Haefely MSURGE Antenna for a Magnetic Impulse Field Test System

The Haefely MSURGE is used for EMC Tests requiring impulse Magnetic Fields. It is an accessory to either the PSURGE 4010, PSURGE4, PSURGE6 or the PLATFORM surge testers. It enables magnetic field testing up to 3000 A/m as required by IEC 61000-4-9. The support stand can also be used for tests in accordance with IEC 61000-4-8 and IEC 61000-4-10.

The Haefely MSURGE has a 1m x 1m square, single turn antenna. A current of 3600A is needed to feed the coil to produce a field of 3000A/m. Magnetic field strength is defined at the center of a coil with ±3 dB variation. Magnetic field is orthogonal to the coil plane. Coil dimensions define the maximum EUT size as being 0.6m x 0.6m x 0.5m. The MSURGE can be used for both vertical and horizontal plane testing, by simply rotating the coil antenna in its mounting on the (optional) stand.

In conjunction with other Haefely EMC Test products, magnetic field testing can be fully or partially automated. Any Surge generator can be used together with the MSURGE to provide semiautomatic testing from the instrument front panel. Voltages can be programmed which correspond to a magnetic field strength at the center of the coil antenna.
