A Handbook For EMC Testing and Measurement

| For communications equipment | |
| (a) | AM receivers: modulate with 50% 1 kHz sinusoid |
| (b) | FM receivers: When monitoring signal-to-noise ratio, modulate with 1 kHz signal and 10 kHz deviation |
| (c) | SSB receivers: No modulation |
| (d) | Other equipments: As for AM receivers |
| Equipments with video channels: | |
| Use 90 ?100% pulse modulation with duration of 2 /BW and repetition rate of BW/1000, where BW = video bandwidth | |
| Digital equipment: | |
| Use pulse modulation with pulse duration and repetition rates equal to that used in equipment | |
| Nontuned equipment: | |
| AM at 50% with 1 kHz sinusoid |
| Susceptibility frequency | Modulation type | |
