There is a good way to separate UUT emissions from ambient emissions.
Use 2 antennae. Place the 2nd antenna at least 3x farther away from
the EUT than the 1st antenna. Then use an a/b N-connector switch and
you can then switch between a/b and determine if emissions are from
ambient (no change in amplitude) or from UUT.
P.S. Does anyone know the person's name that the "N" in N-connector
stands for? (also the "N" in BNC or Bayonett "N" Connector or TNC,
Threaded "N" Connector)

Hello all,
I guess the biggest problem with in-plant radiated measurements
is environmental noise. Apart from turning the UUT (unit under test)
on and off, does anyone have a good technique to separate the UUT emissions from
the environment?
In my experience (assuming you do not gave a shielded room)this could save up to
50 percent of the testing time.
(A shielded room has its own problems of course re emissions amplitude
relative to an open site)
thanks

I'm looking for low end new/used equipment to set up a small test
lab
for radiated emissions. Any names of suppliers of such equipment
in
North America would be greatly appreciated. Specifically, I am
looking to purchase a spectrum analyzer and antenna that would be
acceptable for pre scans before going to a registered lab.
Any suggestions for equipment is greatly appreciated.
Thanks in advance
