The 5230 from ETS-Lindgren is a tabletop RF Test enclosure designed for conducting sensitive DUT measurements requiring shielding, such as mobile phones, including R&D, 5G, and Bluetooth testing. It has a welded construction and includes a large, unobstructed interior and zero perimeter doors with easy open/close progressive RF gasket compression mechanisms. This RF enclosure provides RF isolation of up to 120 dB at frequencies above 10 Hz. It has a magnetic field of 44 - 120 dB at 1 KHz - 30 MHz, an electric field of 120 dB from 1 KHz to 30 MHz, a plane wave of 120 dB at 30 MHz to 1 GHz and a microwave of 120 dB at 1 GHz to 10 GHz This standard configured enclosure offers an expedited lead-time, RF anechoic lining (absorber or ferrite tile), RF waveguide vents for cooling, and removable feed through panels for power and signal lines.
