Title: DSO5102P - Baseline Problem [Print this page] Author: MaMuCh Time: 2019-6-5 00:51 Title: DSO5102P - Baseline Problem Yet another problem that's probably also a firmware bug.
How to reproduce the problem:
1. Connect both channel 1 and channel 2 to any slow signal (or maybe without could do the same, didn't test yet, I tested with 800ms/div)
2. Go to the channel 1 menu and change the coupling from DC to GND.
3. Move the cannel 1 position to 2 divs above the centerline. Works as normal, right?
4. Leave the channel 2 position there and change its coupling back to DC.
5. Go to the channel 2 menu and change the coupling from DC to GND. At this very moment the baseline of channel 2 jumps to the baseline of channel 1. You may move the channel 2 position as much as you want. The channel 2 position control has no effect anymore.
6. Now move the channel 1 position and the channell 2 baseline will follow that of channel 1, regardless what you do with the channel 2 position control.
This needs to be addressed!

OK, I investigated a bit further and I would like to add that this problem occurs with a timebase of 80ms/div and slower.
With 40ms/div and faster, it behaves normally.
(Just for amy and crew... ;-) )
Can other DSO5102P-Users confirm this?
