Apparently, drieg has being using
the bugs/problems list (compiled from the fine bug reporting done by the users in this thread
) to communicate to Rigol about the problems we've found.
It appears they've confirmed most of the bugs/problems now (or stated they aren't bugs) - although they're still trying to verify one or two of them, but what I found interesting - and I thought others might as well - is the response to #12 (Rigol response in italics):
12) A bug confined to the menu selection of Channel 1 = ON and Trigger = External keeps the sample rate stuck at 1G SA/s (instead of raising to 2G Sa/s ? as it should be). The bug does not affect the sample rate when selecting CH1/EXT trigger using SCPI commands. Also, if the DSO is booted up with CH1/EXT trigger selected, the correct sample rate of 2G Sa/s is enabled.
I asked R&D about this situation, it is not a bug because DS4 and DS6 use analog trigger so if we turn off CH1,CH3 ,other channels can go to the Max. sample rate, but DS2000 use digital trigger, the advance of digital trigger is the signal displayed on screen stably and no offset compared with analog trigger .In digital trigger ,even we turn off CH1 ,but actually it still work in the background ,so the MaX. sample rate for CH2 and Ext IS 1G Sa/s .Interesting, yes? Although it doesn't explain why then the sample rate reported at the top of the screen is still incorrect sometimes.
