Test Results Summary
All tested parameters met the specified requirements. The EUT passed all conducted and radiated emission tests.
Conducted Testing at Antenna Port
- Antenna Requirement: The EUT uses an integrated PCB antenna with a gain of -1.09 dBi, complying with FCC 15.203, 15.204, and RSS-Gen 6.4/6.8 requirements.
- 6dB & 99% Bandwidth: The EUT's bandwidth was measured across different channels (2405MHz, 2445MHz, 2480MHz). Graphs illustrate these bandwidths, with results indicating compliance.
- Output Power: Peak conducted output power measurements for channels 2405MHz, 2445MHz, and 2480MHz were recorded, all within the 30 dBm limit.
- Power Spectral Density: Measurements for power spectral density at 2405MHz, 2445MHz, and 2480MHz were performed. Graphs show the spectral density plots, with results below the 8.0 dBm limit.
- Conducted Band Edge and out-of Band Emissions: Tests confirmed compliance with band edge and out-of-band emission limits. Graphs illustrate these measurements.
Emission in the Frequency Range up to 30MHz
- Conducted Emission: Testing for conducted emissions on Line (L) and Neutral (N) lines was performed. Graphs and tables show that measured emissions were below the specified limits (QuasiPeak and Average).
Emission in the Frequency Range above 30MHz
- Radiated Band-Edge: Radiated band-edge emissions were measured for channels 2405MHz and 2480MHz in both horizontal (H) and vertical (V) polarizations. Graphs demonstrate compliance with the limits.
- Radiated Spurious Emission: Radiated spurious emissions were tested across various frequency ranges (30MHz to 18GHz). Graphs for 2405MHz, 2445MHz, and 2480MHz show compliance. For the frequency range from 18GHz to 25GHz, no emission was found. Detailed tables for QuasiPeak (QP), Peak (PK), and Average (AV) measurements across different frequencies confirm that all results were within the specified limits.
Test Equipment and Methodology
Testing was conducted using calibrated equipment from manufacturers like Rohde & Schwarz and Schwarzbeck. Measurement uncertainty for conducted and radiated emissions was determined and is available upon request.
The test facilities used are accredited and registered with regulatory bodies such as the FCC and Innovation, Science and Economic Development Canada.
