Choose the correct COM port (Windows) or serial device (macOS/Linux).

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)

Once all steps display a completion checkmark, click . Go to Calibration > Save As to save this calibration profile to your PC. This prevents you from needing to re-calibrate if you accidentally close the software. Analyzing Measurements and Traces nanovna-qt pc software with the s-a-a-2

Look for the latest releases on the GitHub repository for NanoVNA-QT/S-A-A-2. Step 2: Connecting the Hardware

The original NanoVNA (H/H4) operates up to 1.5 GHz. The is a different beast. It uses a different bridge architecture (the MS5351 and MS5525 ) allowing it to sweep up to 4.4 GHz (or 3 GHz for the V2.2).
