1AURSINCAURSINC LibreVNA 2.0 Vector Network Analyzer, 100KHz-6GHz Professional Antenna Analyzer Measuring Full S Parameters with External Reference Input/Output, USB Based Full 2-Port Interface
9.6 Precision9.1 Interactive Display8.6 Simple to useMain highlights- [Upgraded Professional LibreVNA] LibreVNA is a open-source hardware, USB based full 2-port vector network analyzer (VNA) designed by Jankae, provides a 100kHz to 6GHz ultra-wide frequency range. Updated 6-layer PCB design that optimizes S12 port isolation and high-frequency port matching. Supports firmware update and can load a new microcontroller firmware and FPGA configuration into the LibreVNA
- [Packing List] 1x LibreVNA host, 1x USB type-C data cable, 1x USB power cable, 2x 30cm SMA male to male SS405 RF cable, 1x SMA male calibration kit - OPEN, 1x SMA male calibration kit - SHORT, 2x SMA male calibration kit - LOAD, 2x SMA female to female connector, 2x SMA male to male connector, 1x English manual. The LibreVNA is highly functional and capable of meeting the demands of RF engineers, researchers, or hobbyists for a wide range of RF measurements and microwave network parameter measurements
- [PC Software Control] The LibreVNA needs to be used with the host computer software and a separate screen, as it does not have a built-in monitor. LibreVNA provides software for the Windows and Ubuntu platforms. You just need to download and unzip it to run. Supported Operating System: Windows, Linux, MacOS. (Only 64-bit software is available for now)
- [Full S-Parameters Measurements] In the LibreVNA operating mode, the VNA can measure the complete S11, S21, S12 and S21 parameters. A source signal is generated and alternately applied to the RF ports. This incoming signal at both RF ports is measured, resulting in the four S-parameters S11 and S21(when signal routes to Port 1), as well as S12 and S22(when signal routes to Port 2)
- [Frequency range] Supports a wide range of frequency measurements from 100kHz to 6GHz, upgraded Frequency Accuracy is <2ppm. The S12 can achieve over 90dB of port isolation below 3GHz, allowing measurements above 6GHz use harmonics. During up to 9GHz actual tests, both S11 and S22 have more than 10dB port directivity, and S12, S21 have more than 40dB dynamics
- [Comparable to Lab-grade Nano VNA] 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. Using 3 ADCs to sample data simultaneously and using FPGAs for signal processing, Libre VNA handheld antenna Analyzer is capable of scanning over 10,000 points of full dual-port measurements in less than 1 second
- [3 In 1 Device] Although the VNA hardware is not designed to be used as spectrum analyzer and signal generator, the general hardware architecture of a spectrum analyzer and signal generator are similar enough to that of a VNA to implement basic spectrum measurements and output a CW signal, which might suffice if no other equipment is available. The main differences to a real spectrum analyzer and signal generator please refer to the product manual
