Two questions:
1. Why do they declare 1.2 GSa/s?
2. Is the actual sample rate of the 1000X even lower?
Thanks!

1. 1.2 GSa/s is 4-times interpolated, see datasheet
2. 150MSa/s

Excellent description of interpolative DDS techniques shown above in the App Note. Believe this technique is employed in both the SDG2000 and SDG6000, which both produce excellent quality waveforms.
Best,

Yeah, even me have understand it... ;D

I got the AD2 yesterday. I'm fooling around with it, so far i like it :)
I think I just need a flat cable to connect the BNC adapter to the AD2, otherwise the connector won't last long (hoping that the cable won't add too much crosstalk..).
One thing I don't like is indeed the fragility of the stuff :wtf:. I don't know how they could use them in university labs and not having them broken the first day by the students.
I should get the get the little Siglent today, will keep you posted.
