Hi All,
My $.02 worth...
I strongly disagree with what has been said regarding operation of
output fuses. You may have a case for input fuses/circuit breakers.
It is my belief that the purpose of this test, which is a cross
referenced follow through to the design requirements now contained in
Bob,
Clause 6.2 of EN 300386 states The artificial network to be used is the one
described in CISPR 16-1
[1], clause 5:
- 0,15 MHz to 30 MHz: (50 ohms // 50 µH).
Also if you wish, you can download this standard for free from ETSI's website.
IHTH.
Best regards,
Ron Pickard
S11 is the ratio of the reflected voltage to the forward voltage on a
transmission line. It is a phasor quantity, so it has magnitude and phase.
The in case of a ferrite clamp, one would put the clamp over the center
conductor of a transmission line, and then short the transmission line just
No.

You are right. The parameters for S11 and ferrite are

Hi All
Re-implementation dates,below is the best information available.
But it comes with a warning notice there are many variables to be sorted and
it does not appear to be very high on the EU priority list. So do not be
surprised if these dates slip or change. When the cost implications are

An alternative to this is have your company order all the Products from
their various sources
I'd like to add that the product need not operate correctly after a fault
condition causes a fuse to open, it must only remain safe - within the

Agreeing with both, I wish to add that while the probes are very useful in
locating the source and are not (very) useful in predicting the absolute level
of far-field emission they may be also useful to predict relative far-field
difference in emission, because with all other things equal the

Brian,
Is there any way to replace the offending Product D with another vendor? If
so, do it.
If not, can you configure the system without Product D? If so, do it.
If not, buy one Product D for your use in configuring complete systems.
Then have your customer buy your system less Product D
