Hi Binayak
Your product is used and sold for use in the non-residential/industrial
environment only, so your product is class A and requires verification only,
even though it could be connected to a class B computer as a peripheral

Hi Lauren
Is this over the air 1700 kHz transmission or conducted over wire or AC mains?

Standard practice for EMC test labs is to test what is presented us and if a
component needs to be added or changed to make the product EMC compliant we
note the make, model and location of what was changed or added. The safety
implications of the EMC change is usually not addressed. We
Hi John
Section 15.209 has general requirements for radiated emissions for intentional
radiators (transmitters). At these frequencies you would be allowed 200 uV/m
at 3m, not much but you aren't allowed higher power until you get to 902-928
MHz band.

Hi Lauren
ELF and VLF emissions are a concern for SEM installations since the B field can
possible distort the electron beam

Hi Ravinder
Try F.W. Bell, recently bought by Meggitt PLC. I saw a probe there that goes
DC - 450 kHz, but you should contact them with your specific requirements since
they have many combinations of frequency range and sensitivity.

Good luck.

The US had limits on other unintentional radiators since at least the 50s: low
power AM transmitters, TV and radio receiver oscillators, garage door openers
For a long time (I think since the 30s) there was a generic limit of 15 uV/m
at a distance of lamda/2pi, most of the low power AM TXs I b
When I worked at FCC I remember being told the interference limits were such
that a "TASO Grade 3" quality picture would be maintained as a minimum. Not
sure if TASO is the right acronym but it's correct phonetically...

Amen to that. In 1981 FCC lab set up a demo room. We had TVs and radios
tuned into local stations. The emissions from one of those (not yet regulated)
luggable inventory recorders used in convenience stores and the like would
completely wipe out both picture and sound at Ch 5.

I used to work at FCC Lab and they have ways of getting your attention. One
story as I remember it:
Back in the mid 80's there was an IBM clone computer company named (I believe)
Columbia Data Products, at the time located in Columbia MD, They were heavily

Hi Scott,
Not sure if this answers your question, but you MUST use a Notified Body if
you test to a standard that has not been harmonized as evidenced by being
published in the Official Journal of the EU.
If you do test to a standard that is indeed harmonized and published in the
OJ, then y

Check with UL CCS in Fremont, they have two antenna pattern test chambers.
