2 PROVISIONS APPLICABLE
2.1 Definition
Unintentional radiator:
A device that intentionally generates and radio frequency energy for use within the device, or
that sends radio frequency signals by conduction to associated equipment via connecting
wiring, but which is not intended to emit RF energy by radiation or induction.
Class A Digital Device:
A digital device which is marketed for use in commercial or business environment; exclusive
of a device which is market for use by the general public, or which is intended to be used in
the home.
Class B Digital Device :
A digital device which is marketed for use in a residential environment notwithstanding use
in a commercial, business of industrial environment. Example of such devices that are
marketed for the general public.
Note : A manufacturer may also qualify a device intended to be marketed in a commercial,
business, or industrial environment as a Class B digital device, and in fact is
encouraged to do so, provided the device complies with the technical specifications
for a Class B Digital Device. In the event that a particular type of device has been
found to repeatedly cause harmful interference to radio communications, the
Commission may classify such a digital device as a Class B Digital Device,
Regardless of its intended use.
Intentional radiator:
A device that intentionally generates and emits radio frequency energy by radiation or
induction.

2.2 Requirement for Compliance
(1) Conducted Emission Requirement
For an intentional radiator that is designed to be connected to the public utility (AC)
power line, the radio frequency voltage that is conducted back onto the AC power line on
any frequency or frequencies within the band 150kHz to 30MHz shall not exceed the
limits in the following table, as measured using a 50MH/50 ohms line impedance
stabilization network (LISN). 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. The lower limit applies at the band edges.
Frequency
MHz
Quasi Peak
dBμV
Average
dBμV
0.15 - 0.5 66-56 56-46
0.5 - 5.0 56 46
5.0 - 30.0 60 50
(2) Radiated Emission Requirement
For unintentional device, according to §15.109(a), except for Class A digital devices, the
field strength of radiated emissions from unintentional radiators at a distance of 3 meters
shall not exceed the following values:
Frequency
MHz
Distance
Meters
Radiated
dBμV/m
Radiated
μV/m
30 - 88 3 40.0 100
88 - 216 3 43.5 150
216 - 960 3 46.0 200
Above 960 3 54.0 500
For intentional device, according to §15.209(a), the general requirement of field strength
of radiated emissions from intentional radiators at a distance of 3 meters shall not exceed
the above table.
ETC Report No. : 16-09-RBF-027 Sheet 4 of 36 Sheets
FCC ID: 2AC96WDP

For intentional radiator device, per §15.249(a), the field strength of emissions shall
comply with the following :
Frequency
MHz
Distance
Meters
Fundamental
dBμV/m mV/m
Harmonic
dBμV/m μV/m
902 - 928 3 94 50 54 500

5725 - 5875 3 94 50 54 500
24000 - 24250 3 108 250 68 2500
In accordance with §15.249(e), limits shown in above table are based on average limits
for frequencies above 1000 MHz, and frequencies below 1000 MHz are based on quasi
peak. However, the peak field strength of any emission shall not exceed the maximum
permitted average limits by more than 20 dB.
(3) Spurious in Out Band Requirement
For intentional device, according to §15.249 (d), emissions radiated outside of the
specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB
below the level of fundamental or to the general radiated emission limits in §15.209.
(4) Antenna Requirement
For intentional device, according to §15.203, an intentional radiator shall be designed to
ensure that no antenna other than that furnished by the responsible party shall be used
with the device.
