I would like reccomendations for inexpensive-ish oscilloscopes :)
What sort of bandwidth does one need, are there any materials out
there for
someone who has never used one before beyond hooking up 8" drive
test points
from a Tandon manual and adjusting the head alignment.
I have a Tek 2465 I got a few years back off eBay. It's a 300MHz 4
channel scope, and it's been a great help for debugging. 300MHz is
a bit high, but I think I only paid $300 or so for it, which I
thought was a great deal.
Pardon me for showing up late to this particular party.
I second this recommendation. I have a 2465A and it has served me
well for many years.
Also, the 465/475 family are quite nice, and are much cheaper,
pure-analog scopes. I used a 475A for quite a while and I liked it a
lot.
Other nice ones to watch for are 453s. They're rock-solid and
dependable, and have all the features you'll need. They can be had
very cheaply, and I have docs (op/svc and cal) in PDF format.
