Per-Channel or Total Capacity

Hi Adam -- in this column you say "The performance of the devices has also been expanded at the top end.  The previous Logic and Logic16 devices had a max digital sampling rate of 24MS/s and 100MS/s respectively.  The newest devices max out at 500MS/s.  On the analog side of the equation, the max sampling rate that can be had is 50MS/s.  This equates out to about 5MHz of bandwidth at the -3dB point."

Are these numbers per channel, or the total capacity of the device for all channels?

Hi Clive -- these numbers are per-channel.

The performance numbers do go down once the data rate exceeds the USB pipe bandwidth -- i.e. when you add more channels than can be supported simultaneously.

We put together an interactive configuration tool so you see what to expect for a given application:  https://www.saleae.com/#interactive-tile

@joegarrison: Hi Clive -- these numbers are per-channel.

Wonderful -- thansk for getting back to me so quickly -- this really does look like a very useful addition to one's test setup.

Joe,

Thanks for chiming in, and welcome to EETimes.  I am surprised that you are back on your feet.  It sounds like you guys had a late night last night.

Hi Adam, thanks for the welcome!  Well, the site went down around 7am our time so Mark and I haven't had much sleep.  But it's a huge day for us, one we've been working on for a really long time.  Good times to be sure.

Adam,

Interesting device. Which devices will you compare against this one?

I personally have the Openbench Logic Sniffer from Dangerous Prototypes.  I was also going to do a comparison based upon what I can find on the web at these price points.  These would be more of a paper comparison.

Can you program each channel invidually for analog or digital inputs?

According to what has been told to me and what their device simulator has on their webpage, you can have each channel taking both analog and digital or set to either or.  Each channel can be configured individually.

Based upon the basic comparison, it looks like the Saleae family of devices is offering a better device.  It has the same or better features along with compatability across more devices for the same or better price.

I was really exited about this product until I realised that it doesn't exist yet. They are still "crowdsourcing".

I would say that vaporware would be an unfair assesment.  Vaporware usually does not get to the point of funding.  This is not like kickstarter where you are trying to fund someones development budget, this is funding the production run.  I do not want to give away too much of what was shared with me, but I can say that I should have a production device in my hands in relatively short order.  Mark or Joe might be able to add more to this.

Well, I do have one of their logic analysers (Logic16) for over one year now, and it greatly saved the day several times. The device and the software are every bit as good and sexy as they say, and I will order one of the analog ones as soon as I am finish writing this, I was wondering when they will launch one with analog capabilities, and here we are...

It is easy to point the finger to a small company that tries to produce something useful, I believe their offer is honest and based on a proven past.

I must admit that the new one with mixed-signal capabilities does look very tasty...

Florinstro,

 

I think that you have put it more sucinctly than I could.  I agree that there is little to worry about.  I know that they have their production samples, and that the fundraising effort is to establish production for these devices, not particularly to fund development.  They have been developing these parts for the last 18 months.
