- Category:- Measuring equipment,All products,Drone/drone system,Tools, measuring equipment
LibreVNA is a USB vector network analyzer with two ports and is open source. The device serves as an RF interface with some computing power, while the main processing is performed by software on a PC. LibreVNA is capable of performing 10,000 dual-port point measurements per second and has an effective dynamic range of 100dB. The analyzer board is equipped with three ADCs and an FPGA for signal processing.
With two measurement ports, the analyzer can measure the full set of reflection and transmission coefficients (S11/S12/S21/S22). Although the LibreVNA hardware is designed as a vector network analyzer, its architecture is so similar to that of a spectrum analyzer that it can also perform basic dual-channel spectrum measurements.
Key features
- Covers a wide frequency range from 100kHz to 6GHz, allowing measurements at different frequencies
- Measurement of SWR (VSWR) of antennas, smear diagram
- Equipped with two test ports, allowing you to measure a full set of reflection and transmission coefficients (S11, S21, S12, S22)
- Capable of performing up to 10,000 dual-port point measurements per second
- Has an effective dynamic range of more than 95dB for frequencies up to 3GHz and more than 50dB for frequencies up to 6GHz
- Built-in 3 analog-to-digital converters (ADCs) and a programmable logic gate array (FPGA)
- Has an open source code

Notes:
Since the LibreVNA analyzer is open source, there are some design limitations:
- Due to some structural limitations, the isolation of S12 is 10dB worse than that of S21
- Above 3GHz, the performance decreases with increasing frequency, resulting in a port isolation of only 50dB at 6GHz
- Below 1MHz, performance decreases with frequency, and effective dynamic range is reduced to 70dB at 100kHz
- Output power may decrease if the frequency is below 1MHz or above 3GHz
With this LibreVNA, the use of more accurate calibrators ensures higher measurement accuracy.
