One of the things I wanted to know, were the references of ADCs, but no luck, they removed it >:(
Probably they are using slow rated ADCs...

probably, not that AD9288-100 costs much more than the -40, but you if a manufacturer (like Rigol or ATTEN)
save money but cutting (or actually not installing) proper shielding between PSU and main PCB then you
can assume that the ADCs are cheap once too.

right, IS61LPS51236A-200TQLI, thats about 25$ where the price diff to CML is about 150$. However, before you (or someone else) start to think about potential hack one need to be done:
- there is CPLD on bottom side of the PCB, if address counter for SRAM is done by CPLD you can't hack because ATTEN probably
programmed it different, if within FPGA then CML firmware will be the solution as it contains FPGA deisgn file.
So in principle someone having CAL need to check if the SRAM address pins are connected to CPLD.

You are right, everything is cheap, even the price of the scope, the main reason for my choice :)
What I really don't like is having the ADC's reference erased, I know that is a common practice, but I hate it.

Some more images, now about PC interface/software
About USB, the lsusb give me this:
ID f4ec:ee38 Atten Electronics / Siglent Technologies Digital Storage Oscilloscope
As expected no suport for Linux.
But you are thinking, "dude forget Linux, simple use Windows", right?
Humm... I'm not so sure.
The good part: exist a driver
The bad part: is only 32bit, no 64bit version, WTF!!!
These days I'm a Linux user, but I have a partition with windows 7, but guess what, yes, yes 64bit, so useless.
I end up going to a prehistoric desktop whit Windows XP 32bit and tested it, but, guess what, conection is slowwww.
So what? I'm quite smart, so I managed to put it working in Windows 64bit machine and also on Linux, with the more prehistoric RS232.
Here are some images of the PC software (EasyScope 3.0) running in Linux under Wine, and some captures from scope.

Yes, you must have some powers :)

When it comes to fuses on the mains inlet, indeed he does, he is British! ;)

hehe who need Linux :P
There are some Blackfin dev board having same USB chip, look for isp1362bd. There are also some Linux drivers,
i think with some trick it will work for you.
