An RF Explorer Spectrum Analyzer is a special device designed to detect very sensitive signal radiation and identify signal interference, tune antenna setups, detect signal leakage and find hidden bugs, among many other applications.
The combination of small size, great sensitivity, and robust design makes it the ideal instrument to carry on for indoor and outdoor measurements.
When connected to a computer, it can be controlled by free software available for download with stunning high-resolution graphics, data storage, and reply features.
