Accuracy of the nanoVNA units

Bob Shaw All Messages By This Member #922 Has anyone measured some high resistive and inductive/capacitative loads and compared the resultant reported impedance with the results of the same loads on a known more accurate VNA? This would be interesting and relatively easily done if you have access to a professional grade VNA (which I don't).
alan victor All Messages By This Member #924 That is an item I am in the process of doing. Keep in mind the method of measurement of components will influence their accuracy. There is shunt mode, series shunt mode and series mode only. Depending on the \|Z\| your results well vary significantly. Alan
F4WCV All Messages By This Member #932 There are good designs for 9:1 or higher ratio baluns out there using the right ferrite cores e.g. types 77 or 2401. My previous remarks about the 800 ohms max could be extended using such a balun. Any comments? toggle quoted message Show quoted text -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Bob Shaw Sent: Sunday, August 11, 2019 1:31 AM To: [email protected] Subject: [nanovna-users] Accuracy of the nanoVNA units Has anyone measured some high resistive and inductive/capacitative loads and compared the resultant reported impedance with the results of the same loads on a known more accurate VNA?
