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

Turn the S-A-A-2 off, then turn it back on while holding the right-hand button down. The screen should remain white, indicating it is in upload mode. Flash Firmware:

The S-A-A-2 uses a standard USB-CDC (Communications Device Class) interface. Windows 10/11 will automatically install the drivers.

: NanoVNA-QT is the primary method for flashing new firmware to the S-A-A-2 hardware. Setting Up the Connection

button while powering on the device (the screen will stay white), then select the device in the software to begin the flash. Data Export : Easily export your measurements to Touchstone (.s1p, .s2p) files for professional simulation software or for documentation. The Importance of Calibration NanoVNA V2 aka S-A-A-2 - EEVblog 22 Mar 2021 —

Tip: Save this calibration profile inside NanoVNA-QT ( Calibration > Save As ). Name it based on your frequency sweep (e.g., 2m_70cm_band.cal ) so you can reload it instantly without recalibrating every session. Key Measurement Applications

Allows you to mathematically "extend" the measurement plane to correct for cable length after a calibration is performed. Data Export: Export your results as or industry-standard Touchstone Turn the S-A-A-2 off, then turn it back

The paired with the S-A-A-2 (NanoVNA V2) vector network analyzer creates an incredibly powerful, laboratory-grade RF measurement ecosystem on a budget . While the S-A-A-2 hardware is a highly compact, standalone tool, its 2.8-inch screen makes fine tuning and complex data analysis challenging. Shifting your controls to a PC with NanoVNA-QT unlocks real-time high-speed sweeping, 1024-point data collection, and easy Touchstone (.s1p/.s2p) data exports for professional simulation programs.

Pro tip: If the device disconnects during sweeps, lower the sweep points to 201 or 301 points via the software settings. Windows 10/11 will automatically install the drivers

Note: The S-A-A-2 uses a slightly different USB-Serial chip than the original "H" version. Sometimes you need to ensure your USB drivers are up to date, but once connected, the serial link is stable.

The S-A-A-2 hardware was built for portability, but it has the heart of a bench instrument. NanoVNA-QT simply unlocks that potential. It stops being a gadget you carry in your pocket for field tests and becomes a permanent fixture on your workbench—essential gear for filter design, antenna tuning, and impedance matching.

This makes the S-A-A-2 + nanoVNA-qt combination a true automated test station for production or research.

: Attach the Male Open calibration standard to Port 1. Click Open in the software. Wait for the sweep indicator to finish.
