SAA-2N NanoVNA V2.2

3GHz vector network analyzer, designed by OwOComm, under the LGPL license agreement, it is completely manufactured according to the v2_2 files issued by OwOComm at https://github.com/nanovna/S-A-A Development Department, in line with the original technical specifications designed by OwOComm.

The SAA-2N/NanoVNA_V2.2 uses a similar user interface to the NanoVNA, but with a different technical architecture, the SAA-2N/NanoVNA_V2.2 does not load the initial calibration data at startup, and does not automatically interpolate the calibration data after the user changes the frequency, and must recalibrate or call back the calibration data after each startup and frequency change. Please read the user manual carefully before use to avoid damaging the device.

User guide: https://github.com/nanovna/NanoVNA-QT/raw/master/ug1101.pdf



Because SAA-2 is an open source design, there are many different manufacturers. Some customers may have doubts about the performance of our products. The following is the touchstone file obtained by scanning different attenuators with NanoVNA saver. You can see the approximate effective dynamics and accuracy, as well as the accuracy of the calibrators we use. The following test results only represent the sample test data of our SAA-2 with metal shell items, and are not responsible for similar products sold through other channels.

The phases can also basically overlap:





Scanning the 6dB and 10dB attenuators on CH0 respectively, we can see that the return loss of 10dB attenuator is between - 20dB and-22db. The calibration accuracy and SAA-2 directivity are both very good.






Scanning 10 dB, 30 dB, 50 dB, 60 dB, 70 dB attenuators between CH0 and ch1, S21 up to 3.3 GHz can obtain satisfactory results.




Nanovna saver software now supports SAA-2.




VNA-QT software comes from the classic XaVNA.
