Digital Oscilloscope

Lads - this looks like something useful to own.

Given a 10x probe is about $25.00 seems pretty cheap and way good enough for analog.

Just FYI

You could always check this out......FREE!

But I would recomend just buying one......you can get some nice scopes on ebay forunder $100

Yes there is some free stuff that works off your soundcard but you're not going to get even 20kHz through it.

100MHz for ~$100 seems pretty good in comparison.

But you're right - you get what you pay for.

I'd like to pick up an oscilloscope for amp building and troubleshooting, there are about a million Tektronix scopes on Ebay for a wide range of $, what specs should I be looking for? I'm willing to spend up to $400-500 for a good scope, but would be happy to spend less.

Along the same idea, can someone recommend a good book/resource for learning what can be done with an oscilloscope?

465B that is tested and guaranteed is very hard to beat

anything that has 2 channels, 100Mhz should do fine..calibrated and warantee would be a plus...like with anything else "you get what you pay for"

I use an old HP vacum tube scope (can't remember the model off hand) and it works just fine for audio....I payed $25 for it. 20 years ago it was probably worth $10k.'

Add another $100 or 200 to your budget and get something digial. That way you can save the waveforms/measurements to your PC for comparison ect.

I would recommend a USB connected scope. I use them in the field with my laptop, works like a charm.

If the sampling frequency is 100 MHz, the bandwidth is <50 MHz. Still not bad for 100 bucks. Is the software avaiable/free? The big advantage of the digital over an old analog is the ability to store/save traces. I'd be interested how robust the front ends are compared to a regular scope. I've done some nasty things to my HP
