Hi Bill, You're probably correct in that, while relatively high, the various harmonics are still low enough that for radiated immunity purposes, the fundamental output will still be dominant enough for an accurate test.
I did check to see whether the generator would sweep (or step) downward, and it doesn't. :-) Cheers, Ken _______________________ Kenneth Wyatt Wyatt Technical Services LLC 56 Aspen Dr. Woodland Park, CO Phone: (719) 310-5418 / Toll Free: (877) 443-9275 Email Me! | Web Site | Blog The EMC Blog (T&M World) Subscribe to Newsletter Connect with me on LinkedIn On Nov 3, 2013, at 7:14 PM, Bill Owsley <[email protected]> wrote: > Only if it frequency sweeps down instead of or as well as the common up sweep. > Intuitivily, one notices that this sweeps the fundamental freq as the leading > signal and that the harmonics just follow along in the already swept regions. > Any discovered problem will be due to the fudamental and not some unsuspected > higher harmonic sneaking along ahead of an up sweeping generator. > > > > > On Sunday, November 3, 2013 1:01 AM, Douglas Smith <[email protected]> wrote: > Hi Ken and the group, > > Sounds like a very nice generator.
