CE-Red spurious emission test
All measurements were conducted using a calibrated Vector Network Analyzer (VNA) and a calibrated 36 dB attenuator. The worst-case harmonic observed was the third harmonic, measured at -73.6 dBc. This performance exceeds the requirements set by the CE RED directive for devices with output power below 30 dBm. Specifically, ETSI EN 300 220 requires spurious emissions to be at least 43 dB below the carrier power for transmitters up to 30 dBm. Our device comfortably meets and surpasses this standard, offering an additional safety margin of over 30 dB.
Our measured spurious emission levels of -73.6 dBc clearly demonstrate superior spectral purity.
This level of performance ensures compliance with international standards and places our device in the same league as the most respected brands in the market.
