7.2 RADIO FREQUENCY TEST SETUP 2
The test site semi-anechoic chamber has met the requirement of NSA tolerance 4 dB according to the
standards: ANSI C63.10. The test distance is 3m.The setup is according to the requirements in Section
13.1.4.1 of ANSI C63.10-2013 and CAN/CSA-CEI/IEC CISPR 22.
Below 30MHz:
The EUT is placed on a turntable 0.8 meters above the ground in the chamber, 3 meter away from the
antenna (loop antenna). The Antenna should be positioned with its plane vertical at the specified distance
from the EUT and rotated about its vertical axis for maximum response at each azimuth about the EUT. The
center of the loop shall be 1 m above the ground. For certain applications, the loop antenna plane may also
need to be positioned horizontally at the specified distance from the EUT.
Above 30MHz:
The EUT is placed on a turntable 0.8 meters above the ground in the chamber, 3 meter away from the
antenna. The maximal emission value is acquired by adjusting the antenna height, polarisation and turntable
azimuth. Normally, the height range of antenna is 1 m to 4 m, the azimuth range of turntable is 0° to 360°,
and the receive antenna has two polarizations Vertical (V) and Horizontal (H).
Above 1GHz:
(Note: the FCC’s permission to use 1.5m as an alternative per TCBC Conf call of Dec. 2, 2014.)
The EUT is placed on a turntable 1.5 meters above the ground in the chamber, 3 meter away from the
antenna. The maximal emission value is acquired by adjusting the antenna height, polarisation and turntable
azimuth. Normally, the height range of antenna is 1 m to 4 m, the azimuth range of turntable is 0° to 360°,
and the receive antenna has two polarizations Vertical (V) and Horizontal (H).

8.5.4
Test Procedure
This test is required for any spurious emission that falls in a Restricted Band, as defined in Section 15.205.
It must be performed with the highest gain of each type of antenna proposed for use with the EUT. Use the
following spectrum analyzer settings:
For Above 1GHz:
The EUT was placed on a turn table which is 1.5m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 1 MHz
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
For Below 1GHz:
The EUT was placed on a turn table which is 0.8m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 100 kHz for
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
For Below 30MHz:
The EUT was placed on a turn table which is 0.8m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 9kHz
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
For Below 150KHz:
The EUT was placed on a turn table which is 0.8m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 200Hz
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
Follow the guidelines in ANSI C63.10-2013 with respect to maximizing the emission by rotating the EUT,
measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the
measurement antenna height and polarization, etc. A pre-amp and a high pass filter are required for this
test, in order to provide the measuring system with sufficient sensitivity. Allow the trace to stabilize. The
peak reading of the emission, after being corrected by the antenna factor, cable loss, pre-amp gain, etc., is
the peak field strength, which must comply with the limit specified in Section 15.35(b). Submit this data.
Now set the VBW to 10 Hz, while maintaining all of the other instrument settings. This peak level, once
corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel of the
hopping signal is less than 100 ms, then the reading obtained with the 10 Hz VBW may be further adjusted
by a “duty cycle correction factor”, derived from 20log(dwell time/100 ms), in an effort to demonstrate
compliance with the 15.209 limit. Submit this data.
Repeat above procedures until all frequency measured was complete.

8.7 ANTENNA APPLICATION
8.7.1
Antenna Requirement
Standard
FCC CRF Part 15.203
Requirement
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. The use of a permanently attached antenna or of an antenna
that uses a unique coupling to the intentional radiator shall be
considered sufficient to comply with the provisions of this section. The
manufacturer may design the unit so that a broken antenna can be
replaced by the user, but the use of a standard antenna jack or electrical
connector is prohibited. This requirement does not apply to carrier
current devices or to devices operated under the provisions of §15.211,
§15.213, §15.217, §15.219, or §15.221. Further, this requirement does
not apply to intentional radiators that must be professionally installed,
such as perimeter protection systems and some field disturbance
sensors, or to other intentional radiators which, in accordance with
§15.31(d), must be measured at the installation site. However, the
installer shall be responsible for ensuring that the proper antenna is
employed so that the limits in this part are not exceeded.
For intentional device, according to FCC 47 CFR Section 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. And according to FCC 47 CFR Section 15.247 (b), if transmitting antennas of
directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the
directional gain of the antenna exceeds 6dBi.
8.7.2
Result
This module is suitable for host antennas with gain less than 6dBi. The auxiliary test antenna is metal
antenna.
