REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
Carrington:
I think it is due to the overlap of many waveforms slightly different each time, and the wave intensity processing. Like the persistence effect.
Note: Test now with average acquisition mode and only 2 averages.

Thanks! If you compare this 1ns/div image with the 100MHz BW limited 1ns/div image in your previous post, the BW limit seems to have had an effect.
poida_pie:
BUG in latest f/w, 02.01
Delayed sweep malfunctions.
To reproduce:
Ch2 must be enabled, Ch1 optional
acquire: 7M samples, normal
trigger: ch1 or not important, Auto or Normal seems to have no effect
main timebase 500us/div, delayed t.b. 100 us/div or something
Then when you move the delayed t.b. towards 1 ns/div all seems well until you select 1 ns/div..
It locks up for about 10 seconds, no waveform update, no response to keys.
Then it comes good and lets you go back to 2ns/div
Of course this DS2072 is using the latest enable everything serial codes.

I see what you're talking about, but as mentioned earlier in the thread in regards to problems with the 1ns time base:
It's another error (and there's a few of them) in an, as yet, officially unimplemented - and perhaps unfinished? - portion of firmware. As far as I know, Rigol has not started selling BW updates - but if/when someone on the forum has a DS2302A (or DS2302A-S), we can find out if the error(s) exist in the 'official' working version - and if so, report it to Rigol.
I suggest disabling 300MHz on non-A HW v.1 models. Not only is it buggy (I've had a couple of crashes from it), but it's not really perfectly implemented in the input stage.
EV:
How is it possible to uninstall only BW option?
