Thanks , nice video. Question, I have heard that you can scan more data points when using NanoVNA-Saver, more than the 101 standard points for a given sweep. What I have been doing, as long as I know what frequency I am interested in, limit the sweep to narrower bands, or use the center freq. Is there a way to use more data points over a given range via NanoVNA-Saver, or was this just mis-information. Thanks again

[@sphchurch]

Good job as usual. Ordered an H4 from Amazon. they left out the open calibrate unit.

[@TheSmokinApe]

Ugh, that kinda is a kick in the pants.

[@chuckpiercy]

Thanks for a great video. Curious: does saver allow you to print plots?

[@TheSmokinApe]

Yeah, you can save the graphs to your PC and you can actually screen cap the VNA 👍

[@MIKEM-tr1ix]

Very helpful introduction! I recently purchased the SAA-2N, and the shading for a selected band is always gray. I can't change the band color, as you demonstrate in this video. Is the SAA-2N not cable of selecting a custom color for the band shading?

[@TheSmokinApe]

It’s a setting under display options 👍

[@jbgreer]

Almost a year late, but I got around to following up on this video. For reference, I have a NanoVNA-H. Besides following The Smoking Ape's Excellent Guide [ aka TSAEG for all the cool kids.... just rolls off the tongue ], I also found the NanoVNA group.io site helpful, thought a little overwhelming at first. My experience was marred by the fact that I do work on other STM32 boards and had inadvertently loaded a conflicting USB driver. While I was able to use the other driver to successfully update the firmware on my device (DFU), the USB driver did not enumerate the device as a com port in Windows 10. In my case, I saw USB device driver entries for ChibOS. I nuked that driver from orbit (it's the only way to be sure), and reinstalled the STM32 USB driver. NanoVNA Saver is now working, and I'm enjoying the more complete (and more legible!) display of data. You're a scholar and a gentleape. 73

[@TheSmokinApe]

Ugh, I bet that driver issue was a pain. NanoVNASaver is the way to go, so much easier.

[@user-zn2hd5qw4c]

Hey. Please tell me, besides calibration, is it possible to save the setting of the position of markers and frequencies. In order not to re-expose everything every time you start ...

[@dreupen]

Great video. Question: I have been recalibrating each time I reset the frequency range. Why are you not doing this? Sorry if it is a stupid question.

[@TheSmokinApe]

You should calibrate or used a saved calibration when you adjust the frequencies. I didn't for brevity... It's less of a problem if you narrow the bandwidth from a previous calibration.

Hey Barry, I don’t have that video. Have you tried NanoVNA-Saver?

[@FStewartIII]

great video. Have you done any work with "estimated cable length? if so what were your thoughts about accuracy?

[@TheSmokinApe]

No, I really haven't played around with it. It seam that you either need to know the length or the velocity factor which if I knew that, I am not sure I would need the VNA...

[@visitinghere]

Thank you! I now have my nanoVNA running on my computer thanks to you! Now I need help in interpreting the information I have. Gain in db vs losses? I got the (V)SWR, but there’s more than that here! Thanks again for your help! 73 de AE1R

[@TheSmokinApe]

visitinghere glad it’s up and running, the different information is relevant to what you are measuring. Are you looking at something in particular?

[@visitinghere]

TheSmokinApe well, I have a long run of RG-8 (270 feet!) and ran a TDR test. Part of my NanoDNA results showed Return Loss of -15.7 dB. Do I divide that in half (the signal goes up, then is reflected back) or break my piggy bank and replace my feed line. Sorry, Noobie question.

[@TheSmokinApe]

[@visitinghere]

[@jessicakelz2379]

Hi! Fantastic video. I appreciate the introduction to this tool! Do you know if this program is able to be used to record and export the log magnitude of the reflection coefficient and frequency as an antenna is perturbed by a conductor inside the resonant cavity? This would be tremendously helpful in an application I am helping to develop. Thanks in advance!

[@JamesHindsW5ATJ]

Great video! Did you say you can not sync the things done on the actual Nano with the NanoVNA software? For instance, if you calibrate the Nano thru the software, that's only good if you are taking measurements thru the software? If you were to take measurements with just the unit you would have to re calibrate the unit? Thanks

[@TheSmokinApe]

That's my understanding, you calibrate on the device when you use it without the PC and on the PC when you use NanoVNA-Saver 👍

[@TheSmokinApe]

You could do that and yet it would be closer.

