Summary of Test Results
| FCC Rules | Description of Test | Result |
|---|---|---|
| §15.203 | Antenna Requirement | Compliant |
| §15.207(a) | Conduction Emissions | Not Applicable |
| §15.205, §15.209, §15.249 | Radiated Emissions & Out of Band Emission | Compliant |
| §15.215 (c) | 20 dB Bandwidth | Compliant |
Note: The EUT is a battery-operated device.
FCC§15.203 - Antenna Requirement
The EUT has a PCB antenna with an antenna gain of 0 dBi, which is permanently attached, fulfilling the requirement.
Result: Compliant.
FCC§15.205, §15.209&§15.249 - Radiated Emissions & Out of Band Emission
The field strength of emissions from intentional radiators operated within the specified frequency bands comply with the following limits:
| Fundamental frequency | Field strength of fundamental (millivolts/meter) | Field strength of harmonics (microvolts/meter) |
|---|---|---|
| 902-928 MHz | 50 | 500 |
| 2400-2483.5 MHz | 50 | 500 |
| 5725-5875 MHz | 50 | 500 |
| 24.0-24.25 GHz | 250 | 2500 |
Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in §15.209, whichever is the lesser attenuation.
EUT Setup (Below 1 GHz): A diagram shows the EUT on a non-conductive table 80cm above the ground plane, with a turntable of 2m diameter, and an antenna tower at 1.5 meters distance.
EUT Setup (Above 1 GHz): A diagram shows the EUT on a non-conductive table 150cm above the ground plane, with a turntable of 2m diameter, and an antenna tower at 1.5 meters distance.
The radiated emission and out-of-band emission tests were performed in a 3-meter chamber test site, in accordance with ANSI C63.10-2013, FCC 15.209/15.205, and FCC 15.249 limits.
Test Equipment Setup:
| Frequency Range | RBW | Video B/W | IF B/W | Detector |
|---|---|---|---|---|
| 30 MHz - 1000 MHz | 120 kHz | 300 kHz | 120 kHz | QP |
| Above 1GHz | 1MHz | 3 MHz | / | PK |
| Above 1GHz | 1MHz | 3 MHz | / | Ave |
Test Procedure: Maximizing procedure was performed on the highest emissions to ensure EUT compliance. Data was recorded in Quasi-peak detection mode (30MHz-1GHz) and Peak/Average detection mode (above 1 GHz).
Corrected Amplitude & Margin Calculation: Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss - Amplifier Gain. Margin = Limit – Corrected Amplitude.
Test Results Summary: The EUT complied with FCC Part 15.209 &15.205 & 15.249.
