LibreVNA 100kHz-6GHz USB Full 2-Port 2CH Vector Network Analyzer CNC Housing

Q: Hello, We are planning to use LibreVNA for an industrial microwave moisture measurement PoC. Could you please confirm: - This is a full 2-port LibreVNA - Frequency range is 100 kHz to 6 GHz - S11 and S21 magnitude/phase data can be measured - Remote/programmatic control is possible from our own software - Calibration kit is included or available separately Best regards

Hello, Yes, this is the full 2-port LibreVNA model with CNC housing. To confirm: Frequency range: 100 kHz to 6 GHz Measurements: S11 and S21 magnitude/phase data are supported, along with full 2-port VNA measurements Remote/programmatic control: Yes, LibreVNA can be controlled from software. It is suitable for automated or custom measurement setups, depending on your integration requirements Calibration kit: The calibration kit is not included by default unless specifically listed in the package contents. It is available separately and we recommend using a proper calibration kit for accurate S11/S21 measurements, especially for PoC or industrial testing For your microwave moisture measurement PoC, LibreVNA should be suitable for measuring changes in transmission/reflection characteristics, provided that your fixture, antennas/waveguides, and calibration setup are designed correctly for the target frequency range.

Description

The LibreVNA is a cutting-edge USB-based 2-port vector network analyzer designed for precision RF measurements from 100kHz to 6GHz. Featuring simultaneous dual-port sampling via 3 ADCs and FPGA processing, it captures 10,000+ measurement points in under 1 second. Encased in CNC-machined aluminum shielding, it achieves lab-grade performance with ultra-low noise and up to 95dB dynamic range below 3GHz.

Breakthrough Performance

Ultra-Fast Scanning: 4000 points in <500ms (IFBW=50kHz)
High Dynamic Range:
Precision Engineering: 16-bit ADC + low-noise power supply
Full 2-Port Measurements: S11, S21, S12, S22 parameters
Multi-Platform Support: Windows, Linux, macOS (64-bit)

Technical Specifications

Frequency Range: 100kHz–6GHz (±2ppm accuracy)
Test Ports: 2× SMA female (50Ω impedance)
Measurement Points: 2–4501 configurable
Output Power: -40dBm to 0dBm (adjustable)
Reference I/O: 10MHz external input/output
Power: 5V/1.5A via USB-C or 3.5mm jack
Additional Features: Spectrum analyzer mode, signal generator

Important Notes

Performance degrades above 3GHz: Isolation drops to 50dB at 6GHz
Reduced dynamic range at extremes: 70dB @ 100kHz
S12 isolation is 10dB worse than S21 above 3GHz
Output power decreases below 1MHz and above 3GHz

Purchased 2 units for my firm. We used it to design a couple of 2.4Ghz antennas. Its a great product considering its price and capabilities. The software was also easy to use.

Advantages

Great support, they provided us with fast responses to all of our questions and provided support along the way.
