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 LPRX4X30 (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
to CISPR quasi-peak and average detectors with a 9kHz resolution bandwidth for final measurements.
Line conducted emissions test results are shown in Section 7.6. The EMI Receiver mode of the Agilent MXE was
used to perform AC line conducted emissions testing.

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).

Test Setup
The EUT and measurement equipment were set up as shown in the diagram below.
Figure 7-4. Radiated Test Setup
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)2 = 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.
6. All measurements were recorded using a spectrum analyzer employing a quasi-peak detector.
7. The "-" shown in the following RSE tables are used to denote a noise floor measurement.
Sample Calculation
Field Strength Level [dBµV/m] = Analyzer Level [dBm] + 107 + AFCL [dB/m]
AFCL [dB/m] = Antenna Factor [dB/m] + Cable Loss [dB]
