This is a 1960 1970s osiloscope I have plugged the machine in and the red lights come on along with the green monitor as you can see in the pic the body is in good condition for its year I don't have the knowledge to test any further buys should be awere that it is 50 60 year old and should have the ability to repair it if necessary it was used regularly by a relative and have no reason to believe it won't do the job it's for sold as seen no returns accepted any further questions I'll do best to answer them.
