Pc Software With The S-a-a-2 — Nanovna-qt

Getting your S-A-A-2 (also known as the NanoVNA V2) running with NanoVNA-QT software is a great move—it gives you a much larger screen for viewing Smith charts and VSWR plots than the device's tiny built-in display.

21 Apr 2021 — None of the current PC software (NanoVNA-saver, NanoVNA-Sharp, TAPR, WebApp) work with the NanoVNA-V2. Rune has ordered a NanoVNA- NanoVNA V2 Vector Network Analyser - First Impressions nanovna-qt pc software with the s-a-a-2

Using NanoVNA‑Qt with the S-A-A‑2: A Practical Guide for Hobbyists

The NanoVNA family of vector network analyzers put powerful RF measurement tools into the hands of makers, ham radio operators, and RF tinkerers. Paired with NanoVNA‑Qt — a modern, actively developed desktop application — and an S‑A‑A‑2 antenna analyser adapter (SAA2) or similarly named serial adapter used to interface older NanoVNA hardware, you get a streamlined workflow for calibration, sweeping, and saving measurements for analysis and antenna tuning. This post walks through setup, practical tips, and common workflows so you can get accurate S11/SWR and impedance plots with minimal fuss. Getting your S-A-A-2 (also known as the NanoVNA

Configure NanoVNA‑Qt for the S‑A‑A‑2

  1. Open NanoVNA‑Qt.
  2. In the device connection dialog, select the detected serial port and the appropriate baud rate (commonly 115200 or 460800 depending on firmware). If using a V2 with native USB, the app may list it as a HID device.
  3. Choose the correct protocol/driver if prompted (some NanoVNA clones require selecting the “legacy” protocol).
  4. Click Connect. NanoVNA‑Qt should read the instrument info and display a live trace.

The software provides a secure method to update the S-A-A-2 firmware. Open NanoVNA‑Qt
