Hi Lapo, Wait a second. The display is available as R+jX. Just switch to polar.format. And if you desire you can dedicate trace 0 to a Smith plot while you dedicate trace 1 to a polar plot. Of course

Thanks! That is helpful. The fact that the polynomial code to describe the open is present implies he was aware of the situation and at this point elected to put it aside. So for all intent and

I checked the code repo's posted and this is what I think the situation is with the standards: The load is assumed to be perfect - i.e. the assumption is that nothing is reflected from the load. The

Sure Lapo. That is great. However they are all practical representations. In fact why stop there. You could convert the result to its parallel equivalent admittance and provide that as well. I suspect

Hugen has already committed his changes back to edy555's original github repository. Have a look at https://github.com/search?q=nanovna

Lapo Pieri, After compilation it works exactly the same as yours. There is still a problem, an error occurs when compiling if USE_PROCESS_STACKSIZE = 0x200 USE_EXCEPTIONS_STACKSIZE = 0x200 With these

Hi, I think that Smith chart presentation of impedance as <real_part>[ohm] <series cap or ind>[F|H] is not practical in many case of use. So I decide to modify the code to show impedance in

I have added the second drawing that shows a complete rear cover plate that covers the sides.

Folks, A number of you were commenting on maybe using female N connectors on this unit but were concerned about breaking the SMA connectors off the circuit board. I did a little 'doodle' at lunchtime

Yep .. still had no (easier) way of compensating hugen so... and that was my original intention (stare and compare) Jim

So total was $71.90? Please, Jim, once you get the Hugen NanoVNA, compare the two units' hardware and describe the differences, as far as you can! TiA. Den m?n 29 juli 2019 17:58jim via Groups.Io

There is a wealth of good information in these notes. Thanks Larry for the translation. It is clear the developer put a great deal of effort into the project. Reading the description of the work in

Same vendor I used ...Ordered july 3, recieved july 26 ... In order to (maybe) compensate Hugen for his efforts, I also ordered one via "taobao focus" ( "hugen79") .....cost of unit $53.54

Here is an SWR meter (to 60MHz) with Bluetooth Mini60S

There is you metal can, but that was designed to go in the can. Reworking the Nano to go in a can would be more of a pain, because the controles are not laid out in that format. I might get one of

Ed, I got mine from Aliexpress vendor: https://www.aliexpress.com/item/33043060569.html It's a very nice unit, comes in a plastice case with all the attachments/cables/cal and has a battery. It took

Looking over my unit, it's a Worse clone". I am returning it, as some of the measurements are bad., Which website should I use to get the proper unit? Thank you, Ed

Weird. I was just looking at an ad for that sold by StepIR in QEX magazine. DaveD Sent from a small flat thingy
