A non-linear junction detector Lornet is designed to detect various kinds of electronic devices containing semiconductor elements, such as microphone amplifiers, audio-recording, eavesdropping and other remotely controlled devices; both in switched-on and switched-off modes.

Characteristics:

  • Type of a probing signal: pulse, CW
  • Power of pulse/CW signal: 15/1 W
  • Sensitivity (by the 2nd and 3rd harmonics): not worse -120 dBm
  • Probing signal frequency: 880 - 906 MHz
  • Dynamic range: more than 80 dB
  • Operation time from a built-in battery at maximum power of probing signal (pulse/CW): not less 3.5 / 1.5 h
  • Dimensions in transportation /operation position: 57х22х12/100х15х4 cm
  • Full weight of the device in operation state: less than 1000 g

Application:

A non-linear junction detector Lornet is used for conducting a strategic and search work afield, in premises, transport, and is designed to find specific equipment containing semiconductor components. An automatic system of frequency selection is integrated into the device, and it can tune away from narrowband interference automatically (by a сriterion of minimum noise of the receiving channel of the 2nd harmonic).

Main Competitive Advantages:

  • Small dimensions and weight of the device
  • Easy-to-use, it is possible to use the device as checking one
  • Automatic and manual modes of power change of the probing signal
  • Use of the latest technologies and materials, ergonomic
  • High detection potential (it is highly competitive to the best samples)
  • Use of wireless earphones
  • It is possible to operate in hard-to-reach places and under conditions of limited space (antenna thickness does not exceed 18 mm).
