We can test to 18 GHz in the GTEM and
on the Open Area Test Site

The Lab has changed quite a bit since this 2004 picture!
We now have a 3M Fully Anechoic Room!
Here you can see some of the test equipment
we have. You can see an HP8566B Spectrum Analyzer with QP adapter
and a HP83752B Synthesized Sweeper (20 GHz). We use the sweeper
to cal our cables and pre-amps up to 18 GHz. We also use the sweeper
as a signal source to do Immunity to 18 GHz. We have RF Amps that
cover up to 18 GHz. In the background you can see our ESD and Conducted
emissions table. We have a Receiver for true Average measurements
and two LISN's. To the right of the Conducted table you can see
one of the two BIG doors for easy access to move equipment in and
out. Your truck can pull up next to that door for loading and unloading.
Above the GTEM is a heating and air conditioning unit for the entire
4,100 square foot lab.

GTEM side of the Lab
Here again you can see our 5317 GTEM, re-work
area (complete with ESD mat microscope, re-work tools, etc.), and
customer lounge area. The customer lounge area has a phone and T1
internet connection for customer use. You can check your e-mail,
down load schematics, check the web and send out project updates.
We had a shower installed in the bathroom just in case guys want
to exercise during lunch and take a quick shower before we get back
to work. In the re-work area I have most of the common emi fix material
and lots of surface mount components like resistors, caps and emi
surface mount parts. We also have lots of hand tools for constructing
experiments. Quick note on the GTEM, if a unit can fit on a standard
oats tabletop we can test it. If it's bigger than that we would
need to test the unit in the OATS area.

Open
Area Test Site (OATS) side of the lab with a 30 x 50 ground plane
We reserved about half of the total 4100
sq. ft. of the lab for the OATS. The ceiling is about 5 meters high
and the 30 x 50 ft ground plane is covered by rubber floor mat material.
We've done a 3 meter site cal and both vertical and horizontal look
good after 200 MHz. We're planning improvements to bring the site
into compliance below 200 MHz as well. We have good correlation
up to 10 GHz between the OATS and the GTEM. We would also expect
it to correlate up to 18 GHz since the VSWR data on the GTEM looks
good. For large units that won't fit on a turntable we can move
the antenna around the unit under test. For available power we have
three phase 208V.
