The NanoVNA-F V3 Vector Network Analyzer with 4.3" display is of extremely high quality. The display is smaller than I expected even though the size is clearly listed; the size can be a barrier for older eyes as there is a lot of information available on that tiny screen. I have tried to understanded what about this device is "upgraded" as the listing title suggests but this seems the same model as those which are not listed as upgraded; perhaps they are referring to the range upgrade of the V3 over the V2 which is a nice feature. The product works very well and is excellent for antenna analysis.

Wildly out of spec, even after proper o/s/l calibration, and therefore useless.The power output levels seem correct across the full frequency range, so the problem might be related to the power detector on the input signal path. For example, a precision wideband Amphenol 20 dB attenuator shows up as having just 12 dB S21 loss across the frequency range, even after o/s/l calibration. Similar poor results are replicated with other very-good microwave-grade attenuators ranging from 3 dB to 40 dB, all of which this NanoVNA show as having substantially less loss than reality. (All attenuators used for the test were separately verified using an HP bench VNA.)

Mi ha permesso di misurare induttanze e capacità , inoltre ho potuto testare vari filtri, ottimo per me che lo uso per hobby.
