2023 Upgraded LibreVNA 2.0 100kHz-6GHz Vector Network Analyzer,SEESII NanoVNA Antenna Analyzer USB Based Full 2-Port with External Reference Input/Output,6-Layer PCB Design Measure Full S-Parameters
★【Powerful Function & Firmware Update】: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.Support Firmware Update,can load a new microcontroller firmware and FPGA configuration into the LibreVNA. Do not disconnect power while updating the firmware!
This is an upgraded version of LibreVNA 2.0, New 6-layer PCB design optimizes the S12 port isolation and high-frequency port matching. The S12 can achieve over 90dB of port isolation below 3GHz, allowing measurements above 6GHz using harmonics. In actual tests up to 9GHz, both S11 and S22 have more than 10dB port directivity, and S12 S21 have more than 40dB 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, please fully understand the possible limitations before buying this machine.
The Librevna 2.0 vector network analyzer will be a nice addition device to the workbench, which is a very fully functional analyzer for electronics engineer, amateur radio operators or radio diy enthusiast.
