I am researching the CE requirements for Railway Electronic detector equipment.
I don't believe the LVD is applicable. Any Ideas.
Thanks

Have I got an old copy of CFR 47?

Hello group,
I need to order some attenuaters for NSA: 3db, 6db, and 10db. I looked up a
few sources and almost had a heart attack. I'm getting quotes of $120US per.
These are for 10 watt, DC-18Ghz parts. Is there a more common part (less power
and bandwidth) that would be less expensive?

Hi,
The guidelines on the LVD state that the documentation has to be kept "for
at least ten years from the last date of manufacture of the product." Other
Directives talk about the lifetime of the unit but not less than 5 years. I
guess the answer depends on what is longer. 10 years or the lif

Hi Scott,
A while back I inquired with TUV, UL and FCC about this very subject.
UL and TUV is pretty loose about manufacturer's recordkeeping of production
run information, but product safety test data and related filing information
is expected to be retained for at least seven years after last pr

Hi,
We are looking for SAR equipment. Can anyone tell us where we can buy the
SAR equipment? Thank you.

Richard,
Has it been particularly dry where you are this year? I recall from my
military days a story about a particular antenna installation had problems
when it was particularly dry. This was a circular antenna array of about
100 feet in diameter. When the ground got really dry, they had to
In my experience it is very unusual to have large NSA
variations from the ideal in horizontal orientation.
SUGGESSTION: It would appear that you have a large
ground screen. I would suggest you perform a site cal
at 3m in another area of the ground screen that does not
contain the turntable. If

One final note about list operation problems. If you have a problem with
multiple posts, or some other weird condition related to the EMC-PSTC list

I can think of the following items that must be investigated if an OATS is
not vertically NSA compliant. Can you think of others?

* Antenna factors

These are all in the CEC and US NEC. You need to purchase one or both
(they're significantly similar on all of your points in question).

I tend to agree with Gary that disk drives do not heft a big load change and

Tania,
We have not "harmonized" US safety mark demonstrating compliance with
UL1950: UL, ETL, NRTL. I've been asked a rhetorical question "which US mark
is better". Europeans have at least a single CE mark which, in addition,
covers EMC.
