HI, May someone could help,
I have a XDS3202 (14bit) scope, unfortuneately under a measurement the GND aligator clips uncained and touch a -70V rail, and after my scope semi brick,
It mean the screen, and all fuction working (the relay switch, the DMA work) except no visualable signal on the screen, (either the AWG not give any signal out) If I put direct input on the ADC IC it has visuable signal,
My investigation is may the negative -xxV power suply faild but no schematic found it.
The new main panel is almost 800€ what is not a option for repair,
If someone know the measure point and voltage it also could help a lot.
A schematic could help
