DETAILED RESULTS
4.1
DUTY CYCLE
Test Method:
ANSI C63.10:2013, Section 7.5
Limits for duty cycle:
As shown in 15.35(b), for frequencies above 1000MHz, the field strength limits are based on average
detector, however, the peak field strength of any emission shall not exceed the maximum permitted
average limits by more than 20dB under any condition of modulation.
(c) Unless otherwise specified, e.g., §§15.255(b), and 15.256(l)(5), when the radiated emission limits
are expressed in terms of the average value of the emission, and pulsed operation is employed, the
measurement field strength shall be determined by averaging over one complete pulse train,
including blanking intervals, as long as the pulse train does not exceed 0.1 seconds. As an alternative
(provided the transmitter operates for longer than 0.1 seconds) or in cases where the pulse train
exceeds 0.1 seconds, the measured field strength shall be determined from the average absolute
voltage during a 0.1 second interval during which the field strength is at its maximum value. The exact
method of calculating the average field strength shall be submitted with any application for
certification or shall be retained in the measurement data file for equipment subject to Supplier's
Declaration of Conformity.
Test procedures:
Because the EUT did not have provisions for making conducted measurements, the duty cycle was
measured in a 10m semi-anechoic chamber with the test receiver set to “Zero span” mode.
All field strength or power measurements shown in these plots are arbitrary and only the times and
levels of the EUT relative to the remote are considered for compliance.
Deviations from test standard:
No deviation.

Figure 1 - Radiated Emissions Test Setup
EUT operating conditions:
The EUT was powered by 18 VDC unless specified. The duty cycle was only tested on the lowest
channel as it will be identical for all channels.
The EUT will only transmit when triggered by a paired remote. In order to measure the maximum
possible duty cycle in a user application, a button was held down on the remote.

Test procedures:
a. The EUT was placed on the top of a rotating table above the ground plane in a 10 meter
semi-anechoic chamber. The table was rotated 360 degrees to determine the position of the
highest radiation. The table was 0.8m high for measurements form 30MHz-1Ghz and 1.5m
for measurements from 1GHz and higher.
b. The EUT was set 3 meters away from the interference-receiving antenna, which was
mounted on the top of a variable-height antenna tower.
c. The antenna was a broadband antenna, and its height is varied from one meter to four
meters above the ground to determine the maximum value of the field strength. Both
horizontal and vertical polarizations of the antenna are used to make the measurement.
d. For each suspected emission, the EUT was arranged to maximize its emissions and then
the antenna height was varied from 1 meter to 4 meters and the rotating table was turned
from 0 degrees to 360 degrees to find the maximum emission reading.
e. The test-receiver system was set to use a peak detector with a specified resolution
bandwidth. For spectrum analyzer measurements, the composite maximum of several
analyzer sweeps was used for final measurements.
f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then
testing could be stopped and the peak values of the EUT would be reported. Otherwise the
emissions that did not have 10 dB margin would be re-tested one by one using peak, quasipeak or average method as specified and then reported in a data sheet.
g. The EUT was maximized in all 3 orthogonal positions. The results are presented for the
axis that had the highest emissions.

REMARKS:
1. Emission level (dBuV/m) = Raw Value (dBuV) + Correction Factor (dB)
2. Correction Factor (dB/m) = Antenna Factor (dB/m) + Cable Factor (dB)
3. The other emission levels were very low against the limit.
4. Margin value = Emission level – Limit value.
5. The EUT was measured in all 3 orthagonal axis. It was found that the Y-axis produced the highest
emissions, and this orientation was used for all testing. See the test setup photo exhibit for details on the
orientations.
6. The axis shown in the last column of the data tables shows the axis where the emissions were found to be
the highest.

BANDWIDTH
Test Method: ANSI C63.10, Section(s) 11.8.1
Limits of bandwidth measurements:
The 6dB bandwidth of the signal must be greater than 500 kHz.
Test procedures:
Bandwidth measurement was taken at a distance of 3m from the EUT. The bandwidth of the
fundamental frequency was measured by spectrum analyzer with 100 kHz RBW and 300 kHz
VBW.
The 99% occupied is defined as the bandwidth at which 99% of the signal power is found.
This corresponds to 20dB down from the maximum power level. The maximum power was
measured with the largest resolution bandwidth possible (10MHz) and this value was
recorded. The signal was then captured with a 1 MHz resolution bandwidth and the
frequencies where the measurements were 20dB below the maximum power were marked.
The bandwidth between these frequencies was recorded as the 99% occupied bandwidth.
The 6 dB bandwidth is defined as the bandwidth of which is higher than peak power minus
6dB.
Deviations from test standard:
No deviation.

BANDEDGES
Test Method:
ANSI C63.10, Section(s) 6.10.6, 11.13.2
Limits of bandedge measurements:
For emissions outside of the allowed band of operation (2400.0MHz – 2480.0MHz), the
emission level needs to be 20dB under the maximum fundamental field strength. However, if
the emissions fall within one of the restricted bands from 15.205 the field strength levels need
to be under that of the limits in 15.209.
Test procedures:
The EUT was tested in the same method as described in section 4.3 - Bandwidth. The EUT
was oriented as to produce the maximum emission levels. The resolution bandwidth was set
to 30kHz and the EMI receiver was used to scan from the bandedge to the fundamental
frequency with a quasi-peak detector. The highest emissions level beyond the bandedge
was measured and recorded. All band edge measurements were evaluated to the general
limits in Part 15.209.
Deviations from test standard:
No deviation.
Test setup:
See Section 4.3
EUT operating conditions:
The EUT was powered by 18 VDC unless specified and set to transmit continuously on the
lowest frequency channel, highest frequency channel and one in the middle of its operating
range.

APPENDIX A - SAMPLE CALCULATION
Field Strength Calculation
The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier
Gain (if any) from the measured reading. The basic equation with a sample calculation is as follows:
FS = RA + AF – (-CF + AG) + AV
where FS = Field Strength
RA = Receiver Amplitude
AF = Antenna Factor
CF = Cable Attenuation Factor
AG = Amplifier Gain
AV = Averaging Factor (if applicable)
Assume a receiver reading of 55 dBV is obtained. The Antenna Factor of 12 and a Cable Factor of 1.1 is
added. The Amplifier Gain of 20 dB is subtracted, giving a field strength of 48.1 dBV/m.
FS = 55 + 12 – (-1.1 + 20) + 0 = 48.1 dBV/m
The 48.1 dBV/m value can be mathematically converted to its corresponding level in V/m.
Level in V/m = Common Antilogarithm [(48.1 dBV/m)/20]= 254.1 V/m
AV is calculated by the taking the 20*log(T on/100) where Ton is the maximum transmission time in any 100ms
window.

EIRP Calculations
In cases where direct antenna port measurement is not possible or would be inaccurate, output power is
measured in EIRP. The maximum field strength is measured at a specified distance and the EIRP is
calculated using the following equation;
EIRP (Watts) = [Field Strength (V/m) x antenna distance (m)] / 30
Power (watts) = 10^[Power (dBm)/10] / 1000
Voltage (dBµV) = Power (dBm) + 107 (for 50Ω measurement systems)
Field Strength (V/m) = 10^[Field Strength (dBµV/m) / 20] / 10^6
Gain = 1 (numeric gain for isotropic radiator)
Conversion from 3m field strength to EIRP (d=3):
EIRP = [FS(V/m) x d^2]/30 = FS [0.3]
for d = 3
EIRP(dBm) = FS(dBµV/m) – 10(log 10^9)+ 10log[0.3] = FS(dBµV/m) - 95.23
10log( 10^9) is the conversion from micro to milli
