Yes, magnification in particular around the Zo of the chart is quite useful and that is a feature available on several simulators. Conversion from S to mS or even uS is also an automatic process to

The whole point of displaying both impedance and admittance charts simultaneously is that it make visualizing matching much easier. Adding series C moves CCW on the impedance chart, shunt C CW on the

Something else I've wondered about. This is an 820 pF capacitor from 50 MHz to 4 GHz. There's not much to see. Would a magnification function be helpful? Or do people just not worry about detail in

Here's how it looks at the moment. I'm thinking of providing a different background color for admittance, but the grid is so different that I'm not sure that's necessary. Brian

I don't quite follow this. You click on Admittance to plot admittance. Otherwise it plots impedance. The grid and marker annotation change. The curves remain the same. In looking at admittance for

Here is a portion of the immittance chart. Less contour density is still workable. A toggle feature is available on the program I use to assist in clarification.

Yes on mS.

To facilitate matching the 2 charts are overlaid in 2 colors. The immitance chart used red and green and the one I used had less density on contours. Consider the possibility of a toggle between them.

I've got the Smith admittance plot running. I assume people use mS rather than S to avoid tiny numbers. Is that right? Brian

It's a false positive. First of all, download the latest security intelligence update from Microsoft. I just did, and it does not flag the file as a virus. Another way to check is to give the URL

Brian, F.y.i. When I click on the word program on your page https://k6sti.neocities.org/splot.htm then my Windows 10 pc? finds a virus and does not continue to download. 73, Kees PE0CWK Op 29-4-2025

Mark, How is your H4 connected? If a serial USB cable, then COM port number rather than IP address. Device Manager will show the COM ports you have. 73, David GM8ARV -- SatSignal Software - Quality

Did you go through those calibration steps on the application or the Nano? If on the application then you must be connected successfully. You calibrate on the Nano only when you want to use it as a

Using nanaovna-saver, on a -f, I noticed that sometimes the circle on the Smith machine (on a simple capacitor, for example) could be larger than the grid circle. Now, systematically, even before

I have the NANO H4 connected to my laptop and the app is running. However, I see next to the <DISCONNECTED> is a field where I am supposed to enter an IP address?? I do not know the IP address or why

Why not have a serious read of the information in the WiKi on this site? There are several excellent guides there. Dave - W?LEV <d.milivojevic@...> wrote:

It depends on how different the results are. Remember, the FW interpolates Saver can do unlimited (in theory) number of points. It will just do the required points in segments. For H4 that would be X

I've posted the s-parameter Smith plotter here: https://k6sti.neocities.org/splot.htm Please read splot.txt to learn the obscure tricks (like how to display a Smith plot!). I will try to free up some

Yes Reset first and then calibrate If what you are measuring does not have sharp valleys and peaks in SWR then you can just reduce the stimulus range on some NanoVNA's (like the -H and -H4) and the
