NanoVNA handheld Vector Network Analyzer (VNA)

NanoVNA is a small handheld Vector Network Analyzer (VNA). It is equippedwith lcd display, portable device with battery(battery not included). This project aim to provide an RF gadget but useful instrument for enthusiast. The device hardware offers 50k-300MHz frequency range that can be expended up to 900 MHz (with somewhat less dynamics on higher frequencies). It has built-in touch display. You can use the USB interface to connect to computer communications or connect standard 5V charger charging. This looks like a very interesting piece of open hardware that I need to test some day because it cost only around $50-80 depending where you buy it:

    Bypass capacitor S-parameter models: What you need to know–What-you-need-to-know

    S-parameter models are small-signal linear behavioral models of a component or circuit with any number of ports. They can easily capture frequency dependencies. S-parameters can, for example, properly capture the decay of capacitance, the complete variations of effective series resistance, and the lowering of inductance, as frequency increases. They can even capture secondary internal resonances. Between a Start and Stop frequency, the complex values of the S matrix elements are listed at a series of frequencies.

    I bought two NanoVNAs, and either both are not recognizad when conected to my W10 running PC.
    Any help?
    Thanks in advance,

      For me it was just Plug&Play when I plugged it to my PC. It was properly recognized as serial port.
      Check the driver issues and USB cable would be a good idea to start I think.

    The NanoVNA-F is the improved version of the eponym open-source antenna and vector network analyzer (VNA) which covers HF, VHF and UHF bands from 50 KHz to 1000 MHz.

    This new version of the NanoVNA has a larger IPS TFT 4.3″ (10.9cm) touch screen with a resolution of 800×480
