Hello,

for DS1000 I found a nice software project to do FFT with PC:

http://hackaday.com/2015/09/22/a-better-spectrum-analyzer-for-your-rigol-scope/

Is there any comparable project for DS2000 series (esp. DS2072A) ?

Or could the project above be modified for DS2000 wihtout much effort ?

( I do not still own the scope, still collect reasons to buy one, and PC FFT would be a great one :-)

If FFT is important for you wouldn't it make more sense to just buy a scope which offers FFT that doesn't suck?

Just saying...

not comparable but... you may try... http://www.soasystem.com/download/visadso/ ... test on DS2000 had been done on limited scale because the developer doesnt own DS2000 so he had to ask DS2000 owner for compatibility back and forth... you may join the development team by helping them report compatibility issue for DS2000, by contacting the provided email.

Or could the project above be modified for DS2000 wihtout much effort ?
iirc, its open source. so anytime you can inject compatible code for communication with the DS2000...
if something can select, how cant it be intelligent? if something is intelligent, how cant it exist?

There is an application you can download from Rigol called UltraScope.

It will do very fine detailed FFT on the entire memory contents if you choose that mode, but it needs to download that memory first so isn't realtime.

PyDSA can be changed to work with DS2000A. I managed to do it in a couple of hours one evening of playing around a while back. Essentially you need to change the calls that grab the data from the scope to do things the way the DS2000A expects them, as opposed to the way the DS1000Z expects them. I used both scopes programming guides to figure out how to do it. I'm pretty sure I don't have the code anymore, but it's not difficult if you are really interested in doing it.

Edit: Now that I think about it, at the time I played around with it, I think PyDSA only worked on the DS1000E series scopes, so I would have used the DS1000E and DS2000A programming guides to work it out. However I believe since then someone added support for the DS1000Z, so it may work closer to how the DS2000A needs now, but since I've never played with a DS1000Z I couldn't say for sure.

Thanks for all Info and hints.

Yes my firts idea was also to modify PyDSA for DS2000.

Just ordered my DS2072A, I'll try what is possible with external FFT.

I saw Rigol als offers nice 'real' Spectrum Analyzers ...
