10Vrms applied over frequency range 150kHz to 100MHz.
Additional spot tests at 27 and 68MHz.
Varying voltages applied in common mode as follows:
15Hz to 150Hz: 10V → 1Vrms (20dB/decade)
150Hz to 1.5kHz: 1Vrms
1.5kHz to 15kHz: 1 → 10Vrms (20dB/decade)
15kHz to 150kHz: 10Vrms
300V 50Hz for 10s applied to ports in common mode.
100V 50Hz for 10s applied to ports in differential mode.
Not applicable to AC inputs.
