Non linear junction detectors NLJD-01 Non linear junction detector Non Linear Junction Detector represents a unique equipment capable to find out practically all concealed eavesdropping devices though the analysis of harmonic emissions caused by an illuminating signal when it is reflected off of a target. SPECIFICATIONS Power supply - Accumulator (7,2 V) Continuous operation time - Not less than 4 h. The transmitter operates in a pulse mode in a frequency range 915 MHz Spacing of retuning 200 KHz> Maximum impulse output power 16 V±1 Db Minimal impulse output power 1,6 Db Receivers adjustment frequencies are equal to double or triple transmitter frequency accordingly. Both receivers sensitivity at signal/noise ratio not less than 6 Db -136 Db/W Receiver dynamic range not less than 30 Db Manual receivers amplification control in 4 steps; each step equals to (10±1) Db In a "20K" mode of operation both receivers emits signals modulating radio-frequencypulse pattern. Demodulated signal bandwidth 500-2000 Hz. There are three aerials combined in one unit. Beam Width Angle (at 3 Db level on transmitting and receiving aerials) not more than 90. All aerials are circular polarized.
