LibreCAL/LibreVNA 6GHz USB Vector Network Analyzer 100kHz …, Perth

LibreCAL Introduction 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 LibreCAL Description LibreCAL is the electronic calibration part of the LibreVNA Calibrator can be quickly and easily called up directly in the LibreVNA GUI eliminating the need for tedious manual work with mechanical calibrators LibreVNA Specifications Impedance 50ΩTest Port Connector SMA femaleNumber of Test Ports 2Frequency Range 100kHz to 6GHzFrequency Accuracy ≤2ppmNumber of Measurement Points 2 to 4501Speed 2 port 4000 points 10Hz to 50kHzDynamic R
