--- Quote ---Instrument   Introduction
DS2000 Series is a new generation oscilloscope. It has 2 channels. It has a sibling version with logic analyser DS2000D. The maximum bandwidth is 200M, and the peak sampling rate is up to 1G.

Yes, this was mentioned a long time ago in one of the first threads on the DSO. It seems this was written before the DSO was fully-developed - and obviously their plans changed and they went with the DS2000-S sibling first.  ;)

You can have that problem with anything you buy - Western or Chinese made. But I personally prefer a Chinese company which appears to practice full disclosure and straightforwardness in their published specifications - even though it's perhaps a bit harder to get a hold of the latest firmware - then pretty much every other Chinese manufacturer (including GW-Instek).

I was just curious if trial options counter that is about to expire still can be restarted on 01.00.00.03...

BTW I am joining DS2072 crowd as I decided to return couple days old DS2102 in favour of device from our Rigols' doctor "drieg" even it is cross-country, firstly because of invaluable help of "drieg" (we know it), secondly because DS2k hardware is the same hardware 1/4 price cheaper (now I know it ) and thirdly because of arrogance and ignorance of national reseller (now I experience it).

Yes - or you can use the code posted in the other thread to turn the options on each boot.

If you think they do, post an image which demonstrates this. Their Anti-Aliasing does NOT work - and is either a bug, unimplemented feature, or mistake.

sorry I may be late to the party..

The anti-aliasing function may not do what you expect but it does work. Here is an example same signal with and without anti-aliasing.  I should have tried to zoom in to see what the actual waveforms look like. But there is some difference
CH1 is ~700Hz and CH2 is @ 7 MHz envelopes.   The second picture - Antialiasing ON
