Hi Daniel,

Hi Daniel,

You can probably do that with GNURadio, I mean you can use the basic
processing and display blocks in any Python/C++ (and probably others)
program. But as far as I know there is not much software in GNURadio to
interface the multitude of devices out there.
You should check out (lib)sigrok and Pulseview. This is a library and a
GUI exactly for this purpose (and others) and they support a ton of
devices. Interestingly there seems to be (20 second google search) no
direct interface between sigrok and GNURadio (except for pipes/files I
guess) - this could make a nice project which would add a lot of value
to GNURadio (I imagine a sigrok block in GNURadio, which can be
configured to capture stuff from all the supported devices or send a
data stream to them - sigrok can also control instruments like frequency
generators, ...).
However, I think you can do it, but GNURadio is not the right tool for that.

Fabian

Oscilloscopes have changed a lot in recent years

Has anybody used GNU Radio to make a basic oscilloscope?

There are many generic ADC to USB devices now, some are purpose-built
for use as an oscilloscope.  Has anybody tried any of them in a pure
free software environment, either with GNU Radio or other software?
Examples[1] on eBay.

There have also been some open hardware projects like ScopeFun[2], has
anybody tried it?  They sell[3] it for $750 and the software is all
free, open source.

This area is probably quite interesting for hams, hobbyists and students
who don't have money or space for full size lab equipment.

Please note I'm not only interested in RF-oriented analysis here, some
people may simply want to analyze their audio signals, Arduino PWM
outputs or some other things below RF.

This could also be a useful topic for one of the proposed GNU Radio
amateur radio workshops.

Regards,

Daniel
