The Telephone and line analyzer ST-301 Spider has been designed to detect and locate wiretapping devices galvanically connected to wired installations — low voltage and supplying power, for example in buildings. The device uses active and passive methods of operation enabling the detection of devices working during the check, and those in sleep mode by forcing their activation.
The Telephone and line analyzer ST-301 Spider is a refreshed version of the ST-300">ST-300, model with increased frequency range, sensitivity and response time. A series of technical solutions that are necessary in the detection and location of all wiretapping and anomalies occurring on installations in the facility.
The ST-301 telephone and line analyzer has an integrated electronic switch that aims to increase the performance of the multi-core cables tested. Automatic and manual electronic control modes allow connection of all combinations of pairs of wires of the tested multi-core cable that connects to the input connector of the switch. Adapters, switches and cables included in the set allow you to connect the device to the most popular types of cables.
Technical and software functions implemented in the ST-301 telephone and line analyzer and unique algorithms allow the use of many diagnostic tools in one device:
