Has anyone seen software to capture the analog outputs of older spectrum analyzers, oscilloscopes or anything with an X -Y output? I currently use my digital camera if I need to capture an image off of any of my CRT displays. I saw this article: Widy boards But it does not discuss anything about the 'custom software'.
I thought about using the x y outputs and feeding them into a sound card input for processing. Seems like a lot of work to just digitally capture the same image I can obtain with my camera.

If you've got a digital camera image of a scope or spectrum analyzer, and you want to remove parallax, pincushion distortion, rotation, etc., AND you want to extract the (X,Y) data into a .CSV file for further processing,
then Bob Cordell's book has a great little tip in section 20.3 (p.425): try out the free Engauge Digitizer software

The original signal I am measuring?
As much as I use my sound card and various software; many times I just use my actual instruments. I revert back to my analog scope so often vs my digital scope. Same thing when looking at basic distortion, I use my spectrum analyzer instead of sound card and software. I was just curious if a software existed that 'plot' the x y output.
Thanks.
Yes. That's the easiest way.
If you can save the data as numerical, Excel will certainly let you do XY plots. And if you can't bear to stop using the instrument, you can capture the X and Y outputs and plot them. I use Virtins Multi-Instrument for things like that.
I really like ARTA, but more and more I have been looking at the Virtins software. I think the $99 Standard version would be best for me to get started. I see the other add-on packages as well.
Thanks SY. What is your feedback on the Virtins software (you don't have publish anything negative)?
