The CORDON-4 is a broadband radio receiver intended for searching and locating low power sources of electromagnetic radiation in wide frequency range.
The analyzer allows not only detect radiation of secretly installed radio transmitter in the premises given, but also measure its signal frequency and assess power of electromagnetic radiation at the receiving end.
The CORDON-4 has three operating modes: field indicator mode, spectrum analyzer mode and identifiers mode. Field indicator mode is intended for identifying and locating low-power sources of electromagnetic radiation. Spectrum analyzer mode is intended for analyzing spectrum of detected signals. Identifiers mode is used to detect and identify wireless devices operating in 2.4GHz WiFi and Bluetooth standards.
The CORDON-4 makes it possible to identify devices of WiFi (2.4 GHz) and Bluetooth standards, while the operation of the devices of the remaining wireless communication standards can be observed in the corresponding frequency bands using built-in spectrum analyzer.
