The Analyzer is designed to detect and localize eavesdropping devices that are galvanically connected to power mains and low-current cables.
In the ST 301, passive and active modes of operation are used to detect enabled, switched off, or faulty eavesdropping devices.
Application
Functionally the Analyzer consists of four components (DEVICES):
1. LOW FREQUENCY AMPLIFIER (LFA)
2. WIRE RECEIVER (WR)
3. NON-LINEAR JUNCTION DETECTOR (NLJD)
4. REFLECTOMETER (REF)

23. Case
Functionality:
- detection and the analysis of signals cable (dynamic and electret) microphones in low-current cables;
- activation of electret cable microphones by giving to the cable of bias voltage for their detection;
- detection of signals of the eavesdropping devices transferring information on power mains and low-current cables in frequency range of 100 kHz - 180 MHz;
- detection of unauthorized galvanic connections to the cables using a NLJD and the REF;
- measurement of AC and DC voltage in the low-current cables.
