Hi Neven, I'm unaware of commercial site sources that can get down to kHz, however, I should think that would be easy to build yourself. Just use poor EMC techniques (fast edge speeds, etc.)!
I've also reviewed a couple of commercial harmonic comb generators by AET - one of which was just a couple days ago. Both are posted to my Web site. I also developed a home brew comb generator that covers up to 2 GHz, the details of which I divulge during my seminars. :-) When I worked for Hewlett-Packard and later Agilent Technologies, we commonly checked site-site correlation annually. The site source was a custom affair using a high-precision optically-controlled signal generator - all battery-operated. The thing weighed a ton, but it was educational to see the results.

Does anyone have any recommendations regarding e.g. the following considerations: comb generator vs. noise generator, off-the-shelf vs. DIY, cost, etc. Thanks, Neven - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
