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
