Rigol DHO814 Ultraacquire not ultra...

I find this feature quite nice, until just now i tried it out for the first time.

I wanted to capture some rather slow reset signals, so i tried it first with creating signals by tapping the probe on 3V by hand.

My understanding is, that it will take x captures or x seconds before it displays the curves. (Unfortunately the timeout only goes to 1s!  |O)
While trying it by hand, i found, that it will just randomly copy curves sometimes even 5 times (!).

There cant be hardware or software limitations, that it can only go to 1s can there? It does not matter how many samplepoints i set.

I somehow got the feeling, that not much time has been put into testing this product, before it hit the market...

This function is so buggy for me, that's why I gave it up.
the software freezes several times.

I'm afraid "UltraAquire" is just a marketing ploy, designed to enable Rigol to put high waveforms/second figures and a "unique feature" into the datasheet. It is not meant to be actually used. :-\

I had tried it umpteen times, in different variations and came to no conclusion, except that, as ebastler already wrote, it must be a gag.
