WebDec 2, 2024 · Dec 2, 2024 #1 Wish someone will assist Measuring the Q.. Xl/r . Also, the nanoVna has Q function But my coils all give low Q.. Less than 70 and can not understand why.. The coils are from kitsandparts Have used wire gauge 24 and 26.. still can't get high Q at 7Mhz...not even high from 1Mhz to daylight What can do? Thanks ericgibbs WebNanoVNA Isolation Calibration : r/amateurradio by aacmckay NanoVNA Isolation Calibration Hello, fellow NanoVNA users. I just received mine and I was running through calibrating it. Since it only ships with one 50-ohm load termination cap how do you do it? Just skip it? Or did you order another 50-ohm load? hart wynd bannockburn

WebnanoVNA has a directional detector behind port 1 that can independently measure the magnitude of the V incident and V reflect voltage. The ratio of the reflected and incident voltage is the Scattering Parameter matrix element S11. The DUT may allow some of the incident signal to pass through to its output as a function of stimulus frequency. WebMar 13, 2024 · My advice would be to just calibrate the nanoVNA and measure the transformer in a suitable test fixture with the nanoVNA to get s11 and s21. Then get the reverse s12 and s22.
