Hi Tom,
I appreciate your argument, it's something I've discussed with colleagues in
the past.
I have tested a few products where the digital bus to the radio module has
caused EMC problems. These emissions have only been visible when data is
being actively transferred across the CPU - digital
mpedance spec down to 150 kHz, and its
EUT port impedance is j4.7 ohms at 150 kHz.

we should put the casters, which have plastic wheel but metal hub
and metal supporting structure so probably not bulk non-conducting,
on 0.1 m insulating support in this case.

it would far
easier to put such EUTs on 0.1m insulating support as far as possible
also for 61000-4-4 testing.

IEC 61000-4-18 generator and the test method described in IEC 61000-4-10.
At least for slow damped oscillatory magnetic field, some manufactures
offer their IEC 61000-4-18 test generator as the current source, I think.

enough for ANSI C63.4,

Tom,
Did you get to the presentation about getting the most out of a biconical
antenna? Some thoughts contained there on antenna calibration, too.
I found some time ago that using antennas does lead to the kind of mutual
coupling Martin talked about, and also

Mr. Thomas Burke, Underwriters Laboratories Inc., will review recent
developments associated with the Bi-National Standard for Information
Technology Equipment, CSA C22.2 No. 950-95/UL 1950
which are the backbone of
the group.
Tom Bao, of the Regulatory Compliance Information Centre (RCIC) is an avid
supporter of this group and publishes on the 'Net a full listing of the
traffic that appears on this group. I may be wrong, but I think there is
a connection to Compliance Engineering
to restrict the lower limit of the height scan is not
required. As with the 1/2 wave tuned dipole I have found the best correlation
occurs when the electrical centers of the antennas are near the same elevation.

inductance, instead of stictly air core inductance - LISN specs will
give you saturation current, probably well above the current your product
will draw.
