LBX1650 RF TEST ENCLOSURE

LBX1650 shield box brings shielding, test access and connectivity together in a format that can be tailored to the application. Depending on the application, it can be specified with High Performance RF Absorber lining and Rugged Welded Construction. This approach keeps the enclosure practical for day-to-day engineering work while maintaining a controlled space around the device under test. It is well suited to controlled RF validation, development and production test workflows where repeatability matters. As a RF shielded enclosure, LBX16050 can be configured around the DUT and the way it needs to be tested.
