Functionality:
- detection analysis signals (dynamic electret) microphones in cables;
- activation electret by giving bias voltage their detection;
- detection transferring information on cables range 100 kHz - 180 MHz;
- detection unauthorized galvanic connections using NLJD REF;
- measurement AC DC cables.
