Near-field Chambers
Most antenna measurements need to be carried out in the far field; that is, the test antenna should be illuminated by a plane wave. Typically this is carried out by providing sufficient separation between the source and the AUT so the spherical wave approaches a plane-wave character.

Near Field Probes
A typical emi emission test is performed using broadband EMC antennas such as biconical, log periodics, Combilogs and horns. These antennas usually placed at 1, 3 or 10 meter distance as required by the test specification. These is considered far field measurements and the emission limits are given for the specific distance by the specification. During EMI compliance measurements, the emissions levels from products are compared with these limits. If the product exceeds these limits it is considered failing. These tests are typically conducted in a open area test site IOATS) or inside an anechoic chamber.

Near Field Probe Set
RF100
The RF100 probe set consists of a passive E field probe and H field probe, BNC adaptor and carry case. The output is via a BNC socket. These are general purpose probes which are ideal for use in conjunction with an EMC measuring system. They are sensitive to sources in close proximity, but are insensitive to background signals. This makes them ideal for the identification of emission frequencies in noisy environments... thus making measurements easier and quicker. The proximity requirement also enables sources to be located and the exit route identified.
