3.0              DESCRIPTION OF TEST

3.1           Evaluation Procedure
The measurement procedure described in the American National Standard of Procedures for Compliance Testing
of Unlicensed Wireless Devices (ANSI C63.10-2013) was used in the measurement of the EUT.

Deviation from measurement procedure…………………………………………….....................................None

3.2           AC Line Conducted Emissions
The line-conducted facility is located inside a 10'x16'x9' shielded enclosure. The shielded enclosure is
manufactured by ETS Lindgren RF Enclosures. The shielding effectiveness of the shielded room is in accordance
with MIL-Std-285 or NSA 65-5. A 1m x 1.5m wooden table 80cm high is placed 40cm away from the vertical wall
and 80cm away from the sidewall of the shielded room. Two 10kHz-30MHz, 50Ω/50µH Line-Impedance
Stabilization Networks (LISNs) are bonded to the shielded room floor. Power to the LISNs is filtered by external
high-current high-insertion loss power line filters. The external power line filter is an ETS Lindgren Model LPRX-
4X30 (100dB Attenuation, 14kHz-18GHz) and the two EMI/RFI filters are ETS Lindgren Model LRW-2030-S1
(100dB Minimum Insertion Loss, 14kHz – 10GHz). These filters attenuate ambient signal noise from entering the
measurement lines. These filters are also bonded to the shielded enclosure.

The EUT is powered from one LISN and the support equipment is powered from the second LISN. If the EUT is a
DC-powered device, power will be derived from the source power supply it normally will be powered from and this
supply line(s) will be connected to the second LISN. All interconnecting cables more than 1 meter were shortened
to a 1 meter length by non-inductive bundling (serpentine fashion) and draped over the back edge of the test
table. All cables were at least 40cm above the horizontal reference groundplane. Power cables for support
equipment were routed down to the second LISN while ensuring that that cables were not draped over the second
LISN.

Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them to warm up to
their normal operating condition. The RF output of the LISN was connected to the spectrum analyzer and
exploratory measurements were made to determine the frequencies producing the maximum emission from the
EUT. The spectrum was scanned from 150kHz to 30MHz with a spectrum analyzer. The detector function was set
to peak mode for exploratory measurements while the bandwidth of the analyzer was set to 10kHz. The EUT,
support equipment, and interconnecting cables were arranged and manipulated to maximize each emission. Once
the worst case emissions have been identified, the one EUT cable configuration/arrangement and mode of
operation that produced these emissions is used for final measurements on the same test site. The analyzer is set

3.3           Radiated Emissions
The radiated test facilities consisted of an indoor 3 meter semi-anechoic chamber used for final measurements
and exploratory measurements, when necessary. The measurement area is contained within the semi-anechoic
chamber which is shielded from any ambient interference. The test site inside the chamber is a 6m x 5.2m
elliptical, obstruction-free area in accordance with Figure 5.7 of Clause 5 in ANSI C63.4-2014. Absorbers are
arranged on the floor between the turn table and the antenna mast in such a way so as to maximize the reduction
of reflections for measurements above 1GHz. An 80cm tall test table made of Styrodur is placed on top of the turn
table. For measurements above 1GHz, an additional Styrodur pedestal is placed on top of the test table to bring
the total table height to 1.5m.

For all measurements, the spectrum was scanned through all EUT azimuths and from 1 to 4 meter receive
antenna height using a broadband antenna from 30MHz up to the upper frequency shown in 15.33 depending on
the highest frequency generated or used in the device or on which the device operates or tunes. For frequencies
above 1GHz, linearly polarized double ridge horn antennas were used. For frequencies below 30MHz, a
calibrated loop antenna was used. When exploratory measurements were necessary, they were performed at 1
meter test distance inside the semi-anechoic chamber using broadband antennas, broadband amplifiers, and
spectrum analyzers to determine the frequencies and modes producing the maximum emissions. Sufficient time
for the EUT, support equipment, and test equipment was allowed in order for them to warm up to their normal
operating condition. The test set-up was placed on top of the 1 x 1.5 meter table. The EUT, support equipment,
and interconnecting cables were arranged and manipulated to maximize each emission. Appropriate precaution
was taken to ensure that all emissions from the EUT were maximized and investigated. The system configuration,
mode of operation, turntable azimuth, and receive antenna height was noted for each frequency found.

Final measurements were made in the semi-anechoic chamber using calibrated, linearly polarized broadband and
horn antennas. The test setup was configured to the setup that produced the worst case emissions. The spectrum
analyzer was set to investigate all frequencies required for testing to compare the highest radiated disturbances
with respect to the specified limits. The turntable containing the EUT was rotated through 360 degrees and the
height of the receive antenna was varied 1 to 4 meters and stopped at the azimuth and height producing the
maximum emission. Each emission was maximized by changing the orientation of the EUT through three
orthogonal planes and changing the polarity of the receive antenna, whichever produced the worst-case
emissions.

3.4           Environmental Conditions
The temperature is controlled within range of 15oC to 35oC. The relative humidity is controlled within range of 10%
to 75%. The atmospheric pressure is monitored within the range 86-106kPa (860-1060mbar).

7.3           Frequency Stability Test Data
§15.225; RSS-210 (B.6)

Test Overview and Limit

Frequency stability testing is performed in accordance with the guidelines of ANSI C63.10-2013. The frequency
stability of the transmitter is measured by:

a.)       Temperature: The temperature is varied from -20°C to +50°C in 10°C increments using an environmental
          chamber.

b.)       Primary Supply Voltage: The primary supply voltage is varied from 85% to 115% of the nominal value for
          non hand-carried battery and AC powered equipment. For hand-carried, battery-powered equipment,
          primary supply voltage is reduced to the battery operating end point which shall be specified by the
          manufacturer.

