Seesii

$698.99

More Details
Main highlights
- Upgraded Professional LibreVNA: The LibreVNA Antenna Analyzer provides a 100kHz to 6GHz ultra-wide frequency range(previous vna analyzers are about 10KHz-1.5/3GHz),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
- 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
- Full S-Parameters Measurements: In Vector Network Analyzer operating mode, the LibreVNA can measure the complete S11, S21, S12 and S21 parameters. A source signal is generated and alternately applied to the RF ports. The incoming signal at both RF ports is measured, resulting in the four S-parameters S11 and S21 (when the source signal is routed to port 1) as well as S12 and S22 (when it is routed to port 2)
- Comparable to Lab-grade VNAs: 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.This 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
- 3-In-1 Function: Although the LibreVNA hardware is not designed to be used as a spectrum analyzer, the general hardware architecture of a spectrum analyzer is similar enough to that of a VNA to implement basic two-channel spectrum measurements and perform basic spectrum measurements output CW signals.Which might suffice if no other professional equipment is available.The main differences to a real spectrum analyzer and signal generator pls refer to the product Instruction
