Professional wideband portable bug detector

The SPECTRADOME CM55 is a very sensitive broadband RF detector with continuous coverage from 500Khz to 25Ghz: it allows the detection of virtually any transmitter on the market.
The operational functions are optimized for detection of professional RF sources, together with a circuit that also allows the detection of the intensity of the source signal and its consequent identification.

Many of the current radio transmitters used as bugs allow particular performances, with emissions usually not detectable before their activation. The only approach capable of preventing illegal listening is to electronically search for any unauthorized broadcasters, in addition to subsequent permanent protection over time.
The SPECTRADOME CM55 has been designed to allow electronic research of RF sources at a professional level, while at the same time providing a basic level of permanent protection over time even to users who do not possess any specific skills.

SPECTRADOME CM55 is light and compact, completely portable and complete with the following functions:
• high sensitivity and wide dynamic range
• extremely wide detection coverage (up to well 25GHz)
• short pulse detection for digital transmitters and storage of the peak level of the signal
• anti-interference filters
• demodulation of the detected / received audio carrier to eliminate false alarms
• Geiger-type audio carrier detection
• multimode indicator of the received signal strength (bar, numeric, delayed bar, peak)
• detection of all radio sources, including digitally coded ones)
• detection of spread-spectrum, frequency hopping and pulsed transmissions
• allows detection of transmitters inserted into modified cell phones and computers
• permanent protection thanks to the recording of search events (including time and signal level data)
• elimination of RF background noise
• calculation of power and distance from the RF source
• low current consumption
