Test Result: PASS
15.1 Test Procedure:

1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port
to the spectrum.
2. Set the spectrum analyzer:
U-NII-1
RBW = 1MHz, VBW ≥3* RBW Sweep = auto; Detector Function = Peak. Trace = Max hold.
U-NII-3
RBW = 510KHz, VBW ≥3* RBW Sweep = auto; Detector Function = Peak. Trace = Max hold.
3. Allow the trace to stabilize. Use the marker-delta function to determine the separation between the
peaks of the adjacent channels. The limit is specified in one of the subparagraphs of this Section
Submit this plot.

* All transmit signals are completely uncorrelated with each other, Directional gain = GANT which is less than
6dBi. So the limit does not be reduced.

16 Frequency Stability
Test Requirement: FCC CFR47 Part 15 Section 15.407(g)
Test Method: ANSI C63.10:2013
Manufacturers of U-NII devices are responsible for ensuring
Test Limit: frequency stability such that an emission is maintained within the
band of operation under all conditions of normal operation as
specified in the users manual or 20ppm.
Test Result: PASS
16.1 Test Procedure:

1. The transmitter output (antenna port) was connected to the spectrum analyzer.
EUT have transmitted absence of unmodulation signal and fixed channelise. Set the
spectrum analyzer span to view the entire absence of modulation emissions
bandwidth. Set RBW = 10 kHz, VBW = 10 kHz with peak detector and maxhold
settings. fc is declaring of channel frequency. Then the frequency error formula is
(fc-f)/fc × 106 ppm and the limit is less than ±20ppm The test extreme voltage is to change
the primary supply voltage from 85 to 115 percent of the nominal value.

2. Extreme temperature rule is -15°C~ 45°C.

17 Antenna 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.
This device uses of two antennas that uses a specified coupling to the intentional radiator. Antenna
connectors complied with the requirement.
