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.

Adam,

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

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

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.

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.

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.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
