4.1
Requirements
4.1.1 Carrier Frequency Separation
Test Procedures(ANSI C63.10-2013 7.8.2)
The carrier frequency separation was measured with a spectrum analyzer connected to
the antenna terminal, while EUT has its hopping function enabled.
After the trace being stable, the reading value between the peaks of the adjacent
channels using the marker-delta function was recorded as the measurement results.
Test Settings :
a) Span = 100 kHz (wide enough to capture the peaks of two adjacent channels)
b) RBW = 9.1 kHz (Start with the RBW set to approximately 30% of the channel spacing;
adjust as necessary to best identify the center of each individual channel)
c) VBW = 91 kHz (≥ RBW)
d) Sweep = auto
e) Detector function = peak
f) Trace

20 dB bandwidth
Test Procedures(ANSI C63.10-2013 6.9.2)
Measure the maximum width of the emission that is constrained by the frequencies
associated with the two outermost amplitude points (upper and lower frequencies) that are
attenuated by20 dB relative to the maximum level measured in the fundamental emission.
Test Procedures(ANSI C63.10-2013 6.9.3)
The occupied bandwidth is the frequency bandwidth such that, below its lower and above its
upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of
the given emission.
Use the 99% power bandwidth function of the instrument and report the measured
bandwidth.
Test Settings :
Center frequency = the highest, middle and the lowest channels
a) Span = 25 kHz (between 2 times and 5 times the OBW)
b) RBW = 300 Hz (1% to 5% of the OBW)

4.1.4 Time of Occupancy (Dwell Time)
Test Procedures(ANSI C63.10-2013 7.8.4)
The dwell time was measured with a spectrum analyzer connected to the antenna terminal,
while EUT has its hopping function enabled.
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 as shown in test setup without connection to measurement
instrument. Turn on the EUT and connect its antenna terminal to measurement
instrument via a low loss cable. Then set it to any one measured frequency within
its operating range and make sure the instrument is operated in its linear range.
3. Adjust the center frequency of spectrum analyzer on any frequency be measured
and set spectrum analyzer to zero span mode. And then, set RBW and VBW of
spectrum analyzer to proper value.
4. Measure the time duration of one transmission on the measured frequency. And
then plot the result with time difference of this time duration.
5. Repeat above procedures until all frequencies measured were complete.
Test Settings:
Center frequency = the highest, middle and the lowest channels
a) Span = zero
b) RBW = 1 kHz (≤ channel spacing)
c) VBW = 3 kHz (≥ RBW)
d) Trace = max hold
e) Detector = peak
g) Sweep = as necessary to capture the entire dwell time per hopping channel

Test Procedures(ANSI C63.10-2013 7.8.5)
The maximum peak conducted output power was measured with a spectrum analyzer
connected to the antenna terminal, while EUT has its hopping function disabled at the
highest, middle and the lowest available channels.
Test Settings:
Center frequency = the highest, middle and the lowest channels
a) Span = 1 MHz (approximately 5 times of the 20 dB bandwidth)
b) RBW = 30 kHz (greater than the 20 dB bandwidth of the emission being measured)
c) VBW = 100 kHz (≥ RBW)
d) Detector = peak

4.1.6 Band-edge
Test Procedures(ANSI C63.10-2013 7.8.6 / ANSI C63.10-2013 7.8.8)
The bandwidth at 20 dB down from the highest inband spectral density was measured with a
spectrum analyzer connected to the antenna terminal, while EUT has its hopping function
disabled at the highest, middle and the lowest available channels.
Test Settings:
Center frequency = the highest, middle and the lowest channels
a) RBW = 100 kHz
b) VBW = 300 kHz (≥ RBW)
c) Span = -

Spectrum Analyzer
Limit :
Band-edge > 20 dBc
Test Results
All conducted emission in any 100 kHz bandwidth outside of the spectrum band was at least
20 dB lower than the highest level of the inband spectral density.
Therefore the applying equipment meets the requirement.

4.1.7 Field Strength of Emissions
Test Location
10 m SAC (test distance :
10 m,
3 m SAC (test distance : 3 m)
3 m)
Test Procedures
1)
2)
In the frequency range of 9 kHz to 30 MHz, magnetic field is measured with Loop
Antenna. The Test Antenna is positioned with its plane vertical at 1m distance from the
EUT. The center of the Loop Test Antenna is 1m above the ground. During the
measurement the Loop Test Antenna rotates about its vertical axis for maximum
response at each azimuth about the EUT.
In the frequency rage above 30 MHz, Bi-Log Test Antenna(30 MHz to 1 GHz) and Horn
Test Antenna(above 1 GHz) are used. Test Antenna is 3m away from the EUT. Test
Antenna height is carried from 1m to 4m above the ground to determine the maximum
value of the field strength. The emissions levels at both horizontal and vertical
polarizations should be tested.
Test Settings:
Frequency Range = 9 kHz ~ 10 GHz (900 MHz 10th harmonic)
a) RBW = 1 MHz for f ≥ 1 GHz, 100 kHz for f < 1 GHz, 9 kHz for f < 30 MHz
b) VBW ≥ RBW
c) Sweep time = auto couple

** Except as provided in 15.209(g).fundamental emissions from intentional radiators
operating under this Section shall not be located in the frequency bands 54-72MHz, 7688MHz, 174-216MHz, 470-806MHz. However, operation within these frequency bands is
permitted under other sections of this Part, e.g.15.231 and 15.241.
Note :
1) For above 1 GHz, the emission limit in this paragraph is based on measurement
instrumentation employing an average detector, measurement using
instrumentation with a peak detector function, corresponding to 20 dB above the
maximum permitted average limit.
2) For above 1 GHz, limit field strength of harmonics : 54 dBuV/[email protected] (AV) and
