(AC) power line the radio frequency voltage that is conducted back onto the AC power
line on any frequency or frequencies shall not exceed the limits in the following tables.
Compliance with the provisions of this paragraph shall be based on the measurement of
the radio frequency voltage between each power line and ground at the power terminal
using a 50 µH/50 Ohms Line Impedance Stabilization Network (LISN).

Table 7. Conducted Limits for ISM (Ultrasonic Equipment) calculated from FCC
Part 18 Section 18.307(a)
18.311 The measurement techniques which will be used by the FCC to determine
compliance with the technical requirements of this part are set out in FCC Measurement
Procedure MP–5, ‘‘Methods of Measurements of Radio Noise Emissions from ISM
equipment’’. Although the procedures in MP–5 are not mandated, manufacturers are
encouraged to follow the same techniques which will be used by the FCC.
Test Procedure:
The EUT was setup on a wooden table, 80cm above the ground plane. The method of
testing, test conditions, and test procedures of CISPR 22 were used. The EUT was
powered through a 50Ω/50μH LISN. An EMI receiver, connected to the measurement
port of the LISN, scanned the frequency range from 150 kHz to 30 MHz in order to find
the peak conducted emissions. All peak emissions within 20 dB of the limit, six highest
peaks were re-measured using a quasi-peak and average detector.

18.311 The measurement techniques which will be used by the FCC to determine
compliance with the technical requirements of this part are set out in FCC Measurement
Procedure MP–5, ‘‘Methods of Measurements of Radio Noise Emissions from ISM
equipment’’. Although the procedures in MP–5 are not mandated, manufacturers are
encouraged to follow the same techniques which will be used by the FCC.
Test Procedures:
The EUT was placed on a non-metallic table, 80 cm above the ground plane (See
Photograph 2 - 5) inside a semi-anechoic chamber. Measurements were made with a
loop antenna.
Radiated Emission measurements were made in accordance with the general procedures
of ANSI C63.4: 2014 "Methods of Measurement of Radio-Noise Emissions from LowVoltage Electrical and Electronic Equipment in the Range of 9kHz to 40 GHz" as well as
the procedures delineated in FCC Measurement Procedure MP-5, “Methods of
Measurements of Radio Noise Emissions from ISM equipment”.
For each point of measurement, the turntable was rotated and the positions of the
interface cables were varied in order to find the maximum radiated emissions.
Measurements were made at 1.2m. A roll-off correction factor was calculated and applied
to this measurement.

Test Results:
The EUT was compliant with the requirements of this section. Measured emissions were
within applicable limits.