For Part 15.225, the frequency stability of the transmitter shall be maintained within ±0.01% of the center
frequency.

Test Settings

      1. The carrier frequency of the transmitter is measured at room temperature (20°C to provide a reference).
      2. The equipment is turned on in a “standby” condition for fifteen minutes before applying power to the
         transmitter. Measurement of the carrier frequency of the transmitter is made within one minute after
         applying power to the transmitter.
      3. Frequency measurements are made at 10°C intervals ranging from -20°C to +50°C. A period of at least
         one half-hour is provided to allow stabilization of the equipment at each temperature level.

Test Setup

The EUT was connected via an RF cable to a spectrum analyzer with the EUT placed inside an environmental
chamber.

Test Notes

None.

7.4           In-Band Radiated Spurious Emission Measurements
§15.225(a)(b)(c); RSS-210 (B.6)

Test Overview and Limit

The EUT was tested from 13.110 – 14.010 MHz. All in-band radiated spurious emissions are measured with a
spectrum analyzer connected to a loop antenna while the EUT is operating at appropriate frequencies. Only the
radiated emissions of the configuration that produced the worst case emissions are reported in this section.

All in-band emissions appearing in a restricted band as specified in Section 15.225 of the Title 47 CFR
must not exceed the limits shown in Table 7-4.

Test Notes:

1.    All emissions lying in restricted bands specified in §15.225 and RSS—210 are below the limit shown in Table
      7—4.
2.    All measurements were performed using a loop antenna. The antenna was positioned in three orthogonal
      positions (X front, Y side, Z top) and the position with the highest emission level was recorded.
3.    The EUT was positioned in three orthogonal planes to determine the orientation resulting in the worst case
       emissions.
4.    Measurements were performed at 3m and the data was extrapolated to the specified measurement distance
       of 30m using the square of an inverse linear distance extrapolation factor (40 dB/decade) as specified in
       §15.31(f)(2). Extrapolation Factor = 20 log10(30/3) = 40dB.
5..   The spectrum was investigated from 9kHz up to 30MHz using the loop antenna. Only the emissions shown in
      the table below were found to be significant.
      All measurements were recorded using a spectrum analyzer employing a quasi—peak detector.
      The "—" shown in the following RSE tables are used to denote a noise floor measurement.

7.5           Radiated Spurious Emission Measurements, Out-of-Band
§15.209 §15.225(d); RSS-Gen (8.9)

Test Overview and Limit

The EUT was tested from 9kHz up to the 1GHz excluding the band 13.110 – 14.010 MHz. All measurements up
to 960MHz were recorded with a spectrum analyzer employing a quasi-peak detector.

All out-of-band emissions appearing in a restricted band as specified in Section 15.225 of the Title 47
CFR must not exceed the limits shown in Table 7-6 per Section 15.209.

                                                                                  Field Strength                           Measured Distance

Test Notes:

      1. All measurements were recorded using a spectrum analyzer employing a quasi-peak detector for
             emissions below 960MHz.
      2. A loop antenna was used to investigate emissions below 30MHz.
      3. Both Vertical and Horizontal polarities of the receive antenna were evaluated with the worst case
             emissions being reported. Below 30MHz the loop antenna was positioned in 3 orthogonal planes (X front,
             Y side, Z top) to determine the orientation resulting in the worst case emissions.
      4. The EUT was positioned in three orthogonal planes to determine the orientation resulting in the worst
             case emissions.
      5. The spectrum is measured from 9kHz to the 10th harmonic and the worst-case emissions are reported.
      6. No spurious emissions levels were found to be greater than the level of the fundamental.
      7. The "-" shown in the following RSE tables are used to denote a noise floor measurement.

Sample Calculation

o      Field Strength Level [dBµV/m] = Analyzer Level [dBm] + 107 + AFCL [dB/m]
o      AFCL [dB/m] = Antenna Factor [dB/m] + Cable Loss [dB]
o      Margin [dB] = Field Strength Level [dBµV/m] – Limit [dBµV/m]

§15.207; RSS-Gen (8.8)

Test Overview and Limit

All AC line conducted spurious emissions are measured with a receiver connected to a grounded LISN while the
EUT is operating at its maximum duty cycle, at maximum power, and at the appropriate frequencies. All data rates
and modes were investigated for conducted spurious emissions. Only the conducted emissions of the
configuration that produced the worst case emissions are reported in this section.

All conducted emissions must not exceed the limits shown in the table below, per Section 15.207 and
RSS-Gen (8.8).

Test Notes

1.       All modes of operation were investigated and the worst—case emissions are reported using mid channel.
        The emissions found were not affected by the choice of channel used during testing.
2.      The limit for an intentional radiator from 150kHz to 3OMHz are specified in 15.207 and RSS—Gen (8.8).
3.       Corr. (dB) = Cable loss (dB) + LISN insertion factor (dB)
4.       QP/AV Level (dBuV) = QP/AV Analyzer/Receiver Level (dBuV) + Corr. (dB)

5.       Margin (dB) = QP/AV Limit (dBuV) — QP/AV Level (dBuV)
6.      Traces shown in plot are made using a peak detector.
7.       Deviations to the Specifications: None.
8.       EUT was tested with the antenna terminated.
