Hi Hugen Thanks Pse did you mean slightly better below 100Khz or below 100Mhz ? 73s Nizar

Thank you for your information. Kees, PE0CWK Op 30-4-2025 om 04:05 schreef Hugen via groups.io:

Hello, after NXP discontinued the SA602A we designed a compatible chip for the continued production of the NanoVNA. This chip has a slightly lower noise figure, but also a slightly lower IIP3. I

If my memory serves me correctly the major difference between the ne and se version had to do with the temperature range they were spec'd over. wrote:

I've posted a new version of the plotter with admittance here: https://k6sti.neocities.org/splot Brian

I think that having two grid colors is pretty important to help visually distinguish between the impedance and admittance grids. Traditionally impedance has been plotted in red and admittance in green

That's what I was hoping, Don. It was so easy to implement! I think I'm going to leave two grid colors for another time. I could do two gray intensities without much trouble, but I don't think that

There is a hook/mouse click "box" in nanosaver to reset any previous cal. Look for it and click it. Dave - W?LEV [email protected]> wrote: -- Dave - W?LEV

Analog Instruments (Phillip Smith's firm) sold expanded Smith charts of 3 kinds: expanded about the center with two magnification factors IIRC, and expanded about the high- and low-impedance areas,

Here's what I have at the moment. I can see that two grid colors are important so let me see how much trouble that is. Brian

Try again...

Here is an example with the display and the captured movement to implement a matching system.

Yes, that is helpful 73 Jeff G8HUL

I see. Displaying both grids simultaneously is easy. Do you also need impedance and admittance values displayed at the same time? The images show what now happens when you click the mouse wheel. Brian

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
