NEW! "Spider" ST-300 - wireline analyzer

wireline analyzer Spider-st-300 wireline analyzer Spider-st-300
Wireline and mains analyzer “Spider” ST-300 is designed to detect and locate eavesdropping devices, galvanically connected to power and low-current wire lines in the inspected object. The analyzer uses both passive and active modes of operations. This allows detecting eavesdropping devices which are in active or in stand-by mode at the time of a sweep operation.

 

 

 

Application
In ST-300 “Spider” there are set of functions implemented, which are most necessary for the detection and localization of wired eavesdropping devices. These functions include:
• Detection and evaluation of low-frequency signals in low-current conductive lines;
• Activation of electret cable microphones by filing an in-line bias voltage;
• Detection of eavesdropping devices signals, which are transmitting information via power and low-current lines in the frequency range from 100 kHz to 150 MHz;
• Detection and assessment of unauthorized galvanic connections to conductive lines using methods of non-linear junction detection and reflectometry;
• Tracking wire lines laid in walls and other building structures using trace locator.
 
Use of automated mode of analyzer, in combination with electronic switch, allows to carry out various kinds of measurements on all the possible combinations of pairs of multi-wire cable in a few seconds. Adapters, couplers and cables, which are included in the set of ST-300 SPIDER delivery set, allows to connect the device to the most common types of wired lines. The device can be used in standalone mode or controlled from a personal computer.
 
 
Modes of operation
The solution of different ways to detect wired eavesdropping devices is ensured by the multifunctionality of ST-300, appropriate accessory pack and the use of passive and active modes of operation.Systems technical and programming basis, implemented in the structure and unique algorithms allows to use it in the following modes:
• Electronic switch;
• Low frequency amplifier;
• Wireline receiver;
• nonlinear junction detector for wire lines;
• Reflectometer;
• Trace locator.
• Switching ST-300 in any of these modes is carried out compulsorily as at the same time the device can only operate in one of the main modes.
