f you want your Pico to operate like the Snap-on offerings with a continuous single scrolling buffer, the solution is very simple. In streaming mode, set a repeat trigger on the right edge of the screen at a voltage level that will never be met by the signal being tested or trigger off a channel that is not being used- done. Now use the space bar to stop the scope when the event occurs.

Hi Brian,

I have been using that technique for some time now and find it very useful.  As far as I know, it's inception was at Vision a couple years ago in Matt Faslow's Pico scope class.

Thanks Brian.
Pico is new to me, so it's a great tip to get as a newbee like me.
Keep up the good work, and keep the tips flow... Smiley

We don't usually post PicoScope tips and techniques on the public boards like this but, in this case, it seemed appropriate to post it here in this discussion.  Seems the 'Pico Gap' fantasy has a life of it's own even though it has no basis in reality.

We just thought that this would serve as another 'Myth Buster' for those that seek the truth.   Wink

It's good that Matt and others are sharing this tip as well.  Since Matt Started his PicoScope journey with Autonerdz, he has sure come a long way.   Smiley

There are plenty more great tips and techniques available to Autonerdz Picogroup members.  Since we introduced PicoScope to the automotive industry in North America, we have grown the largest and greatest PicoScope automotive user's group in the world. 

Thanks for dropping by.   Smiley

You got that right, Tom. It seems there are a few that like to bring this up now and again. Its ironic this was brought up again. I went to lunch with a very good technician friend of mine yesterday and he had brought this up. He also recognized the one who is doing it the most. Both of us have already spoke our minds on this and we'll just have to let it die or let it ride. I'm not sure what else we can do.

What do you mean "fantasy" ??

It is not a fantasy it is reality, So the PICO has some flaw's.

All scope's have flaw's.

Get over it  Smiley

I have

Although it would be nice if they addressed issues with the software instead of adding more bells and whistles.

Paul,

I refer you back to Brian's post in this thread.

If anyone really wanted their Pico to run a single continuous scrolling buffer, like the Snappy offerings, then just do it.  The only difference is that you can achieve much better samples per second over much longer capture times using a Pico.  Using this method the facts speak for themselves.  There is no 'Pico Gap'.

We could, of course, have a discussion about the advantages vs disadvantages of doing this.

However, I don't see how you can maintain that the 'Pico Gap' is reality when the facts clearly don't support that.

Maybe you can explain this to me.   Huh

I agree - when using this method there is no gap.

That is why I often use it.

It certainly is not perfect but I do use it.

Paul,

Get over it


There is nothing for me to get over. The chance of me missing something with my Modis is much greater than using the PicoScope. Do you think that I don't know how to use either one? The thought of having to run an SO scope zoomed in to prevent aliasing is increasing my chances to let some signal scroll by without seeing it. What is worse is having it scroll out of the buffer to never see it again. You guys can praise that scope all you want, but I'll continue to use the Modis as a scanner only. I don't have to worry about that with PicoScope. Plus, I get more than one full buffer if I want. That is where the gaps come from. Big deal. What percentage of acquistion do you think I'm missing in streaming mode? Very little. Some of you make this out to be more of an issue than it really is.

I've not had a single example to share where I've missed something critical in the "gap." Do you?

Hi Brian,

Great Tip!!

Matt Fanslow showed that to some of us a couple years ago. He also demonstrated that last year at the Vision conference.

Where you in that class?

Is that where you saw it?


Hey Paul,
I don't think Brian would spend much time in Matt Fanslow's classes  Grin

Hi Paul,
I hear what your saying. I said a similar comment myself not too long ago about some software. The basic functions should be right before adding other 'stuff'.
If the issue you are referring to is this 'gap', and removing it. It's not possible. There must be some delay as the buffer is written to the memory. I like picos bells and whistles.  Smiley

I am putting this on top so everyone sees it first.

I am not bashing on PICO!!

ALL SCOPES have their issues.

I do wonder how it is that you use the PICO all the time and have NEVER had ANYTHING you needed fall into the gap.

Carl Grotti wrote on Jan 29th, 2011 at 6:07pm:

Really hard to show something that falls into the gap.
May-be you could figure that out…. for me and PICO both  Smiley

You have never heard me “praise” ANY scope.
Like I said they ALL have their flaws

That seems like a bit of a waste,  to each his own.

Depends

Some like to pretend it does not exist, I myself would like to pretend but it is an issue.

I would rather not continue discussing the gap issue.
It is not why I originally posted.

Paul,

I'm not bashing a Modis either.  It's still the most powerful native hand held automotive scope IMHO.

I wouldn't either, if I were taking your position.  

There are many different ways to run the Pico.  With a gap or without.  I like choices.   Smiley

Rod,

It is possible, Rod.  That was the point of Brian's post.  Try it.   Wink

I am not saying this would be the best use. What I am saying is that method eliminates the gap completely.

I meant in relation to normal operation, Tom.
I didn't know about this method and I tried it straight after reading Brian's post. I think it works great. But I think that I would prefer to have my frames to scroll back through. Smiley

I misunderstood.  Gotcha.

I agree.  However, the Snappy scopes don't have the luxury of multiple captures.  Brian's post did illustrate how one can run a Pico like a Modis on steroids without any gaps.   Cool
