IEC 60315-3: Radio Receiver Measurements — Sensitivity and SINAD Testing

What “1 μV Sensitivity” Means: SINAD 12dB Standard Test Conditions

IEC 60315-3:1999 specifies radio receiver measurement methods. Sensitivity is the minimum input signal for SINAD=(S+N+D)/(N+D)=12dB. SINAD accounts for both noise and distortion — FM demodulation nonlinearity is non-negligible.

TNLab — Receiver sensitivity is the “first kilometre” — determining whether signal can be heard above noise.
