Product details
Wire analyzerST-301“ Spider”Intended to detect and locate listening devices that are electrically connected to electrical and low current wires in the inspected object. The analyzer operates in both passive and active modes. This allows detection of listening devices that are in active or standby mode during scanning operations.
Operation mode
•Low frequency amplifier.
•Wired receiver.
•Wired nonlinear junction detector.
•Reflectometer.
Functional Features:
•Detecting and analyzing signals from cables (dynamic and polarizable) microphones in low current wires;
•By applying onlineBIASVoltage is used to activate the electret cable microphone for detection
•Detect signals from listening devices, which are transmitted through power and low current lines100 kHz ... 180 MHzTransmitting information within the frequency range;
•Detecting and evaluating unauthorized current connections with wires using nonlinear node detectors and reflectometers;
•Measure the DC voltage and AC voltage in the tested circuit.
This analyzer has an integrated electronic switch designed to improve the efficiency of multi wire cable testing.
The automatic and manual modes controlled by the electronic commutator allow for the connection of all combinations of tested multi wire cable pairs, which are connected to the input connectors of the switch. The automatic operation mode and electronic commutator allow for various types of measurements to be performed in all combinations of multi wire cable pairs for a few seconds. The adapters, switches, and cables included in the kit can connect the device to common types of wires.
The automatic mode of the analyzer, combined with electronic switches, can perform various measurements on all possible combinations of multi-core cable pairs within seconds.ST-301 SPIDERThe adapters, couplers, and cables included in the delivery kit can connect the device to common wired lines.
