4 Emissions
4.1 General Test Procedures
4.1.1 Radiated Test Setup and Procedures
Radiated electromagnetic emissions from the EUT are first pre-scanned in our screen room. Spectrum and modulation
characteristics of all emissions are recorded. Instrumentation, including spectrum analyzers and other test equipment
as detailed in Section 1.8 are employed. After pre-scan, emission measurements are made on the test site of record.
If the EUT connects to auxiliary equipment and is table or floor standing, the configurations prescribed in relevant
test standards are followed. Alternatively, a layout closest to normal use (as declared by the provider) is employed
if the resulting emissions appear to be worst-case in such a configuration. See Figure 3. All intentionally radiating
elements that are not fixed-mounted in use are placed on the test table lying flat, on their side, and on their end
(3-axes) and the resulting worst case emissions are recorded. If the EUT is fixed-mounted in use, measurements are
made with the device oriented in the manner consistent with installation and then emissions are recorded. If the
EUT exhibits spurious emissions due to internal receiver circuitry, such emissions are measured with an appropriate
carrier signal applied.

Figure 3: Radiated Emissions Diagram of the EUT.

For devices with intentional emissions below 30 MHz, a shielded loop antenna and/or E-field and H-Field broad-
band probes are used depending on the regulations. Shielded loops are placed at a 1 meter receive height at the desired
measurement distance. For exposure in this band, the broadband probes employed are 10cm diameter single-axis
shielded transducers and measurements are repeated and summed over three axes.
Emissions between 30 MHz and 1 GHz are measured using calibrated broadband antennas. For both horizontal
and vertical polarizations, the test antenna is raised and lowered from 1 to 4 m in height until a maximum emission
level is detected. The EUT is then rotated through 360o in azimuth until the highest emission is detected. The test
antenna is then raised and lowered one last time from 1 to 4 m and the worst case value is recorded. Emissions
above 1 GHz are characterized using standard gain or broadband ridge-horn antennas on our OATS with a 4 × 5
m rectangle of ECCOSORB absorber covering the OATS ground screen. Care is taken to ensure that test receiver
resolution and video bandwidths meet the regulatory requirements, and that the emission bandwidth of the EUT is
not reduced. Photographs of the test setup employed are depicted in Figure 4.
Where regulations allow for direct measurement of field strength, power values (dBm) measured on the test
receiver / analyzer are converted to dBµV/m at the regulatory distance, using

Edist = 107 + PR + KA − KG + KE − CF

where PR is the power recorded on spectrum analyzer, in dBm, KA is the test antenna factor in dB/m, KG is the
combined pre-amplifier gain and cable loss in dB, KE is duty correction factor (when applicable) in dB, and CF is
a distance conversion (employed only if limits are specified at alternate distance) in dB. This field strength value is
then compared with the regulatory limit. If effective isotropic radiated power (EIRP) is computed, it is computed as

EIRP (dBm) = E3m (dBµV /m) − 95.2.

4.2.3 Fundamental Emission
Following the test procedures listed in Section 2.1, field emissions measurements are made on the EUT for both

axes are (1) aligned along the same axis as the test loop antenna and horizontal with respect to the test site ground
plane, (2) aligned coplanar (in the same plane) with the test antenna and aligned horizontal with respect to the test
site ground plane, and (3) aligned coplanar (in the same plane) with the test antenna and vertical with respect to
the test site ground plane. Table 6 details the results of these measurements.
