PKI 4305 can be used to locate eavesdropping devices which are galvanically connected to the object under investigation with current and low current wire lines. This is not possible with conventional HF detection devices. The various operating modes, such as LF amplifier, reflector network, receiver and detector for non-linear transitions, enable detection and analysis. Adapters, couplers and cables are supplied to perform the various types of measurements and all possible combinations of pairs of multicore cables. This allows fast detection with PKI 4305.
