hi everyone

today i suddenly started getting problems with my baseline. like a cyclic pattern.
i noticed it matches exactly with the measured voltage across the lamp.
i attached a snip - baseline is green and dad voltage is blue.

is this a symptom of the end of my lamps life? or is it due to the mains supply?

please right click -> open image in a new tab

thanks in advance

kate!
How many hours on your lamp?
I have seen a similar pattern before that was remediated by changing the lamp.
