PC based fft

A potentially useful way the address the resolution issue might be here:

http://http://www.virtins.com/

Not a lot of useful stuff seems to be said here, Too many seem to not have not weaned themselves old fashioned analog scopes,

you tested virtins? works OK?

specs of VT DSO-2A10 looks OK!

I was looking to purchase a DS1054Z but dont know after found virtins :/

Before spending money on software, check out Visual Analyser (I think someone already mentioned this software). It's pretty good, mostly. I used it to do some THD measurements in a kind of spectrum analyzer/scope mode and I found it to be quite useful that way. I was also able to create a custom multi-tone stimulus signal so that I could measure loudspeaker IM distortion.

Example measurement:

Thanks for the tip! but this soft is compatible with some special hardware?
