Tom,

More on this within the week.  We are gearing up for launch.  A few details yet to be worked out but I think these will be available shortly.

The 3000 series scopes made all other automotive scopes a small dot in the rear view mirror.  This one is light years ahead of the rest.

Dual 80MHz ADCs
32,000,000 point internal sample buffer
100v inputs
20MHz bandwidth
12 bit

Not that this will diminish the value of the 3000 scopes at all.  These will never be obsolete and will continue to be fully supported.  The other brand x scopes won't catch up to these for many years to come.

But there will aways be something new from Pico.  Many of you remember when the 3000 scopes came out taking the lead over the 212 series.  The 3000 series has been the most powerful automotive scope in the world for years now.  Now maybe a week or two left holding that record.   That's all.  The only way to beat a PicoScope is with another PicoScope.    

Some questions if I may.

How many channels?

Any progress in the raster/superimposed feature?

Running 3000 and 4000 series is there a pause in the pc resources like running P5 and P6? 

Thanks Sam

I guess I was not clear.  I meant running two software applications at the same time.  Brian posted he used a 3000 and 4000 at the same time.  I have run pico 5 and 6 with two different scopes at the same time and it seems there was a delay at a consistent time basis of course I was running the signal generator at the same time.  I have this illustrated in some of my scope comparison videos.

These new scopes are arriving here today.  We have a new page under construction now where you can get more information and purchase.

Autonerdz will be doing the world debut on the new scopes at the ATE show, so be sure to stop by our booth, if you are atttending:

This is the first time these will be exhibited anywhere.

Do you have a performance chart for the 4423 ?

Is this a scope that you just set the time base to something stupid, like 500 ms or 2 sec a division, crank up the samples, and set this up as your base?

Or are there any reasons that there would be an advantage to "slowing down to go fast"?  It is very obvious that you probably cannot, within reason, go to fast, but there is usually some advantages to slowing down.

It's just that at this time I can't think of any!

Reieved the pico newsletter today so it looks like it is the official release now.

There is a couple of terms in the literature I was curious about.

What is  flexray?

What is the 'always on memory'?

Thanks Sam

Sam,

The 'always on memory' means that the scope is always utilizing the internal 32meg sample memory.  Of course, the samples are stored there in block mode operation.  But, even in streaming modes, this memory is used to process the data in real time.  This helps free up the PC CPU load.

It's amazing how well this thing works with the massive amount of data it is capable of collecting.

Comparing a 50 second four channel Pico 4423 capture with a 52.4 second Modis capture, the Pico 4423 will sample over 133 times faster.  It will collect 133x more data on just one of multiple screens.   

This means that instead of samples being 400us apart they are only 3us apart.

That's like comparing speed between a VW bug and an F16.   

Sam,

Yes, there are gaps between each full screen buffer as they are placed into the scrolling capture buffer.

The size of the gaps depend on the scope settings.  The 4000 has a rapid trigger mode where the gaps are very very small but that is only at the faster time bases. (1ms/div and faster)

The gaps, at other block mode time bases using the 4000, can be considerably less while capturing more data but...

When you get into the longer streaming modes with samples jacked up, the gaps get much longer.  This is due to the fact that the PC has to write a LOT of data to the hard drive before continuing.  In the example above, this may be around 40MB for one screen.  That takes several seconds.  However, when you have such a large seamless capture time on one screen with all the detail you would ever need, the pause between screens is less relevant.

Keeping in mind that the 4423 can collect 8x more data than a 3423 at the 5s/div example above.  So, it's not surprising that it might take 8x longer to write it to the hard drive with those settings.

So......It depends

Guess there was one of these at Vision so the above statement was not entirely correct.  I did check the Vision site and Pico site to see if there were any exhibitions before ours but none were listed.  Nothing in the Pico newsletter about that either.  I have been known to be mistaken before 

In any case, if you really want to see one as only Autonerdz can show you....ATE is the place to be. 

BTW Bryan,  I did put that 4423 performance chart together.  You can get it here:

Sorry...Picogroup members eyes only.

I'll confirm the 4423 was displayed at Vision. The vendor was unknown before my arrival.

Are there any upgrade options for the 4423 ? I just bought my 3423 kit in december. I think I read on here that there wasn't any just want to clarify.
