6. Measurements, Examination And Derived Results
6.1 Antenna Requirement
Applicable Standard
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. 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 user of a standard antenna jack or electrical connector is prohibited.
The structure and application of the EUT were analyzed to determine compliance with section §15.203 of the
rules. §15.203 state that the subject device must meet the following criteria:
a. Antenna must be permanently attached to the unit.
b. Antenna must use a unique type of connector to attach to the EUT.
Unit must be professionally installed, and installer shall be responsible for verifying that the correct antenna
is employed with the unit.
And according to FCC 47 CFR section 15.247 (b), if the 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 6 dBi.
Antenna Connector Construction
The EUT has 1 antenna:
A permanently attached PCB antenna for BLE, the gain is 0dBi for BLE.
The antenna meets up with the ANTENNA REQUIREMENT.
Result: Compliance.

1. Check the calibration of the measuring instrument using either an internal
calibrator or a known signal from an external generator.
2. Position the EUT without connection to measurement instrument. Put it on the
Rotated table and turn on the EUT and make it operate in transmitting mode. Then
set it to Low Channel and High Channel within its operating range, and make sure
the instrument is operated in its linear range.

Test Setup
1.
The EUT was switched on and allowed to warm up to its normal operating condition.
2.
The test was carried out at the selected frequency points obtained from the EUT
characterization. Maximization of the emissions, was carried out by rotating the EUT,
changing the antenna polarization, and adjusting the antenna height in the following
manner:
a.
Vertical or horizontal polarization (whichever gave the higher emission level
over a full rotation of the EUT) was chosen.
b.
Procedure
The EUT was then rotated to the direction that gave the maximum
emission.
c.
Finally, the antenna height was adjusted to the height that gave the maximum
emission.
3.
The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is
120 kHz for Quasiy Peak detection at frequency below 1GHz.
4.
The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video
bandwidth is 3MHz with Peak detection for Peak measurement at frequency above
1GHz.
Test Report No.
18070212-FCC-R
Page
27 of 37
The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video
bandwidth is 10Hz with Peak detection for Average Measurement as below at
frequency above 1GHz.
5.
Steps 2 and 3 were repeated for the next frequency point, until all selected frequency
points were measured.
