Oscilloscope - Kit - 2007-01-25 11:23:00

Hi all,
I have finally decided to break down and buy a oscilloscope. But I
found I don't know what to get. As this will be by first oscilloscope I
don't need any thing fancy. I don't have a lot of money so a used one
would be fine, if it had a manual or I could get one. I would be
willing to spend maybe 60.00 usd for the oscilloscope. I did find
http://www.omega.com/pptst/HHSM310.html but I don't know what I should
be looking for.
So if you have any ideas that would be great.
Thanks
-Kit

That is 60$? Do you know thats just for the case.  The scope itself is 
probably over 1k$(if they still made them).

You'll be lucky if you find a decent scope for under $100 that actually 
works.  If your serious about the scope and can afford it then your best bet 
is to spend more money. You can get a pc based scope that is much cheaper 
than the overpriced full scopes.

I don't know about that. I've found the older 5 meg scopes for like $5. I've 
found 20 Megs for $40. I've bought and still have - in great condition - 
two - 60 Meg or higer - dual trace scopes for $100 (together). If you look 
around, you can find something to fit your needs. If there are any hamfests 
in the area, check them out.

I've seen the Velleman on eBay (new?) for $100 but I got a crt model, dual 
trace, 100 MHz with delayed sweep for much less than that there.

It sounds like you don't need anything more that a dual trace 20 MHz. scope 
(of course a 100 MHz is better). I prefer analog as apposed to digital 
(better for low level noise observations and random signals). As John Fields 
said, Ebay is probably the best place to find one. As someone else 
suggested, a hamfest is also a good place too. I found a dual trace, 100 MHz 
with all the probes and books (and of course worked too), at a garage sale 
(not a likely place to find one though).

** There is no price for the  ( " No Longer Available " ) scope in that ad.

 Just prices for probes, a carry case and a special printer.

 The scope would have cost at least $2000.



Here is a new scope for the sort of  price you like -  with a probe.

WTF? It's a "single channel" model, yet has a second input to display
in x-y mode?  How hard/costly would it be to make the already existing
y-channel into a 2nd time-based input?

Have to admit, for 100 Aus$ (80 $US) that's better than I'd expect.
But if it were me, I'd go ahead and pay $400 for their dual-trace 20
MHz model:

** Significantly more.

Plus you have no clue of the very many scope users who have no need of dual 
trace capability.

Low cost, small, sharp images and genuinely portable are real needs.

I apologies if I sound ignorant, because I am. I did not relies that
was just the case.
But I don't know what to be looking for. I was looking on ebay and
found this
http://cgi.ebay.com/ebaymotors/HP-54600A-Oscilloscope_W0QQitemZ140077351937QQihZ004QQcategoryZ43989QQssPageNameZWDVWQQrd
Z1QQcmdZViewItem
but as I don't know what to look for in an oscilloscope I don't know if
it a good one.
Thanks for the help
