I'm not sure I understand your question correctly, but I will try to provide an
answer. ANSI C63.4 is used when testing for FCC part 15 subpart B compliance
for unintentional radiators. When testing a table-top system, the collocated
equipment should be spaced at 10cm, unless this is
Actually, C63,4:2014 is the FCC referenced standard now, not C63.4:2003. So,
the 2014 edition should be used. In any case, the FCC generally requires that
at least one of each type port be filled on the EUT and a minimum of at least
of the different type 2 ports be filled on a host that is

In regards to the daisy chaining:
Hook up equipment (daisy chaining) until such a time as you don't get a 2 dB
increase of any unwanted signals. I think this is in ANSI or CISPR?
Everyone,
What am I remembering partly here?

It's been awhile, but at the time when wanting to understand modular test
requirements, the 2dB asymptote/leveling off was a reference in FCC Part
15 Section 15.31 (a) (3) pointing to ANSI C63.4-2003.

To add to Rich's answer which is correct;
I am very involved in this now, and at the recent TC108 US TAG meeting in NC,
the US committee unanimously voted no as this standard has so many technical
issues, especially relating to RFT. I personally had comments in regards to
almost every line

Regan,
I think the EMC community can agree that just because a device label indicates
it is compliant doesn't mean it really is. We see that in the lab very often.
ANSI C63.4 does offer quite a bit of detail regarding EUT setup & operation,
connection of EUT ports and peripheral and accessory
Hi Bill. Thanks for this great info! Much appreciated.
The second part of my original email was merely philosophical discussion
points. Let me clarify. I would love to hear what people think:

main EUT? i.e. PCs or
Right - ANSI C63.4 still makes reference to the "2dB rule"

Hello,
I have a question regarding radio certification testing.
Given that the EUT is the RADIO it is my opinion that all
other emissions ( for example from DDR signals) that do *not*
fall in the restricted bands can be discounted.
Am I wrong??

Mike,
There are some drafts available from ETSI. Also given is the current status of
ETSI standards.

Here is the problem with the ‘2 dB rule’. If there are only two ports it
simply makes more sense to cable the ports. If the device passes, go no
further. If you only fill one port, then you have to still fill the remaining
port to meet the 2dB rule, even if it passes. So, why waste the
RE: Myself and another gentleman who helped with the ITU-T K.50 revision are

There is an important point here. If you don't take part in standards work in

Also, here is something else I thought of that might impact your original
question and reinforces Rich’s response as well. (even if you are not RFT.)
In the scope of 62368-3 there is a really ambiguous and strange sentence that
exempts some DC power transfer equipment completely from 62368-3.
Depends. Any digital circuitry used in the process of a modulating the radio,
is considered as part of the overall transmitter and would need to pass
restricted band requirement for FCC.
If the DDR signal is not used by the radio in its transmission, is not required
to be on to transmit, or

The prEN document is only a formal notice at present, not the proposed standard.
The underlying IEC standard is still at the CDV stage. You may be able to get a
