This is a first post for me, did do a search to make sure I didn't
duplicate, but hey, it may be. My apologies if so.
Picked up a GW Instek GOS-6112 on fleebay a few days ago,
just to dip my toes back into the test gear purchasing market (last
bit of gear I picked up was a DMM 20 or so years ago - but I digress)
When I unboxed it, I was greeted with this:
Oh well, like Dave says: Don't turn it on. Take it apart!

I was quite worried about that bent BNC at first, but no worries - it was just that

And finally, the working product (please excuse the photo, I was too lazy to get out
the tripod and take a decent snap)
Overall it seems to be a decent little scope, and will do the business for the time
being until I can get a fixed shop set up again, in a year or so. I whipped up a
little signal gen using an Arduino Uno (yeah, I know) and it worked quite well.
It also showed me how messy the square waves from my Ollllld (70s era)
Digi Designer actually is (I've had this for a while, why I never bothered checking
it with my last scope, I have no idea)
Any way, there it is, any one want to see more, I have taken a few high
rez shots.
