S-A-A-2/V2 uses a similar user interface to NanoVNA, but uses a different technical architecture. S-A-A-2/NanoVNA V2 does not load initial calibration data at startup, and does not automatically insert calibration data after the user changes the frequency. Must recalibrate or call back calibration data after start up and frequency change. Please read the instruction manual carefully before use to avoid damage to the device.
