=> planning of shielding
=> testing of shielding

The PFD-3 is in form and function a progressive high frequency measurement system with a logarithmic periodical wide band antenna for measuring radiation density in the frequency range 250 MHz to over 2,5 GHz, according to used antenna. The extremely high sensitivity of the instrument makes it possible to measure C, D- and E-band network emissions easily even inside buildings. Also microwave ovens can be tested. The PFD-3 is one of the most sensitive measuring systems for non ionising radiation on the market. The measuring accuracy is good. In the frequency range from 500 MHz to 2 GHz mostly better than ± 3dB. Through the good direction sensitivity of the included antenna, the determination of the direction of RF fields is easy. Also the polarisation plain can be determined.
