LibreVNA 100kHz-6GHz USB Full 2-Port Vector Network Analyzer with External Reference

LibreVNA (TM) is a USB-powered, full 2-port vector network analyzer developed by Jankae that covers 100kHz-6GHz. Its architecture uses three ADCs sampling simultaneously and FPGA-based signal processing to deliver high-speed measurements — it can sweep over 10,000 points of full dual-port data in under 1 second. The instrument pairs a 16bit ADC and an ultra-low-noise power supply with a precision CNC aluminum, shielded enclosure to provide up to 100dB of effective dynamic range. Many performance characteristics approach those of lab-grade VNAs, but the project remains a work in progress. Some design elements are not finalized and overall performance can degrade when operating above 3GHz; please review these limitations before purchasing. The unit also supports an external reference. If you have ideas or feedback for future revisions, Jankae welcomes your input.
