NanoVNA-QT (also known as VNA View) is the native PC software designed specifically for the (NanoVNA V2) series
With your calibrated setup, connect an antenna to Port 1. Look at the SWR trace. The lowest dip in the curve represents the point of best impedance match. By placing a marker at that dip, NanoVNA-QT will display the exact SWR, resistance, and capacitance/inductance. If the dip is lower than your target frequency, the antenna elements are too short; if it is higher, they are too long. 2. Measuring a Bandpass Filter (S11 & S21) : Obtain the latest release from the official
Seamlessly measure S11 (reflection) and S21 (transmission) across the S-A-A-2’s full frequency range, with automatic calibration data management.
Unlike other community tools, NanoVNA-QT is the native software for the V2 and later series. Key advantages include: Click Apply or Done
Windows 10 and 11 usually recognize the S-A-A-2 automatically as a Virtual COM Port (Cypress CDC VCP driver). If your PC fails to see the device, download and install the standard LibUSB or Cypress driver packages recommended by the NanoVNA design team. 3. Connecting the Hardware Power on your NanoVNA S-A-A-2.
Select and enter your lowest frequency (e.g., 140 MHz).
Advanced impedance and matching visualization, directly updated from the SAA-2’s raw data.
NanoVNA-QT allows you to open multiple windows or traces to analyze both S11 (reflection) and S21 (transmission) parameters.
