Attention:clients from EU countries will be charged with VAT cost&service cost by the local express when doing custom clearance from July 1st, 2021. Pls be noted.LibreVNA 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.
