[TriEmbed] Fwd: Re: Oscilloscope Question

[The MacDougals]

I will bring my QA100 tonight.

 

https://www.quantasylum.com/content/Products/QA100.aspx

Dual Analog Channel w/10-bit ADC… 

100 Msps, Deep Buffers and 12 Digital Channels...

Unmatched features & performance for $349

 

It has 2 analog channels and 12 digital channels.  The only drawback so far is that the digital channels are 3.3v.

 

I documented a logic level converter board I made here: http://triembed.org/blog/?page_id=570

(Disclaimer: I have a professional relationship with Seeed)

Seeed Studio has an update to their DSO nano, the DSO Touch:

https://www.seeedstudio.com/blog/2015/03/23/dso-touch-in-stock-now-an-update-to-dso-nano/

It's in pre-order status, but shipping starts in a week or so.

Seeed sent me a beta DSO Touch a while back, and I took a stab at making an overview video. You can see how presenting and video production are not my forte here: https://www.youtube.com/watch?v=C7K5zrWMWVg

I made the video last year when the DSO Touch was in Beta, so some of the features of my device may not be the same. I had the video hidden until today.

The DSO Touch is $149 at Seeed (I don't carry any on my site).

I have a personal DSO Quad I bought a couple years ago, and I love it, though if you are used to a "pro" scope you may find it lacking.

I'll bring in the Touch tonight if anyone wants to check it out.

​The Red Pitaya has 125 Ms/s inputs and 50 MHz analog bandwidth

That is not the same as a 100 MHz real time scope ​which typically has 1Gs/s 

 

Interestingly Sparkfun has one for $400! Which costs less that Red Pitaya

Although there is nothing wrong with Red Pitaya as an open source signal processing device, just it cannot do 100 MHz.

 

Cheers,
