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 oor standing, the congurations 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 conguration. See Figure 3. All intentionally radiating elements that are not xed-mounted in use are placed on the test table lying at, on their side, and on their end

(3-axes) and the resulting worst case emissions are recorded. If the EUT is xed-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-eld 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 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 eld strength, power values (dBm) measured on the test receiver / analyzer are converted to dBV/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-amplier 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 specied at alternate distance) in dB. This eld strength value is then compared with the regulatory limit. If eective isotropic radiated power (EIRP) is computed, it is computed as EIRP (dBm) = E3m(dBV /m) 95.2.

Conducted transmit chain emissions measurements (where applicable) are made by connecting the EUT antenna port directly to the test receiver port. Photographs of the test setup employed are depicted in Figure 5. Figure 5: Conducted RF Test Setup Photograph(s). 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 procedures specied 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 specied 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.

Where the EUT is not sold with an antenna connector, a modied product has been provided including such. Peak conducted output power was measured directly from the EUT at the port where the antenna attaches. The test receiver bandwidth was set to be greater than the measured emission bandwidth of the EUT to capture the true peak. Antenna gain is either provided directly by the antenna manufacturer or measured by comparison between calculated EIRP and conducted output power. Table 6 details the results of these measurements. Plots showing conducted measurements made are depicted in Figure 8. Table 6: Radiated Power Results.
