Non Linear Junction Detector - or an NLJD, is a device that illuminates a small region of space with high-frequency, RF energy. Any "non linear junction" in the vicinity—for example, and particularly, the p-n junction -- will receive this energy, and because of the non-linear nature of the junction, it will rectify it, re-emitting some of it on multiples of the illumination frequency (see harmonic). The detector has a sensitive receiver tuned for these harmonics, as well as appropriate processing and displays to make their presence known to the user of the device.
The non-linear junction detector ST-400 CAYMAN is designed for search and detection of hidden electronic devices installed in walls, floors, ceilings, fixtures, furniture, or containers, regardless of whether the electronic target is radiating, hard wired, or even turned off.
All modern electronic devices contain semi-conducting components. Using a non-linear junction detector it is possible to find these components
ST 400 CAYMAN NLJD may be used for:
• Searching for active and passive electronic eavesdropping devices;
• Detection of mobile phones and SIM cards;
• Checking parcels and mail for contraband or dangerous attachments containing semiconductors;
• Searching for other unauthorized electronic devices comprising semiconductor elements.
ST-401 "Cayman" - Non-linear junction detector
New! ST-401 "Cayman" - Non-linear junction detector
Non-linear junction detector ST401 series «CAYMAN» is a portable modification of the basic model NLJD ST-400.
Thus ST-401 retained all modes implemented in the basic model. The main difference from the basic model, is the lack of a telescopic rod and the use of small batteries. ST401 is especially useful when working in a confined space when checking small loads, mail, as well as screening people. ST 401 allows you to detect, turned on and turning off electronic devices, as well as pinpoint their placement. Using the detector, the operator can distinguish between "feedback" from the real semiconductors "false" signals (corrosion, metal structure, metal-oxide - metal).
The nonlinear transition detector lornets new 2012-0836-911is an indispensable tool for the rapid and reliable detection of devices containing semiconductor components. It can be used to combat surveillance job search on campus
The nonlinear transition detector lornets new 2012-0836-911is an indispensable tool for the rapid and reliable detection of devices containing semiconductor components. It can be used to combat surveillance job search espoused on the premises (concealed transmitter identification), as well as for placing explosive devices outside. DPF (double frequency sensing) technology with a patented antenna system places it actually different from the competition.
Lornety is a unique nonlinear transition detector that features compact size, ergonomic design and weight. These dimensions are as small as 39-10cm x 4, the weight is less than 700 g due to its thinest antenna (only 18mm) can be used for difficult to find places.
Lornety is highly competitive with most popular models of nonlinear area detectors.
It can work in continuous and pulse mode also with a performance variable.
