I had a chance to visit Com-Power Com-Power (http://www.com-power.com) in Brea, California, this last October, just prior to an EMC seminar I was presenting for the IEEE EMC Society – Orange County Chapter at CKC Laboratories just next door. Com-Power makes a variety of EMC measurement tools and probes and they graciously allowed me to review their broadband preamp.
