Hi
While tektronix make great scopes, I wouldn't say
they are the only choice.
I've used many over the years and have no complaint
on the tek scopes.
Still, my main home scope is a Leader 4 channel 100MHz
with delayed sweep. Other than the occational flakey
switch contact on the push buttons ( poke them a few times ),
the trigger works as good or better than any of the tektronix
I've use. Clearly better of any HP from that time frame.
I have found the occational need for a digital storage scope.
I've been using a old Nicolet Explorer III with the 204 input.
It works OK but these are really old and it pops a tantalum
cap every now and then.
They are kind of cool in that you can capture onto a disk
for latter looking at. The one I have has a 488 interface
as well. Many come wth none and some even have a RS232.
Should anyone get one, I do have a copy ( I mean copy )
of the service manual. A needed addition to keep them
working.
They are kind of cool in that the scope runs on a 2900
bit slice processor.
I've used the storage scope to look at floppy data. I use
the delayed sweep on the Leader to trigger the storage.
Klunky but it works. I can pick out sectors that way.
I have an old logic analyzer but haven figured how I might
use it.

I'd forget anything not tektronix for analog scopes.

will come to wonder how you ever got along without
one, even if it's a
2-channel analog scope with relatively low bandwidth. They're so
useful for so many things; I promise you won't regret it (as long as
you don't go bargain- hunting and find one that you also have to fix).
Indeed, I bought a Hameg HM605, it was working OK, although not fully
calibrated. But it has now developed a fault, with the probe not
connected anything, move the y-POS off the zero line and
you get a 100Hz square
wave. Might need another scope to fix this one....

What makes would you suggest, beyond Tektronix and Hameg, are there any
other makes that are generally good and won't cost the earth second hand?
HP, Gould?
