Rick, it just means that it takes about 3 minutes to load the old v2 firmware, if you decide to revert back from v3, after trying it.  And more like 4 minutes to move ahead again to v3, due to the larger size of the image.

I.e., neither difficult nor time-consuming to try both, and decide which you prefer.

I wanted to learn about the lithium battery (cr2032) in (ds2072)
it is only responsible for the RTC belt ?? or remove it if it does not affect the calibration data???
in some multimeter Rigol which battery is installed to preserve the memory of calibration constants....
important question of who can know?

It is only for the RTC,  as far as i know there is no alternative for a RTC, you need some battery.

Some photos of my DS2072A from inside.


I feel some problem here...

I think I'll resolder those clips later. :-/O

Some interesting stuff with front panel:


I can see covered hole for signal generator button (to the left on photo) and... hole for "logic analyzer" button to the right? :-DMM


And some buttons ripped off from membrane:


Encoders are some "LJV":


And waveform playback control is from ALPS:


Full album here (Russian langauge).

Here's a weird bug in the average function :

-hook up channel one to the 1khz test signal
-hit auto button
-change timebase to 50ms

now your signal just looks like a wide band, like you'd expect on a graded display. OK.

-turn on averaging in the acquire menu, 2x will do nicely.
-> wtf! what happened to our signal? the wide band just turned into a small ribbon
-it gets even weirder when turning on anti-aliasing, now the ribbon is waving over the screen

What is happening here? The scope is fetching 14Mpts, so there shouldnt be any weird aliasing things happening, but still it's there.

It looks normal again when you go to 20ms timebase.
miguelvp:
I got the same result, it's very weird!



But at 20ms timebase I see artifacts that shouldn't be there either.

Edit: adjusting the trigger affects the shape, tried also AC coupling and same deal.
