GENE-H-30-3K E/H Field Generator

The E/H field generator is specially designed for the immunity test to electromagnetic fields on medium-sized devices. It can also be used for specific tests according to the MIL-Standards. The main advantage of this line is that the equipment under test can easily be successively tested in both polarisations. The height of the structure can be adjusted to optimize the field intensity. The line is electrically symmetrical and the impedance is adapted through transformers on both sides. The parallel plate line can also be used for immunity tests on automotive devices according to the European directive 2004/104/EC or to ISO 11451-2 and on broadcast receivers and associated equipment according to EN 55020.It consists of a structure to be placed in the chamber or in an open area test site. The 2 slopes of the structure and the line are made with wires. The structure can be dismounted easily in order to carry out other tests in the chamber. Some precaution must be taken if the field generator is installed close to metallic structures in order to avoid resonances.
