General Test Procedures
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.

Radiated Emissions Table
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 broadband 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 and a 1.5m table height. 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.

Conducted Emissions Test Setup and Procedures
Battery Power Conducted Spurious The EUT is not subject to measurement of power line conducted emissions
as it is powered solely by its internal battery.
4.1.3
Power Supply Variation
Tests at extreme supply voltages are made if required by the the procedures specified in the test standard, and results
of this testing are detailed in this report.
In the case the EUT is designed for operation from a battery power source, the extreme test voltages are evaluated
over the range specified in the test standard; no less than ±10% of the nominal battery voltage declared by the
manufacturer. For all battery operated equipment, worst case intentional and spurious emissions are re-checked
employing a new (fully charged) battery.

Fundamental Emission Bandwidth
Test Setup & Procedure The test equipment and facilities were setup in accordance with the standards and
procedures listed in Section 2.1. Environmental conditions were set at the appropriate temperature and thermal
balance was checked with a thermocouple based probe. Emission bandwidth (EBW) of the EUT is measured with
the device placed in the test mode(s) with the shortest available frame length and minimum frame spacing. The
20 dB EBW is measured as the max-held peak-detected signal when the IF bandwidth is greater than or equal to
1% of the receiver span. For complex modulations other than ASK and FSK, the 99% emission bandwidth per IC
test procedures has a different result, and is also reported. The test equipment employed includes RSFSV30001,
BILOG3142.
Measurement Results The details and results of testing the EUT are summarized in Table 5. Plots showing the

Test Setup & Procedure The test equipment and facilities were setup in accordance with the standards and
procedures listed in Section 2.1. Environmental conditions were set at the appropriate temperature and thermal
balance was checked with a thermocouple based probe. Spurious radiated emissions measurements are performed to
10 times the highest fundamental operating frequency. The test equipment employed includes HP8546A, BILOG3142,
RH3115.
Measurement Results
The details and results of testing the EUT are summarized in Table 7.

Radiated Digital Spurious
The results for the measurement of digital spurious emissions are not reported herein as all digital emissions were
greater than 20 dB below the regulatory limit. Radiation from digital components was measured to 4 GHz, or to
five times the maximum digital component operating frequency, whichever is greater.
