Have I got an old copy of CFR 47?
I happen to run across this paragraph the other day?. I can't be more than a
year old, as the CD ROM its contained on was purchased around that time.

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

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

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

These are all in the CEC and US NEC. You need to purchase one or both

I have a question about record retention.
We make ITE which incorporates lasers and certify to LVD, EMC directives.
We do not create a TCF specifically. We do have outside lab test reports
for safety and for EMC. We also have the usual parts lists and CAD drawings
for fabrication and assembly
I tend to agree with Gary that disk drives do not heft a big load change and
cause flicker. I have repeatable lab test proof of this on an ITE product
we make that has ten disk drives (each ranging in capacity from 9 to
50Gbytes). I have run flicker test while the box is running a program we
Here is our present status. We added ground screen across the table and
soldered it down. We now pass 3m horizontal by a fraction of a dB, but
vertical is out over a dB. When we moved the receive antenna out to 10m we
passed vertical! We are using tuned dipoles and have shown that they are

I once had (thought I had) this problem. At least one version of this

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.
