NanoVNA V2 / SAA2 3G Version VNA HF VHF UHF Vector Analyzer Network Antenna Analyzer with EVA Storage Bag

The SAA-2, designed by OwOComm, is a portable vector network analyzer up to 3GHz. We strictly follow OwOComm's documentation and use 0.5ppm TCXO to ensure high frequency measurement frequency accuracy. The complete metal casing can fully protect the internal precision circuit, and fully consider the protection of the external interface. Customized high performance SS405 cable provides good stability phase stability performance, high performance calibration kit ensures calibrated SWR less than 1.03 up to 3GHz.

SAA-2/NanoVNA V2 does not load initial calibration data at startup, nor does it automatically insert calibration data after the user changes the frequency. After the second start and frequency change, the calibration data must be re-calibrated or recalled. Please read the instruction manual carefully before use to avoid damage to the device. nanovna-saver: https://github.com/NanoVNA-Saver/nanovna-saver/releases VNA-QT software download: https://github.com/mdkendall/NanoVNA-QT/releases/ User guide: https:// github.com/nanovna/NanoVNA-QT/raw/master/ug1101.pdf Since we are using a higher spec LCD, if the touchscreen is not accurate after upgrading the firmware, please calibrate the touchscreen via the menu! Example of measuring a 2.4GHz filter

Since the SAA2 is an open source design, there are many different manufacturers, and some customers may have questions about the performance of our products. Below are touchstone files from scanning different attenuators with NanoVNA-Saver. You can judge the effective dynamics and accuracy of the approximation from the curve. , and the accuracy of the calibration parts we use, the following test results only represent the sample test data of our metal casing SAA2, and do not assume any responsibility for similar products sold through other channels. Compared to the Advantest R3767CG, the U-segment overlap is almost perfect and can be better used for UHF duplexer tuning:

These stages can also substantially overlap:

Measured 2.4GHz filter accuracy can also be within acceptable range

Scan the 6dB and 10dB attenuators on CH0 respectively, we can see that the return loss of the 10dB attenuator is between -20dB and -22dB, and the accuracy of the calibration part and the directivity of SAA2 are very good:

Sweep 10dB, 30dB, 50dB, 60dB, 70dB attenuators between CH0 and CH1 respectively, S21 can get satisfactory results up to 3.3GHz:

NanoVNA-Saver software now supports SAA2
