The IEC 61000-4-3:2020 fourth edition applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy has been released. Updates include a description of how to test using multiple test signals, the addition of information regarding equipment under test and cable layout, the removal of the upper frequency limitation to take into account new services, and specification of how to characterize the uniform field area.
The adoption of multiple signal testing in IEC 61000-4-3 Edition 4 solidifies its credibility in electromagnetic compatibility (EMC) testing. The MT06002 Multi-Tone test system from AR RF/Microwave Instrumentation has 
Source: AR RF/Microwave Instrumentationestablished itself as the leader in multiple signal radiated and conducted immunity testing. With AR’s proprietary Multi-Tone software, users are offered numerous test and calibration routines utilizing multiple tone methodology to meet these standards.
By testing multiple frequencies (tones) at once, test times can be reduced by a factor equivalent to the number of tones selected. The MT06002 offers testing from 10 kHz to 6 GHz, with up to 1 GHz instantaneous bandwidth, greatly expanding an EMC laboratory’s opportunities beyond IEC 61000-4-3 to include conducted immunity and allows for more tones to be used during testing.
