hey guys
could anyone please help me out (I hope one or all of these problems weren't asked yet, it would mean my search skillz suck)
kinda annoying and I don't know why this happens all of the sudden: I power off my DS2072(2302) normally and pull the plug. Now, whenever I put it back in the next day, the DSO resets itself (like it does after self cal for example)
how can I stop it doing that? (and why does it reset all settings after self cal, it's so annoying, too)
(I don't believe the backup battery only lasts 6 months or something like that ...)
the 2nd problem is about measuring. I try to measure/calibrate an ECG circuit, setting it to 5 mV/DIV. If I don't use high res, it's really impossible to measure anything.
(I even tried avg@32 to be able to see a line on the DSO)
increasing the time base to something like 10 ... 100 ms/DIV makes the DSO totally slow, no matter what sample memory I select (the lesser the memory, the weaker the visibility of the curve on the screen)
I still remember my old HP DSO which was nothing compared to the Rigol and I was able to measure and display what I wanted to.
What do I have to do to get a nearly clear curve on screen?
I can't see an ECG curve on the Rigol because it refreshes so slowly :/
thanks so much for any help!
