QM-4000

QM-4000 is an advanced network system for complex protection of an object against eavesdropping. The system allows parallel connection of up to 32 MRA-3Q radio analyzers using a dedicated object network. QM-4000 allows full remote control of each device, and supports numerous additional features like spectrum analysis in the range of 36-3600MHz, background statistic, new signal statistic, automatic audio sampling, frequency and spectrum records, selective statistic, system statistic, etc. All these features are easily accessible from the QMaster software - a user friendly control application with ergonomical graphical user interface. QM-4000 is not only a comprehensive solution for object permanent protection, but also a very effective tool for electronic countermeasures specialists since it gives a clear graphical picture of the current RF signals. QM-4000 allows to detect and record even such dangerous systems like spread spectrum, or modified WiFi, DECT, and GSM.

The MRA-3Q is an advanced automatic radio scanner suited for instant detection of various types of radio bugs in the frequency range 36-3600 MHz. The basis of the system is the radio spectrum memory combined with an ultrafast scanning. The whole frequency range is scanned every eight seconds and the currently received signals are compared with the initially stored "clean" background spectrum. The presence of a new signal activates a three level alarm output and time & frequency information are stored in the new signal memory. Although the MRA-3Q alone is a very effective protection tool against RF eavesdropping when connected to the QM-4000 object network controlled by the QMaster software its efficiency and functionality is greatly extended.
