Thanks!
In other
happy news, I repaired my Tek 575 this evening. It had
physical damage to the step generator switch that was holding it in an
impossible mode (single-family AND repetitive sweep) and a bad 6AL5 tube
in the step generator, so the step capacitor never got discharged. It
works great now.
Congratulations! I have a 561A that makes me happy. :-) I do need to
clean its switches,
though. FWIW, I'd love to find a 3A74 plug-in for it. There's enough
stuff that I do with vintage machines, requiring not screaming hot
bandwidth but multiple inputs, that the 3A74 would just be far too cool
for words. Just sayin'?
The vast majority of even modern electronics design doesn't need a
really fast scope. Some parts do, but not many.
I also have a HP 1741A that I use for faster things.
At the Museum we
have Tek digital 'phosphor' scopes.
Those are pretty nice. I have a TDS3012 that I use a lot, but not as
often as my 2465A.
When people on this list say they don't own an
oscilloscope, I wonder how
they fetch water, cook their meals and eliminate their waste products.
For folks who do what we do, a scope seems that basic, to my way of
thinking. I don't use it every day, but when I need it there's no other
tool that compares. -- Ian
Yup. On those rare occasions when I have nontechnical visitors, I
cringe when I hear things like "why do you have these old RADAR scopes
in here?"
I try really hard not to associate with such people. ;)
