professional use - Part 2. Immunity
1 Scope
This Part of GB/T 19554 specifies immunity test requirements, test signals,
performance criteria and test methods for apparatus, involving immunity to continuous
and transient, conducted and radiated electromagnetic disturbances, including
electrostatic discharge, which are the necessary electromagnetic compatibility
requirements.
This Part applies to audio, video, audio-visual and entertainment lighting control
apparatus for professional use as defined in Clause 3 and apparatus used in the
electromagnetic environment described in Clause 4, including the professional digital
apparatus defined in 3.5 and the components specified in 7.4.
This Part specifies that the disturbance signal frequency range is 0 Hz ~ 400 GHz, but
does not make the requirements for the entire frequency band.
Annex C provides relevant information on infrared emitters with wavelengths of 0.7 μm
to 1.6 μm.
This Part does not consider conditions of disturbance source or disturbed apparatus
failure.
The apparatus defined in 3.4, 3.5 and 3.6 may be operated in any form of power suppl......
