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.
They're also cool in that their Y resolution is insanely high for a
digitizing scope. Most are 8 or 10 bits. Most of the Nicolets are 12
or 16. They're for very high-resolution, low-speed data analysis, and
front-ending FFT analyzers and stuff like that. I've used them in a few
different jobs, and I have (I think) two around here somewhere. One has
a blown power supply; probably just a tantalum cap (Hi Dan!) as you
mentioned. If you have a chance to scan that service manual, I'd love a
copy.
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.
Ok that's really cool.
