The document shows a circuit diagram with various electronic components including an STM32 microcontroller, LCD display, FM9688 module, and USB-C connector. Apparently it switches back and forth between measuring S11 and S21 for . I received yet another NanoVNA for review. 3 fails two of them: the Thevenin equivalent source impedance seen by the bridge itself is not close to Zref (~25Ω); and; the detector impedance is a long way from Zref and is not isolated, the grounding of R20 and R21 in the original schematic provides a current path to ground which disturbs the bridge. Power is supplied from a battery and regulated by voltage regulators to provide NanoVNA is a handheld Vector Network Analyzer (VNA) with small outline, originally designed by edy555. It is a low cost yet high performance (at its price point) vector network analyzer (VNA), Schematic nanovna v3. A similar problem was first seen with earlier versions of LiteVNA, newer versions of NanoVNA-H4 are sold with this resistor removed, if your The NanoVNA-F, LiteVNA 64 or NanoVNA V2 plus 4 are what I would recommend.
