Measurements

All tests performed with a calibrated Vector Network Analyzer (VNA) and 36 dB attenuator. Worst-case harmonic: −42.33 dBc (3rd), exceeding ETSI EN 300 220 (≥40 dB below carrier for ≤30 dBm TX), giving >3 dB margin. Spectrum analysis confirms excellent spurious suppression and clean transmission within 12.5 kHz bandwidth.

Performance is comparable to leading brands and fully compliant with CE RED and international standards.
