experience with USB osiclloscopes?

Has anyone bought one of the PicoScope USB-based oscilloscopes? I was
looking at the model 3206. Is this a good unit? Does the company provide
everything they claim they will?

Thanks for any insight....

Are you sure that 8 bit resolution is going to OK?

Anyway, there are other models with different specs so any shortcomings
will be down to the purchaser ordering the wrong model or not
appreciating the specifications.

I couldn't find anything else out there after doing an extensive web search
with higher bit resolution and still providing a wide enough bandwidth (I
need at least 200MHz) while still being within reason for cost. 8-bits
seems to be the norm for high-speed (that's reasonable). The other
functionality of the package (bullt-in spectrum analysis and function
generator) of the 3206 makes this a pretty good value for the cost. To be
sure, there are a lot of 10 and 12-bit resolution PC scopes but their
bandwidths are usually about 50MHz or less.

Thanks.

I bought not to along ago a cheap chinese knock off that works
very nice for the price..
20 Mhz dual scope (color), with DMM, separate inputs with isolation
between all inputs.
I paid under 500 for it. I think they have also a 60 Mhz version..
this comes with carry case, real probes, divider block etc..
It's your choice..
I did see a post once about a USB scope and the user wasn't happy.
I can't say if it was the same model how ever, they did complain about
jitter and lag..

500 sounds expensive.
I made my own for Ł20 in components and a couple of hours to write the
software.

When you're looking at USB scopes be sure that you look also at the
single-shot sample rate and not only the "equivalent" rate that they
may give for repetitive events. The single-shot bandwidth for
reasonable reproduction of the signal is about one tenth of the
single-shot rate.

for 20 Mhz dual trace?

I'd like to see that.

If it's anything like your PCB design software, it'd be fair to say that it's
lacking a lot of functionality that those Ł500 units provide, yes?

There are a *lot* of "toy" USB oscilloscopes out there...

Hi

Is there any digital to analog converter that would have a minimum
sampling rate of 500 khz and that can be directly connect to a Pc computer
USB input ?

Thank

Gaetan

No.

You would need to buy a USB scope and PC software.

The alternative is getting into microcontrollers, USB and PC software.

Hi

I found a web site using a Pic but it's seem hard to program it.

Here's the link;
