Does anyone know of the requirements for demo equipment in Japan.
Specifically, a broadband digital transmitter that a customer wants to
evaluate. Does the demo unit have to meet all regulatory requirements?

Issue
The requirement for 30 meter testing was removed in EN 55022-1995. The
current distance requirement for both Class A and Class B is testing at 10
meters.

Jim,
You are correct in that a new set of antenna factors now must be generated
for the 80 MHz tuned dipole covering the frequency range of 30 - 80 MHz.

I think there may be a little confusion here, let me see if I can clear it
up. In your e-mail you refer to calibration of a site. My original message was
related to measurement technique for radiated emissions measurements. This is a
separate issue from site attenuation measurements which
In ANSI C63.4 the required antenna is a half wave tuned dipole. There is an
allowance that lets a broadband antenna be used provided the results can be
correlated to the half wave tuned dipole. When performing radiated emissions
testing to CFR 47, Part 15, using ANSI C63.4 the requirement is to
In GR-1089-CORE Section 3, R3-3 is a requirement and the wording probably

an objective hence the SHOULD NOT wording. When this changed from a objective
to a requirement on 1/1/96 O3-3 became R3-3. When
