Shielded measurements

The EM Lab offers state-of-the-art equipment and measurement capabilities for radiation and EMC tests.

Radiation pattern measurements of (active) antennas is possible in both RF and mmWave frequency bands. The NSI-700S-30 system, in combination with Agilent N5242A 4-port PNA-X Vector Network Analyser, VDI VNA-x range extenders, enables both near field (ideal for electrically large antennas) and far field measurements in a very wide frequency range: from 800MHz up to 170 GHz.

A Rohde and Schwarz FSV40 Spectrum Analyser with external 60 GHz mixer can be used for transmission measurements in our full anechoic chamber (dimensions of the shielded room: 8.1m x 3.9m x 3.6m), over a transmission length of 4 to 5m (quiet zone diameter 1m). Scientific Atlanta Standard Gain Horns (SGH) are used as transmitter antenna. For polarization measurements, the transmitting SGH is mounted on an Orbit/FR AL-360-1P Polarization Positioner placed on a TX Antenna Mast covered with radiation absorbing material (RAM). For 3D radiation pattern measurements, the antennas are mounted on the dielectric belt-driven rotator mast (AL-DBDR-3g), able to rotate a load up to 12kg along azimuth and roll.
