Harmonics/Spurious Output
Complies with EN 302077-2 when used in conjunction with filter
having following attenuation specifications:
Critical mask:
fc +/- < 768 kHz: < 1.0 dB
fc +/- 970 kHz: > 15 dB
fc +/- 1.75 MHz: > 45 dB
fc +/- > 3 MHz: > 45 dB
fc +/- > 10 MHz: > 50 dB
Non-critical mask: fc +/- < 768 kHz: < 1.0 dB
fc +/- 970 kHz: > 0 dB
