Dave: I understand. A nanovna is not a good idea for AF, note the frequency steps of internal generator, its impossible to use it. May you use an audio oscillator and scope. Depends on your available

I don´t build an optimized coil I just a made a coil. The idea was a very simple setup to show basic measurements (L, Q , Cp). I talked a cap of one isopropyl spray I made 4 holes and I wound a coil…

You can usa an HP8903A audio analyzer… is cheap and works very good. You can sweep up to 100KHz Ing. Patricio A. Greco Laboratorio de Calibración ISO 17025 AREA: RF/MW Gral. Martín Rodríguez 2159 San

Biran : I downloaded the program and I entered the values of my measured inductor Leq= 21.2 michoH , this is very good result. I suppose the Resistance would be computed via skin effect. For any reaso

Brian: All depends on your accuracy requirement , how you build your calibration standards … for special case of serial resonance you can use 2 ports but you can only measure this frequency. The self

Bonzo , this is a different concept. I say reference plane because is the way to define the measurement point. Its clear that the wavelength is bigger than normal working dimensions in this case , but

VNA must to be calibrated to perform any measurement. You measure at reference plane no matter the internal impedance of VNA , this is the part of magic of this instrument. Ing. Patricio A. Greco Gral

Hi! I sent a post showing how to measure resonance and self resonance and I calculated all parameters of a resonant circuit using almost any VNA. The self resonance is the parallel resonance when you

This is the right way to measure with VNA.

A Choke is not more than an inductor. It should be measured as any other one.

230KW … this is a lot of RF power !! Ing. Patricio A. Greco Taller Aeronáutico de Reparación 1B-349 Organización de Mantenimiento Aeronáutico de la Defensa OMAD-001 Laboratorio de Calibración ISO 1702
