Subject: Immunity of commercial equipment to radar at frequencies over
5 GHz
Naftali, Are the PC's causing the issue or is it RF noise coming in
on the AC line? Try unplugging the Laptops from the AC and running
them on batteries to see if the noise goes away. You may need to
filter the AC lines going to the support equipment. If you are
testing on a make shift site yo
My experience in almost thirty years of mil and aerospace EMC work is that few
equipments fail above 1 GHz at 200 V/m. But that isn’t the whole story.
Mil/aerospace equipment is extremely well shielded compared to commercial
equipment, both in terms of equipment enclosures and cable shields. Also,
Dear Group
I am seeking information on the immunity of commercial equipment to radar at
frequencies over 5 GHz. The field strength will be in excess of 300 V/m.
There is little information available on the immunity of commercial equipment
to radar pulses at these high frequencies and levels
One more thing from ERC Recommendation 70-03, 30 May 2008 found here:

Annex 1 Non-specific Short Range Devices
Regulatory parameters related to Annex 1
Frequency Band = 6765-6795 kHz
Power Magnetic Field = 42 dB?A/m at 10m
Duty cycle =
With respect to the European Union you might try the following:
Non-specific SRDs (6765.0 - 6795.0 kHz)
EN 300 330-2 V1.3.1
Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range
Devices (SRD); radio equipment in the frequency range 9 kHz to 25 MHz and
inductive loop system
Hi Robert,

I think this will depend on your application.
The following link is the search on EFIS that might help determine this:
