The NanoFarfield is a portable far-field measurement system for low-cost vector network analyzers like the NanoVNA and LiteVNA. It features a motorized rotation platform, amplifier, RF limiter, and measurement software to produce accurate radiation patterns and gain measurements. It's designed to be affordable, reproducible, and accessible for RF engineers, researchers, and makers.
GUI application for using HackRF as a spectrum analyzer with features like optimized settings, easy retuning, peak/persistent display, and more.
Here%u2019s a well documented RF spectrum analyzer project by Simpleavr. It uses the MSP430 TI Launchpad and the inexpensive RFM12B module to analyze signals in the 915 MHz band. The output is visualized on an attached Linux box running a Perl script.
