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

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
