RF Explorer 4G COMBO+ is a powerful Spectrum Analyzer, covering the full range starting at 50 KHz up to 4 GHz with no gaps or limitations. A future firmware license feature will allow it to expand the range up to 5.1 GHz.

When compared to the standard 3G Combo model, the new SLIM design offers an outstanding robust enclosure with a strong metallic body and shiny varnished paint, additional frequency coverage, and power sensitivity, a more convenient USB connector on the side and larger internal battery capacity.

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.
