Sure, I'm an engineer. I've been using professional VNAs for some 40-years. I salute the creators of the NANOVNAs! It works just like the professional units and quite intuitive to me. Keep it up. I ha

Once you learn one VNA, no matter whose or which one, you will be able to use them all. The basics of the instrument aren't that different from the NANOVNA to the very expensive professional units. It

Once you learn how to use about any VNA well, you won't need an "Users Guide". I learned many decades ago on the job using professional HP equipment and have never looked back. The NANOVNAs came natur

Yes, my first "knee-jerk" reaction would have been an audio oscillator and an o'scope. But the noise gen. and SA will give better results in a single plot on the screen. I have run across online audio

A broadband noise source is quite useful without spending much $$. Zener diodes make wonderful noise sources and are easy to home brew into a noise source. That with a spectrum analyzer can make a nic

This would indicate parallel resonance of the inductor as at resonance, the measurement is indicating a very high resistance. The Smith Chart with the cursor would give you the same information. Dave

The Smith Chat is best suited for revealing both resonant frequencies and values of an inductor. All questions are answered in the single Smith Chart display of the measured data. RESONANCE: Where the

For velocity constant I still prefer measuring the frequency of the first short circuit for both an open (reflects as a short) and a shorted (reflects as an open) cable. Average those two. Then take a

Again...... The proper instrument to use for the stated purpose is a spectrum analyzer, not a VNA! Spend the small amount of $$ and get yourself a TingSA. Dave - WØLEV gmail.com@groups.io> wrote:

Yes, The H4 is very popular. I also have one and it's my "go-to" VNA when I need to measure something outside at the antenna(s). However, having 78-year old eyes, I much prefer the larger screen. That

I'd agree. The LiteVNA64 would be my choice as well. When you order any of the NANOVNAs, be sure you also order connector adaptors to go from the native VNA connectors to what your dad uses, for HF, t

So why not just use it with 50-ohm center on the Smith Chart? It will easily show 75-ohms to the right of center on the central horizontal line with a non-reactive resistor. By design, the NANOVNAs ar

Remember that just because you adjust the antenna matching unit (AMU) to allow the transmitter (and receiver) to "see" 50 ± j0 ohms does not mean that you have eliminated the XMSN line SWR. In adjusti
