We would like to offer You Line and Main Analyzer ST-301 SPIDER, which is designed to detect and locate eavesdropping devices, galvanically connected to power and low-current wire lines in the inspected area. The analyzer uses both passive and active modes of operation. This allows detecting eavesdropping devices which are in active or in stand-by mode at the time of a sweep operation.

Features:
– Detection of 100 KHz…180 MHz signals in wireline
– Detection of abnormal connections
– Measurement of distances;
– Bias voltage function for wired microphone bug activation
– Wired Non-linear Junction Detector mode
– Fast operation using built in automated mode
– PC software for deeper target analysis
