Radiated Emissions Measurement
 Limit
(a) Except as provided elsewhere in this subpart, the emissions from an intentional radiator shall not
exceed the field strength levels specified in the following table:
(b) In the emission table above, the tighter limit applies at the band edges.
(c) The level of any unwanted emissions from an intentional radiator operating under these general
provisions shall not exceed the level of the fundamental emission. For intentional radiators which
operate under the provisions of other sections within this part and which are required to reduce
their unwanted emissions to the limits specified in this table, the limits in this table are based on the
frequency of the unwanted emission and not the fundamental frequency. However, the level of any
unwanted emissions shall not exceed the level of the fundamental frequency.
(d) The emission limits shown in the above table are based on measurements employing a CISPR
quasi-peak detector except for the frequency bands 9-90 kHz, 110-490 kHz and above 1000 MHz.
Radiated emission limits in these three bands are based on measurements employing an average
detector.
(e) The provisions in §§15.31, 15.33, and 15.35 for measuring emissions at distances other than the
distances specified in the above table, determining the frequency range over which radiated
emissions are to be measured, and limiting peak emissions apply to all devices operated under this
part.
(f) In accordance with §15.33(a), in some cases the emissions from an intentional radiator must be
measured to beyond the tenth harmonic of the highest fundamental frequency designed to be
emitted by the intentional radiator because of the incorporation of a digital device. If measurements
above the tenth harmonic are so required, the radiated emissions above the tenth harmonic shall
comply with the general radiated emission limits applicable to the incorporated digital device, as
shown in §15.109 and as based on the frequency of the emission being measured, or, except for
emissions contained in the restricted frequency bands shown in §15.205, the limit on spurious
emissions specified for the intentional radiator, whichever is the higher limit. Emissions which must
be measured above the tenth harmonic of the highest fundamental frequency designed to be
emitted by the intentional radiator and which fall within the restricted bands shall comply with the
general radiated emission limits in §15.109 that are applicable to the incorporated digital device.
(g) Perimeter protection systems may operate in the 54-72 MHz and 76-88 MHz bands under the
provisions of this section. The use of such perimeter protection systems is limited to industrial,
business and commercial applications.

 Test Procedure
Final radiation measurements were made on a three-meter Semi Anechoic Chamber. The EUT system
was placed on a nonconductive turntable which is 0.8 meters height, top surface 1.0 x 1.5 meter. The
spectrum was examined from 3 Hz to 44 GHz in order to cover the whole spectrum below 10th
harmonic which could generate from the EUT. During the test, EUT was set to transmit continuously.
For measurements below 1 GHz the resolution bandwidth is set to 100 kHz for peak detection
measurements or 120 kHz for quasi-peak detection measurements. Peak detection is used unless
otherwise noted as quasi-peak.
For measurements above 1 GHz the resolution bandwidth is set to 1 MHz, and then the video
bandwidth is set to 1 MHz for peak measurements and 10 Hz for average measurements.
A nonconductive material surrounded the EUT to supporting the EUT for standing on tree orthogonal
planes. At each condition, the EUT was rotated 360 degrees, and the antenna was raised and lowered
from one to four meters to find the maximum emission levels. Measurements were taken using both
horizontal and vertical antenna polarization.
Broadband/Horn Antenna were used in frequency 30MHz to 18 GHz at a distance of 3 meter.
Loop/Horn Antenna was used in frequency 9kHz to 30MHz and 18 to 26.5 GHz at a distance of 1 meter.
All test results were extrapolated to equivalent signal at 3 meters utilizing an inverse linear distance
extrapolation Factor (20dB/decade).
For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than average limit
(that means the emission level in peak mode also complies with the limit in average mode), then testing
will be stopped and peak values of EUT will be reported, otherwise, the emissions will be measured in
average mode again and reported.
Appropriate preamplifiers were used for improving sensitivity and precautions were taken to avoid
overloading or desensitizing the spectrum analyzer. No post – detector video filters were used in the
test.
The spectrum analyzer’s 6 dB bandwidth was set to 1 MHz, and the analyzer was operated in the peak
detection mode, for frequencies both below and up 1 GHz. The average levels were obtained by
subtracting the duty cycle correction factor from the peak readings.
The following procedures were used to convert the emission levels measured in decibels referenced to
1 microvolt (dBuV) into field intensity in microvolt pre-meter (uV/m).
The actual field intensity in decibels referenced to 1 microvolt in to field intensity in microvolt per-meter
(dBuV/m).
Page 12 of 16
Report Number: 1702FR11-01
The actual field is intensity in referenced to 1 microvolt per meter (dBuV/m) is determined
by
algebraically adding the measured reading in dBuV, the antenna factor (dB), and cable loss (dB) and
Subtracting the gain of preamplifier (dB) is auto calculate in spectrum analyzer.
(1) Amplitude (dBuV/m) = FI (dBuV) +AF (dBuV) +CL (dBuV)-Gain (dB)
FI= Reading of the field intensity.
AF= Antenna factor.
CL= Cable loss.
P.S Amplitude is auto calculate in spectrum analyzer.
(2) Actual Amplitude (dBuV/m) = Amplitude (dBuV)-Dis(dB)
The FCC specified emission limits were calculated according the EUT operating frequency and
by following linear interpolation equations:
(a) For fundamental frequency : Transmitter Output < +30dBm
(b) For spurious frequency :
Spurious emission limits = fundamental emission limit /10
Data of measurement within this frequency range without mark in the table above means the reading of
emissions are attenuated more than 20dB below the permissible limits or the field strength is too small
to be measured.
