Non-Linear Junction Detector

Non-Linear Junction Detector
Non-Linear Junction Detectors are used for the search and location of any semi-conductor element (diodes, transistors, circuits etc) including electronic (hidden) devices.  Semi-conductors contain multiple layers of silicon (P-Type and N-Type), and the point where they meet is called a Non-Linear Junction.  This junction also appears when dis-similar metals come into contact with each another.

The use of such detectors will accurately find from a safe distance potential eavesdropping devices by flooding the target area with a spectrally pure microwave RF signal.  Various frequencies are then monitored for a reflected 2D and 3D harmonic signal which enables a quick and reliable identification of such electronic devices and natural oxide semi-conductors.

This type of equipment will automatically find the best receiving channel frequency (free of noise and distortion) providing flawless operation even in the most demanding electromagnetic environment for example; identifying an object such as a SIM card from over one (1) meter away.
