The analyzer is designed to detect and localize eavesdropping devices galvanically connected to power and low-current wire lines. ST 301 uses passive and active operating modes, which allow detecting working, switched off or faulty eavesdropping devices.
Description:
Functionally, the device consists of four detection channels.
Passive channels:
LOW-FREQUENCY AMPLIFIER WIRED RECEIVER Active channels:
NON-LINEAR LOCATOR REFLECTOMETER Only one channel can operate at a time.
Each CHANNEL operates in certain MODES.
Each MODE corresponds to a set of search FUNCTIONS.
Functional capabilities:
detection and analysis of signals from cable (dynamic and electret) microphones in low-current wire lines; activation of electret cable microphones by applying bias voltage to the line in order to detect them; detection of signals from eavesdropping devices transmitting information via power and low-current lines in the frequency range of 100 kHz - 180 MHz; detection of unauthorized galvanic connections to wire lines using the NON-LINEAR LOCATOR and REFLECTOMETER channels; measurement of direct and alternating voltage in the low-current line being tested.
