Oooh, si tacuisses ! You try to make believe to be way above it, but: Is that "innocent, unexperienced beginner" perhaps your own point of view? This computer era definitely did not come into

H4 F303 variant PCB artwork updated to 4.2.1 : Update the schematic diagram, the impedance of ch1 is closer to pure 50 ohms

For people actually designing RF equipment, the Smith Chart is a valuable tool. -- Carey Fisher careyfisher@...

I received a NanoVNA-H, firmware version 0.4.5-1-gfbbceca, Build Time: Dec 26 2019 - 19:32:31 today. Finding that there is new firmware, I read the WIKI and downloaded STSW_STM32080 from the ST

Hi Kell, The unit you purchased is the latest version of the 2.8 inch Nanovna. The H4 version has the same RF and operating system design but with a 4inch display and a uP with larger flash memory for

I also just received notice from USPS that the S-A-A 2 is in transit. With any luck I should receive it within a few days. I placed my order on the 8th of March, so given the current state of affairs

The Smith chart assumes that the impedances have been "normalized". Just divide by 50 to get one in the center Bob [email protected]> wrote:

Thanks for the reference. Not bad first response, appreciate that very much. Cannot say much about the rest of them. In future I will limit my posts to "how much is 1 and 1 " , asking to avoid sermons

Thank you for the suggestion, from which I see now that I have to correct what I wrote, as follows : for the newcomer, the whole Great Idea of that very difficult to learn Smith Chart is just of

I believe that the scale in question is linear... but it's measuring the "reflection coefficient", not "impedance". It has a value of -1 at the "zero ohms, short circuit" end, a value of 0 in the

Like a slide rule. Accurate enough to get useful results and visualize what's happening in a system. You can be much more accurate by using SimSmith. -- Art Greenberg WA2LLN art@...

Hi, $Subject has arrived to me today. Hope I find some time to check and test it with NanoVNA-Saver soon. ciao Holger (DG5DBH)

Smith Chart : In this computer era, this extremely high-effort demanding, highly-inaccurate, old-time graphics tool became completely obsolete, because it is a totally useless one in every other

Because I dropped a zero. :-) For example, the point 1.2 + j.7 is really 60 + j35 in a 50 Ohm system.

Why isn't the example = 60 + j35 ??? <snip>
