Hi!
I have tested in total 3 Rigol DS1052 scopes:
1.) Orderd a DS1052D (with LA, Firmware V4.0)
=> The display showed a strange flicker. White lines/stripes appeared sometimes over the screen. This happens more often when the timebase was modified.
I decided to return that one and got 2 * DS1052E as replacement Both have Firmware version V00.04.00.00.01
The first one is working perfectly. No strange flicker issues on the screen.
The second one has exactly the same white lines appearing sometimes on the screen as the DS1052E which I returned.
Both scopes are brand-new and not modified at all.
Does anybody have an idea what the root cause is?
Machanical vibration/careful knocks do not influence it at all.
Is this firmware related?
Should I downgrade it? Is this possible at all?
Here a video of this issue:
