Hello All,
I have attached a pic of the NanoVNA Saver Display Charts options.
Is there a way to select those 5 options in NanoVNA-APP?
|S21|
S21 |Z| shunt
S21 |Z| series
S21 R+jX shunt
S21 R+jX series

NanoVNA Saver 0.6.2 shown
NanoVNA-App v1.1.215 using

Thanks in advance,
Mark

NanoVNA app does not calculate/plot S21 impedance measurements. BTW S21 impedance measurements are not very accurate using NanoVNA's because they do not do 12 point error calibration and do not have precise 50 ohm source and termination impedances. You also need a good test jig or stray capacitance will greatly affect the measurements. If you search the archives of this group you will find many discussion posts on this topic. Using a -H4 I have found that i can make fairly good measurements from 2 to 3000 ohms impedance using the s11 shunt method.

Hi Mark, Roger,

For NanoVNA-App (DiSlord version) these informations are calculated, but not plotted.

They are displayed on the Info Panel (info button must be turned on), right side at the lower part. Compared to my Libre Office calculation sheet, values are perfectly relevant.
