What is a Spectrum Analyzer

A LATNEX Spectrum Analyzer is a specialized device that can detect highly sensitive signal radiation, identify signal interference, optimize antenna settings, detect signal leakage, and locate hidden bugs, among other capabilities. The combination of small size, high sensitivity, and rugged design makes it the ideal instrument for indoor and outdoor measurements. When linked to a computer, it may be controlled by a free software that includes high-resolution images, data storage, and reply features.

When linked to a PC, the LATNEX SPA-7GE provides enhanced capabilities. Its multi-platform software, along with its API libraries, is open-source and supports Windows, Linux, and MacOS X operating systems. This ensures flexibility and accessibility across different platforms. The software is available for free download.
