dAV-TRX
The dAV-TRX system is used for the bidirectional optical transmission of audio signals (voice) during EMC tests (intercom). The transceiver is equipped with a built-in microphone and an integrated loudspeaker.
Fields of application are the acoustic monitoring of warning signals in vehicles, e.g. the engine speed, or the function of audio devices during EMI tests.
The system can also be used as an intercom while setting up the equipment in absorber lined chambers. The device can stay in the chamber during the tests.
Full duplex can be achieved by using headsets.
