RF Explorer RFEM4G PLUS is an expansion module to convert an RF Explorer WSUB1G PLUS into a powerful 4G Combo PLUS Spectrum Analyzer, covering the full range starting at 50KHz up to 4GHz with no gaps or limitations. A future firmware license will allow you to expand the range up to 5.1GHz with no need for additional hardware.

What is an RF Explorer Spectrum Analyzer?

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.
