know anything about this pocket oscilloscope over at ITead Studio?

[slburris]

No, it's not the DSO Nano or clones, check it out:

Anyone heard about this?  Looks like it will have real ADCs
driven by an FPGA, like you would expect in a real design.
The prototype display looks interesting too.



No real specs, just a kinda wishlist of features.

I don't know about this one, but I have to warn you DO NOT get teh DSO Nano. I've one and it is completely POS. Very slow update. The menu system is the worst and many times you press the button and it is not doing anything. Very disappointed!

From that experience I'm very scare of the pocket DSO. Just my 2 cents.

Still need to ask the $500 question: is it more than that?

The fact that the sample screenshot shows a 10Hz sine and 20mS 'none' doesn't make me hopeful about sampling rate. It looks like they use one ADC, the highest speed grade is 100MS/s, and that may have been multiplexed for both analog channels. If that's true, it doesn't really qualify as anything else than sexy toy in my opinion, and the 175MHz -3dB bandwidth for the op-amp is completely meaningless.

It might be a POS but it does look quite sexy.

The site says the target price is around $125 for the board without a case if
I interpret things correctly.

Looking up the AD9288 and AD9218 chips, they are both *dual* ADCs up to 100Ms/sec.

So if they run these at full rate, the scope should be able to display stuff up to at least 20Mhz
real-time.  That's a huge step up for this nano-scope class of devices.

And they are charging barely any more than the nano?! That's sound too good to be true.

I found a thread about this scope in Chinese at:

I'm having some trouble with the translation, but if I've read it correctly,
the higher end model will use the dual ADC clocked at 72Mhz.  If using
a single channel, both ADCs can be used, for a sample rate of
144Ms/sec.

 "36M +36M" : presumably  36MHz bandwidth

I just saw a ebay auction for a preorder for one for $250!

they call it a dso nano 2

Hmm, I thought it was against ebay's rules to auction off something you didn't actually
have? 

Still, it will be interesting to see how this gadget pans out.  With 1 input, that's a 72Ms/sec
sample rate, so figure you can easily watch 10Mhzish signals with 5-10x oversampling.
That's starting to be actually useful, unlike the DSO nano which is basically a cute toy.

theres the url, says he has more than 10 available.. yeah right, not on a pre order.. dont think I'd pay 250 for one though, since I just purchased a rigol 1052, just gotta wait for it..

[safarir]

Anyone know what screen he is using ?
