Can you discuss how you handle measuring Class D amps? Trying to look at the output with a scope doesn't work. Trying differential probes didn't help. I just found some info from TI and other sources that explain the need for at least an RC filter on the output, so I was hoping you could tell us how you handle this issue. Maybe your equipment has provisions that handle the filtering? Do you have a recommendation for those of us without the big $$ resources?
