The WG S RF Detector can be used to detect and locate a wide variety of radio transmitters used for covert access to audio and video information .
Its scanning and analysing cycle period is 1.0 – 1.5 sec, operating in monitoring, sweep, and search modes for digital signals.
The filtration of short term noise requires at least two scanning cycles, so the signal is detected in 2-3 seconds.
Soundless alarm indication in vibration mode and the absence of external antenna helps the device to attract little attention.
Its detector is a super heterodyne receiver with low IF and frequency synthesiser, providing continuous scanning of frequency range and analysis of spectrogram peaks.
Standard digital signals are identified by their amplitude-time characteristic.
Any continuous radio signal with the amplitude modulation index ≤0.5 without frequency hopping is treated as an analog signal.
It will detect analog signals AM, FM, PM modulation and digital signals of FSK, PSK and similar modulations.
