WinVNA

  • nanoVNA-H (original / basic model)
  • Other compatible VNAs with the same USB VID/PID (not fully tested)

Features

  • Control of compatible VNAs via USB serial (SV4401A, nanoVNA-H, ...)
  • Single and continuous frequency sweeps
  • Simultaneous display of S11 and S21 traces
  • Marker placement and tracking with readout of frequency and level
  • Smith Chart window for impedance visualization
  • Export of measurement data (CSV, S1P/S2P formats)
  • Customizable colors and display settings
  • Integrated command window and communication logfile
  • Built-in screenshot capture
  • Multi-language user interface (e.g. en-GB, es-ES)
