Description:
We maintain close cooperation with developers and now launch the long-awaited USB-based full dual-port vector network analyzer LibreVNA up to 6GHz for radio enthusiasts and geeks. LibreVNA uses 3pcs ADC for data sampling at the same time, and uses FPGA for signal processing. It can scan more than 10,000 full dual-port measurements within 1 second, and obtain complete dual-port S parameters (S11, S21, S22, S12). Ultra-low noise power supply design and the use of 16-bit ADC, coupled with precision CNC aluminum shielding shell, s21 achieves an effective dynamic up to 100dB. In many respects, it is comparable to laboratory-grade VNA, but this is still an ongoing project. Some design features may not be perfect, especially when the frequency is higher than 3GHz, the performance will be reduced, please fully understand the possible restrictions before buying this machine.

Specifications:
* Impedance: 50Ω
* Test Port Connector: SMA, female

* Supported Operating System: For Windows, Linux, MacOS (Only 64-bit software is available for now)
* External Reference Input: SMA female; 10 MHz
* External Reference Output: SMA female; 10 MHz or 100MHz. Simple spectrum analyzer (Lack of mirror suppression and slower speed)
* Further measurement options: Signal generator (Not precisely calibrated)

Note 1: Due to structural limitations, the isolation of S12 is 10dB or more worse than S21. Above 3GHz, the performance decreases as the frequency increases, and the port isolation is only 50dB at 6GHz. Below 1MHz, the performance decreases as the frequency decreases, and the effective dynamic decreases to 70dB at 100kHz.
Note 2: If you have a higher-precision calibrator that can achieve higher measurement accuracy, we can also provide you with higher-precision calibration parts, but the price of high-precision calibration parts far exceeds the price of LibreVNA.
Note 3: When the frequency is lower than 1MHz or higher than 3GHz, the output power may decrease.
