maukka,
I just put up a post about using a 192KHz sound card and O-Scope software to look at PWM.
The software I used is available here:
There is a stand alone version so it can be used without installing it.
It has various filters and counters as options.
Could you take a look at it and see if something could be pulled out of it to relate to your SNOB index?
Love the name BTY.
It would be really cool if basically free hardware and software could be use to evaluate a lights PWM SNOB index.
I’m amazed at the number of lights out there that are basically awful as far as PWM on their lower settings.
All the Best,
Jeff
