'[EE]: osciloscopes.'

Been reading a lot lately about scopes and how great they are, I agree. I
got mine free from a guy who's
wife threatened to leave him unless he disposed of some of his junk..(My dad
always calls my wife an
electronics widow !)  It's an old Dual trace scope, all modular so you can
remove the y1, y2 and timebase
modules are replace them.. packed with valves and it takes about 5 minutes
to warm up :-) Made by a company
called "Solartron" - don't even know if they're around anymore(?) Might even
be considered an antique by now.

It's obviously not a DSO given its age :) but it has a nice feature which I
haven't found while looking for a
decent used one- Z modulation (brightness). Is this a common feature on
scopes nowadays or not?

I've been meaning to build a DSO module for it for .. well years.. but I
think it would be for fun rather than
being particularly useful.. Don't think I'm up for building something that
stores 1G samples.

Z mod is on most scopes, though it's usually on the back, and often ignored.

A DSO front end could be pretty cute, especially if you hide it in a
drawer, or inside the scope itself.

A 1945 oscillograph-wobbulator with storage, and four channel readout, I
love it! :)

Yeah, its on tha back on mine, last time I tried to tinker with it I got a
couple of hundred volts of tingle running through my fingers and breadboard
so I havent touched it since, but it's an attractive feature for me because
I like building projects that show images on my scope.. Z mod is the next
step.. so I can watch TV on it :)

I was going to remove one of the y modules, and build a new version..
without the valves :) and with some nice DS features, theres only space for
2 y modules and a timebase, but they all plug into a backplane in the scope
(which weighs about 20 pounds with no modules installed anyway) so I have
access to the timebase, Z and both y channels. I was thinking of useing the
other chanel to write some text on the screen- pic controlled of course :)

I just discovered that solartron still exist but I dont think they are
still in the business of making scopes anymore, I might just give them a
prank support call tommorow to see what happens.. :) "Oscilloscope sir? we
havent made those for 30 years..."
