HI, I'm testing a product that's switching at 50 kHz, modulated by a 1 kHz signal.
I'm getting a great deal of noise between 9 kHz to 13 kHz, I think is related. Specifically, it goes when I stop the modulation... Any ideas on ways to clean this up. Filtering seems to be effective, but HUGE! Thanks, Derek N. Walton Owner, L. F. Research EMC Design and Test Facility 12790 Route 76, Poplar Grove, IL 61065 www.lfresearch.com
