dAV-TRX-DSP
The dAV-TRX-DSP system is used for the bidirectional optical transmission of voices and other audio signals during EMC tests (half duplex intercom).
The integrated digital signal processor (= DSP) and the FPGA allow voice/sound activated half duplex comunication (in additon to "push to talk")
One transceiver is equipped with built-in batteries for mobile use (inside ALC), the second one is powered with an external power supply.
Fields of application are the acoustic monitoring of audio devices, engines or radios and the use as an hands free intercom system for absorber lined chambers. The mobile device can stay in the chamber during the tests.
