RF Analyzer

RF Spectrum Analysis with RF Explorer

RF Analyzer is a free, web-based app that turns data collected from RF Explorer spectrum analyzers into highly graphical charts and displays, enabling users to more readily visualize the RF environment, monitor RF signals, troubleshoot RF issues, and detect sources of RF interference.

In addition to running as a standalone, handheld device, RF Explorer can be connected to a PC where software is used to provide enhanced functionality and data analysis. The connection is made using a mini USB cable. (NOTE: A high quality USB cable should be used in order to limit EMC interference from the PC that could influence your measurements.)

RF Analyzer uses Web Serial technology that enables web browsers to communicate directly with serial devices via USB, bypassing the need for separate desktop software. And, more importantly, this allows RF Analyzer to be used on multiple operating systems (e.g. Windows, MacOS, Linux, Android). Web Serial technology is currently supported on Chromium-based browsers, such as Google Chrome, Microsoft Edge and Opera.

RF Analyzer is easy to use – simply attach your RF Explorer device to your desktop or laptop machine via USB cable (or mobile Android device via OTG cable) and you are ready to go. Scroll down to press the ‘Connect’ button and you can then begin scanning. There are 4 charts: RF Spectrum Trace, RF Spectrum Bars, RF Spectrum Bubbles and RF Spectrum Heatmap. You can also import / export spectrum traces in CSV format.

Troubleshooting Tips

  • RF Explorer devices require high-quality USB cables to ensure stable connections, proper charging, and to minimize Electro-Magnetic Compatibility (EMC) interference from PCs, which can corrupt measurement data. Using low-quality cables often leads to, or is mistaken for, driver issues.
  • Ensure the baud rate on the device is set to 500 Kbps (and not 2400 bps).
