Unfortunately, I believe the HighRes mode is only used to generate the display from the sample memory - I don't think it's ever actually saved anywhere as 12-bit. Originally, because the SCPI command set has a special command to transfer samples in WORD format, I thought that it would be possible to get the 12-bit data out of the DSO. But I did some testing transferring the sample memory in both Normal and HighRes modes (as BYTE and WORD) - and it was exactly the same.
BTW, I did pass on to Rigol (via Drieg) that it would be nice to use the WORD command in order to get the 12-bit data out of the DSO.

Hi
I think one has to do the hires in PC. Perhaps one can find a better algorithm as boxcar.
In PC you have more processing power and more time.
Hires is a kind of low-pass filter. Perhaps I have soon time to introduce me in digital filter.
Best Regards

Ha, ha ;D When I just sent my DS2000 a SCPI command to make the DSO enter Logic Analyzer (LA) mode, it responded with the following message:

Sorry, I misunderstood you. Yes you can post process via a boxcar averaging to get more resolution; I've done it successfully.

Yes, i have tried also lots of AWG variables, you can write to and read back...
fun, but nothing you can use for something.... :-[
