instrument, antenna and the closest point of any part of the device
or system.

3.3.Test Procedure
ANSI STANDARD C63.4-2009 10.1.7 MEASUREMENT PROCEDURES:

The EUT is placed on a turned table that is 0.8 meter above the ground. The
turned table can rotate 360 degrees to determine the position of the
maximum emission level. The EUT is set 3 meters away from the receiving
antenna that is mounted on the antenna tower. The antenna can move up
and down between 1 meter and 4 meters to find out the maximum emission
level. Broadband antenna (log periodical antenna and horn antenna) is used
as receiving antenna. Both horizontal and vertical polarization of the antenna
is set on test.
The resolution bandwidth was 100 kHz and the video bandwidth was 300
kHz.
The spectrum was scanned from 30 MHz to 10th harmonic of the
fundamental.

4. BANDWIDTH

4.1.Test Standard
FCC Part 15 Subpart C Section 15.231

4.2.Limits
(0.0025*433.92MHz=1084.8KHz)

192KHz<1084.8KHz

4.3.Test Procedure
(1) Turn on the transmitter, and set it to transmit the pulse train continuously.
(2) Set Test Receiver into spectrum analyzer mode, Tune the spectrum
analyzer to the transmitter carrier frequency, and set the spectrum
analyzer resolution bandwidth(RBW) to 100kHz and video
bandwidth(VBW) to 100kHz, then select Peak function to scan the
channel frequency.
(3) The 20dB bandwidth was measured and recorded.
Maximizing procedure was performed on the highest emissions to ensure
that the EUT complied with all installation combinations.

4.4.Test Result

PASS

5. DUTY CYCLE

5.1.Test Standard
15.231

5.2.Test Procedure
(1) The EUT was placed on a turntable which is 0.8m above ground plane.

(2) Set EUT operating in continuous transmitting mode

(3) Set Test Receiver into spectrum analyzer mode, Tune the spectrum analyzer to the
transmitter carrier frequency, and set the spectrum analyzer resolution bandwidth(RBW)
to 100kHz and video bandwidth(VBW) to 300kHz, Span was set to 0Hz.
(4) The Duty Cycle was measured and recorded.

5.3.Test Result
Test plots see following pages
20log(Duty cycle)= 20log(12*1.31ms+13*0.46ms/67.46ms)=-9.85dB

Note: because the pulse emission bandwidth is less than measuring bandwidth,
so the PDCF is not need

6. ANTENNA REQUIREMENT
Requirement(s): 47 CFR §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.
Antenna requirement must meet at least one of the following:
a) Antenna must be permanently attached to the device.
b) Antenna must use a unique type of connector to attach to the device.
c) Device must be professionally installed. Installer shall be responsible
for ensuring that the correct antenna is employed with the device.
The antenna is integral antenna. Antenna maximum gain is 0dBi.
According to Section 15.203, an intentional radiator shall be designed to
