I'm new to the group and sadly a long, long ago degreed EE. I pickup up free scope that hadn't been used in MANY years and I personally haven't touched a scope literally in 45 years!
In my excitement, I plugged it in, waited for it to warm up, saw a faint trace, grabbed a 10x probe and foolishly tried to read line voltage. My GFCI powering the outlet immediately tripped. No now trace. Any thoughts on what I've damaged? Please try to hold the laughter. I can already hear it! haha ....
