dAV-TRX
The dAV-TRX system is used for the bidirectional optical transmission of voices during EMC tests (half duplex intercom). One transceiver is equipped with built-in batteries for mobile use (inside ALC), the second one is powered with an external power supply. Fileds of application are the acoustic (and optional optical) monitoring of A/V – devices, engines or radios and the use as an intercom system for absorber lined chambers. The device can stay in the chamber during the tests.
