Spider Wire Line Analyzer
There are set of functions implemented with the Spider 300, which are 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 a trace locator.
The use of the automated mode in combination with the electronic switch, allows the operator to carry out various kinds of measurements on all the possible combinations of pairs of multi-wire cable in seconds. Adapters, couplers and cables, which are included in the SPIDER 300 delivery set, allows connecting the device to the most common types of wired lines. The device can be used in a standalone mode or controlled from a personal computer.
Modes of operation
Providing different ways to detect wired eavesdropping devices is ensured by the multifunctionality of the Spider 300, appropriate accessory pack and the use of passive and active modes of operation. The systems technical and programming base, implemented in the structure and unique algorithms, provides the following modes:
- Electronic switch;
- Low frequency amplifier;
- Wireline receiver;
- Nonlinear junction detector for wire lines;
- Trace locator.
