question about oscilliscope

[eternalightwithin]

Looking to buy an oscilliscope. Looking for a 100MHz one. Several on Ebay. There is this cheap one a Nicolet 204-A. What is the specs for it. Can't find specs anywhere.

Never heard of that one. But most name brands go for around $1000 so depending on price it might be worth a gamble.

Wanted to give an update on this. So it was dropped but it does power on and seem to work per se. Didn't come with probes to test on anything.

I know it was made after 1980. As you can see it has state of the art data acquisition module.

So if this works, I think I got the best deal of the millineum. As I think this scope goes down to nS range. The back has a digital I/O port. Maybe I can find one and attach to PC?

Here are pics.

What do you think?




Look at those fu...freaking big caps. Dang!

Appears that something was slid into the side, but aside from cracking the bezel it looks OK.

Did it come with an operators manual?

Yes, Like 3 of them!

Still not sure on full capture speed. At one point it says 50ns/point. But then somewhere else it's says"full analog bandwidth 7MHz min/max" Sigh, I hope it's more than that.

Anyways, what kind of probes should I get for it?

If a scope is, say 25MHz, can I just used 100MHz probes?

(Hay that's a lot better then an old HP scope I had with a 250KHz response. )

Sure, just don't expect an improvement in performance.
