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?

For the price, I love my Rigol.
I bought a Rigol DS1052e 50MHz scope a little over a year ago, when it
became clear that they could be easily hacked into a 100MHz scope with a
firmware tweak. Since then, Rigol have caught on that this was going on,
and rather than drop the hammer the firmware hackers, they just lowered
the price of the 100MHz version. You can get them for about $400 now,
new. If I were in the market today, I'd just buy the DS1102e and skip
the DS1052e hacking.
It's not the best scope in the world, but I DO think it's the best
non-used digital scope you can buy for $400.
That said, I also have an old 60MHz analog Tek scope. I think they work
well together, and I think it's useful to have both a digital storage
scope a nice cheap analog scope in your toolkit.

They're quite good. In fact, HP/Agilent rebadges and sells them as
their low-end line.

Most definitely.

I also have a DS1152e and hacked it to 100 MHz. The scope doesn't
actually sample faster, it just gives you one more notch on the timebase.
The scope is still sampling at 1 GHz. .I took it to work and attached it
to a high performance signal generator in the lab. It looked quite nice
even at 10 nS / div.
The Atten ADS1102CAL is a competitor, similar specs 1 Gs/sec 100 Mhz and
has a much larger screen. One shortcoming is the 40K sample, where the
Rigol has a 1 M buffer
An interesting feature of the Rigol is the ability to compare a stored
waveform to a sampled signal and trigger when signals don't agree.

So, I'm tracking Rigol, but does anyone
have a PC-based scope they can
compare? I like the free-standing approach, but I always have my PC, so
I would like to compare/contrast a PC-based scope with the DSOs.
I see Rigol has a USB interface. Has anyone used it? If so, what does
it offer?

Alas good and cheap rarely go together...
In your position I'd avoid valved 'scopes. Not that _I_ have anyhting
against them, and and I happy to chat about Tekky 500 series units all
day. But such an instruemtn will probably need work. Great if that' what
you enjoy (and once fixed, it'll probably be good), but not if you want
something to plug in and sue.
I'd look at Tektronix, HP/Agilent (people moan about them, but only in
comparison to Tek :-)), Gould, LeCroy (not that you'll afford one!),
maybe soem of the batter Telequip (cheap Tektronix, basically), Philips,
Hameg (but watch the triggering!),. maybe Solartron/Schlumberger.

I'd forget anything not tektronix for analog scopes.

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.

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.
