Souderton, PA — October 21, 2020 — The new IEC 61000-4-3:2020 4th edition includes the following updates: a description of how to test using multiple test signals; the addition of information regarding EUT and cable layout; the removal of the upper-frequency limitation to take into account new services; and the further specification of how to characterize the uniform field area, as well as added clarification for checking the power amplifier linearity in the field generation chain.
The adoption of multiple signal testing in IEC 61000-4-3 Edition 4 solidifies its credibility in EMC testing. AR’s Multi-Tone test system, MT06002, has established itself as the leader in multiple signals 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. This mature software, as with AR’s emcware, has a very intuitive workflow and wide range of features, translating into true time savings for the lab. The MT06002 offers testing from 10 kHz – 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 allowing for more tones to be used during testing.
