David, I forgot to acknowledge the fine work you have done on the SNASharp application. I couldn't resist the D6 board at its price point and it probably would have joined a host of other boards in my

Hi Larry, Please refer to the forum Wiki. There are a number of application note and reference links there:??? /g/nanovna-users/wiki/External-links Refer to the Smith Chart

Hi Karsten, I assembled all of the available (at that time) firmware that you see in the Files section.? It was done at a time when things were scattered around and forum members were asking where to

Okay, I have a NanoVNA ordered and I have a VNWA. I know the differences between X, R and Z. What I do not understand is Xr, Xp, Rr, Rp, Zr, Zp, |Z| etc. I know the r and p mean series and parallel

Rune, Seems at least a few members are requesting the capability of taking and saving a screenshot be added to NanoVNA-Saver. The python code is included in edy555's nanovna.py script. From my

@all, is there a collection (best would be feature table) besides the Wiki-Page (or one I did not find) where all different Firmwares with the features (my be release dependent) are compared as well

Hello Karsten, The software takes readings from the NanoVNA, and displays them and does calculations on them. The readings taken are the S-parameters, S11 and S21, so any settings for traces on the

Hi Jean, thank you very much! It's exciting to hear what uses people find for my little hobby software project! -- Rune / 5Q5R

Hi Lucio, NanoVNA-Saver reads the current frequency span of the NanoVNA, and uses that as the default. It does not read any other configuration values from the NanoVNA, yet anyway. Thank you for the

Hi Herb, I'm glad you're enjoying that second marker :-) I don't know what the group delay graph is trying to tell you .. I just write the code ;-) -- Rune / 5Q5R

Hi Karsten, I answer partially instead Rune's. The limitation of 100Hz comes from the firmware, and maybe even hardware. Another solution to determine the motionals parameters of a crystal is to use

Hello Rune, I am quite new to the group and am already scanning all the messages for information. So please excuse, if I missed the information I am now askig for: Which functions are taken over from

Thanks to jwd270 and Joe St. Clair AF5MH, I placed my order an hour ago, I've downloaded the lastest firmware and will look into adding the battery voltage diode. I expect to use mine with a netbook

Hi Rune, Thanks a lot for this fantastic software. The newly added TDR markers are very useful when dealing with roof antennas. :-) Great job. Thanks again Jean

@Rune Broberg forgive me Rune, maybe it has already been said a million times but I still have doubts. Let's say I have the nanoVNA turned on "Recall 4". I connect NanoVNA-Saver to the device and the

I'm using eclipse to edit and the github gui to sync with github. Apart from remembering to save the files you edited because otherwise the make file will not do anything this works well. For eclipse

Thanks. Interesting to see.

Rune, While verifying a cable that I just constructed, I noticed that you had implemented a second marker in the TDR graph. Thanks a lot! Its nice to be able to mark other anomalies, in addition to
