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.

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

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.)
