I would contact ETS-Lindgren in Texas. I believe they still sell that product,
or at least should be able to provide you with documentation.
You might also attempt to locate Bill Royce (if he’s still alive),

Hi All, I just posted a review of the Applied Electromagnetic Technology's
Universal Spherical Dipole Source (USDS) harmonic comb generator. This very
unique source that may be adjusted for both horizontal and vertical
polarization and produces harmonics out to 16 GHz.

Hi All,
I just posted details on a neat DIY 6 GHz comb generator circuit that can be
ordered as a kit of parts and built for under $30. Most comb generators run out
of steam about 1 GHz, so this one might be useful to characterize or compare
chambers up to the FCC limit.
Here's the link
Thanks Derek!!

Hello all!
I am looking for a comb generator for calibrating a chamber.
The upper frequency required is 18GHz.
I know of one from ComPower and one from York EMC.
Are there any others?

Hi Everyone,
It's time for me to post a new Technical Tidbit. This month's is:
The Square Shielded Loop - Part 6, Measurements in the Time Domain Using a
Comb Generator
(An unusual use for a comb generator)
Abstract: Possible sensitivity to electric fields/capacitive pickup has been
a factor
Are you using it on an OATS or in a chamber?

Dear Members,
If you know or use comb generators, could you please have your comments on?
You may wish to reply offline.
I am asked to look into this type of instrument. It seems there are many
models and vendors around. The frequncy range for my receiver is 9kHz-40GHz.
I concern the
Group,
Are you using or can you recommend a reliable Comb generator in this
frequency range???
BTW: I will shortly need one that can go up to 50 GHz, but the 1-20 Gig is
my immediate need.
Thanks in advance,

I need a comb generator (I think) to do some in-situ component
measurements on our OATS. We have coax cables and preamps in troughs that
would be difficult to remove and I'd like a spectral attenuation plot of
them over 0.05 - 1.2
Greetings All
I was wondering if any one might have a stable comb generator (i.e.
Com-Power CG-505, EMCO Royce Site Source ) sitting around that they are not
using anymore and that they would want to sell. We have a CKC Site Pipe,
unfortunately the Site Pipe does not have a stable output
