I'm looking for a used 4 channels scopes on eBay.
I have preferences for HP and Tektronix.
Anybody owns (or owned) this type of scope ?

Looking at the 10th picture showed:
All the 4 channels are on the screen but it looks to me that
some of them shows DC offsets (no probes connected..)
I can see the channel#1 ref dot line completely alone
but many signal lines are over it..
Channel#1 at 2.00mv/div
Channel#2 at 5.00mv/div
