Test Condition
The EUT was placed on a non-conductive table. The measurement antenna was placed at a
distance of 3/10 meters from the EUT. During the tests, the antenna height and the EUT azimuth
were varied in order to identify the maximum level of emissions from the EUT. This maximization
process was repeated with the EUT positioned in each of its three orthogonal orientations.

Conclusion: Pass
Note:
A "reference path loss" is established and the ARpl is the attenuation of “reference path loss”, and
including the gain of receive antenna, the gain of the preamplifier, the cable loss.
PMea is the field strength recorded from the instrument.
The measurement results are obtained as described below:
Result=PMea+ARpl= PMea+Cable Loss+Antenna Factor

A.7. AC Power-line Conducted Emission
Method of Measurement: See ANSI C63.10-2013-clause 6.2
1   The one EUT cable configuration and arrangement and mode of operation that produced the
    emission with the highest amplitude relative to the limit is selected for the final measurement,
    while applying the appropriate modulating signal to the EUT.
2   If the EUT is relocated from an exploratory test site to a final test site, the highest emissions
    shall be remaximized at the final test location before final ac power-line conducted emission
    measurements are performed.
3   The final test on all current-carrying conductors of all of the power cords to the equipment
    that comprises the EUT (but not the cords associated with other non-EUT equipment in the
    system) is then performed for the full frequency range for which the EUT is being tested for
    compliance without further variation of the EUT arrangement, cable positions, or EUT mode
    of operation.
4   If the EUT is comprised of equipment units that have their own separate ac power connec-
    tions, e.g., floor-standing equipment with independent power cords for each shelf that are
    able to connect directly to the ac power network, each current-carrying conductor of one unit
    is measured while the other units are connected to a second (or more) LISN(s). All units shall
    be separately measured. If a power strip is provided by the manufacturer, to supply all of the
    units making up the EUT, only the conductors in the power cord of the power strip shall be
    measured.
5   If the EUT uses a detachable antenna, these measurements shall be made with a suitable
    dummy load connected to the antenna output terminals; otherwise, the tests shall be made
    with the antenna connected and, if adjustable, fully extended. When measuring the ac con-
    ducted emissions from a device that operates between 150 kHz and 30 MHz a non-
    detachable antenna may be replaced with a dummy load for the measurements within the
    fundamental emission band of the transmitter, but only for those measurements.36 Record
    the six highest EUT emissions relative to the limit of each of the current-carrying conductors
    of the power cords of the equipment that comprises the EUT over the frequency range speci-
    fied by the procuring or regulatory agency. Diagram or photograph the test setup that was
    used. See Clause 8 for full reporting requirements.
