, buying another Pico and laptop would of helped me, but got me thinking this would be a better option than buying an 8 channel job - that's if the software could somehow synchronize both units.
The chatter over at Pico forums is that the need for 6-8 channel is very low for the automotive market so it wont happen, so Pico if you're listening, how about making an effort to develop a special brew of software to combine 2 or more scope units what do you other nerdz think? |

That's on the wish list.... ;) If the Pico team cold pull that off it would be awesome. |
Title: Re: more channels for automotive Post by autosparky on Jul 22nd, 2015 at 2:33am
just had a thought [smiley=idea.gif]
if anyone can remember (I think) version 5, every screen had the computer time so as we scrolled through the WF it showed the real time of the capture. Now if this could be done again, we can save one pattern as a reference then line it up against another running scope ( not sure if I explained that right?) |

Yeah. That's currently possible to adjust the delay on a reference waveform to sync up with another capture. Here is a CKP from two different scopes running at the same time. One is a reference with a delay so they overlay perfectly. |

Tom I think another picture with them split apart a bit might help explain what you are saying. You have it lined up so great it looks like only one trace is there. |

Here ya go. This is a capture we viewed in last month's Group Therapy when we were discussing floating ground VRS capture techniques. File available in our cloud Group Therapy folder 06_18_2015/EDIS CKP Shorted. This is actually a math channel from one capture and a CKP ref from another. I would attach the file but not in the Public boards.... |
