  • Product Description
  • Technical Specifications

TECHNOLOGY:

The generation of microwave signals in the Non Linear Junction Detector, when in contact with transistors, diodes or chips re-emits certain higher frequencies, the re-emitted signal is received on the antenna and processed showing the 2nd and 3rd harmonics on LED indicators & earphones. This detectector detects a high amount of high level threats, such as listening devices.

20K MODE Allows for listening of low frequency devices such as tape recorders, radio, microphone amplifiers, and is a powerful tool in the identification of the type of non linear device (bug).


RESOLUTION:

The resolution of each LED indicator is 3dB and the received signal can also be heard with the accompanying earphones.
FREQUENCY TUNING Selects the best frequencies (not interfering with GSM range) allowing the unit to work in a concentrated environment.

ADJUSTABLE:

The Non Linear Junction Detector's emitting power can be adjusted as well as the receivers sensitivity.

CAPABILITY:

The Non-Linear Junction Detector operates in pulse mode with a power of emitter up-to 4 watts per pulse, this allows for higher (-120 dBm / -150 dB/W) sensitivity of the receivers. This is achieved by optimising the parameters of the signal in conjunction with a superior antenna system.

UNIQUE DESIGN:

Ergonomic one piece construction and light (1.3 kg including battery) with extendable/retractable poll inside the handle, as well the Non-Linear Junction Detector's innovative screw-in battery extends the handle further.

USAGE PARAMETERS:

Operation speed, product safety, ergonomics, battery and continuous usage time (not less than 5 hours), the Non-Linear Junction Detector exceeds all currently available Non Linear Junction Detectors.
