    LibreVNA 100kHz-6GHz Vector Network Analyzer, SEESII Profesional NanoVNA Antenna Analyzer USB Based Full 2-Port with External Reference Input/Output,Measuring Full S-Parameters,2021 Upgraded Version

    • LibreVNA 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 LibreVNA Antenna Analyzer provides a 100kHz to 6GHz ultra-wide frequency range(previous vna analyzers are about 10KHz-1.5/3GHz),the Frequency Accuracy is <2ppm.
    • 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, please fully understand the possible limitations before buying this machine.
    • 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
