LibreVNA 100KHz~6GHz USB Based 2-port Vector Network Analyzer +LibreCAL Electronic Calibration KitsLibreVNA 100kHz - 6GHz USB based full 2-port vector network analyzer
LibreVNA (TM) is a USB based full 2-port vector network analyzer designed by Jankae. Using 3 ADCs to sample data simultaneously and using FPGAs for signal processing, it is capable of scanning over 10,000 points of full dual-port measurements in less than 1 second. The ultra-low noise power supply design and the use of 16bit ADC, together with the precision CNC's aluminum shielded housing, achieve up to 100dB of effective dynamics. Many aspects are already comparable to lab-grade VNAs, but this is still a work-in-progress project. Some design features may not be perfect, especially the performance will drop when the frequency is higher than 3GHz, please fully understand the possible limitations before buying this machine. If you have any suggestions for future releases, please feel free to contact us as well.

Note 1:Due to structural limitations, S12 isolation is 10dB worse than S21. Above 3GHz, the performance decreases with increasing frequency, and the port isolation is only 50dB at 6GHz. Below 1MHz, the performance decreases with decreasing frequency, and the effective dynamic decreases to 70dB at 100kHz.
Note 2:The use of higher accuracy calibrators allows for higher precision measurements.
Note 3:The output power may decrease when the frequency is lower than 1MHz or higher than 3GHz.
LibreVNAis a trademark that we have registered or are in the process of registering in several countries. If you are building a VNA based on an open source project, please avoid using this trademark.
LibreCAL is the electronic calibration part of the LibreVNA
Calibration can be quickly and easily called up directly in the LibreVNA-GUI, eliminating the need for tedious manual work with mechanical calibrators.
LibreCAL is open source hardware, we have published all the production files, you can also make your own, but you need a professional metrology calibration and VNA for calibration. The LibreCAL we sell has been calibrated with metrology grade calibrators, and the S11 directivity is better than 50dB within 3GHz and better than 40dB above 3GHz, which is better than some mechanical calibrators that cannot provide calibration parameters, but it is important to note that even after rigorous calibration. Due to leaks inside the electronic calibrator, the electronic calibration cannot be performed and can be manually added using the mechanical calibration if necessary. Since LibreCAL is specifically designed for LibreVNA, internally stored calibration parameters can currently only be recalled by LibreVNA, and LibreCAL cannot currently be used for other VNA calibrations.
Verify the orientation of the electronic calibrator with mechanical calibrators and add additional isolation calibrations.
