The 4933 RF Shield supports radiation and quality measurements for large radio transceivers, notebook PCs, and other electronic equipment. It combines a high shielding factor with easy access to the UUT. The 4933 attenuates signals from either outside or inside by a high degree. The attenuation, in conjunction with the RF connector, can be used to measure the radiation of the UUT in an EMC prequalification test without the need for a large anechoic shielded chamber. The shield comes with a solenoid lock and a control panel displaying the status of the lock and a USB interface.