[@paulmaine6433]

What headset are you using? Good

[@TheSmokinApe]

It was a Logitech, sorry I don't have the model number

[@PARTner91]

The USB charging cable for the Nanovna doubles as a data connection cable between the Nanovna and a PC/Mac/Linux machine. So, when you connect the Nanovna thru that cable to a PC/Mac/Linux computer for use with the Saver software, does the computer continue to also charge the Nanovna battery at the same time? Or, when the cable becomes a data connection, does it cease to charge (and therefore the Nanovna’s life is limited since it will eventually run out of power)? That’s a lot to try to explain - hope my question makes sense.

[@TheSmokinApe]

It does continue to charge 👍

[@PARTner91]

Thanks @thesmokinape !

[@bruceweight7319]

Hi Just wondering? Lets say I am testing some balun's transformers etc. and I am using one of the little cables that come with the unit to connect to the balun transformer etc., should I calibrate it with this cable attached so as to eliminate that influence from the calibration? I have done this and when the calibration is done and you connect the 50 ohm load the marker snaps to the center dead on at 50 ohms and when you go open it goes out to the edge and when you short it it goes to the other edge right on. Where as if you don't include the cable and calibrate right at the machine with no cable and then add the cable and put the short, open or load on the little piece of coax it shows some capacitance etc. on the reading so that the stub of coax is added into the picture of the device under test. Do you know, if there is any official ideal way of doing this?

[@TheSmokinApe]

You should use the cable in the calibration if you only want to measure the DUT or Device Under Test. Calibrate without it if you wanted to include the transmission line in you test.

[@jimdurant1192]

Hi, thanks for great tutorial. I am trying to calibrate my efhw. Should I adjust the calibration for the coax between the antenna and the nanoVNA? Would having a rf choke effect that calibration?

[@TheSmokinApe]

Hey Jim. I would calibrate the VNA at the output of the VNA and test the antenna system where the radio or tuner connects. That way you see what they see what ch is important. You could measure at the antenna feedpoint but you miss the effects of the coax / choke. Of course you could measure and or calibrate at the other locations if you are concerned. Thanks for watching 👍

Is there something I can do to easily adjust this? Obviously a tuner, but it would be nice to have something else in the bag of tricks. 73 Jim

[@TheSmokinApe]

The 100pF cap should help, I am not sure if you have that or not. I have seen some people recommend 120pF, but I have tried that. 15 is a 3/5 harmonic of 40, so you might want to adjust the "resonate" point on 40 to be inline with 15...

Sorry about the screen, I most use mine with the software as well 👍

[@bobc205]

nyworker, try this to get the screen working. ( I did this on my NanoVNA SAA 2N) Open it up and slide the unit out of the case. Then find the inch-long ribbon connector for the screen and lift the black clamping bar, then run a plastic tool along the edge of the bar. This reseats the pins of the connector; flip he black bar back down, turn on the VNA and try the touch calibration step. If the connector is reseated properly, you can reassemble the VNA. I learned this trick from repairing a couple of iPods that use similar ribbon connectors. Or if that doesn't work,or you don't want to mess with it, the VNA makes a great bench unit attached to the computer. Good luck! 72/73 de k1qed, bob.c qrp 4evr!

I can not get the NANOVNA-H to work through any com port. The com ports do not show up on my Dell laptop Studio running Windows 10. All I can get is software that is the code. I've been out of coding for a very long time and did not keep up with it. I could not find a .exe program except version 3.8. 3.9 is all code, as far as I see it. I only have a 3 USB ports and one is used for my wireless roller mouse. The other cable is useless to me on this. I have an 2 very old Macintosh computers and the Windows XP is on this Mac that I'm on.I know Mac better than Windows operation, but I have learned allot. With this, said, I have to figure out what happened to the list of the com ports. It is just not showing up, but other programs like fldigi works with com 5, where the Nano does not work there. I think that about covers it with my frustration of it all. I am on Windows XP now through Parallels. Thanks for listening. //... Joe

Are you sure the USB cable is good?

Hi, I cannot find a way to install nanovna saver. Everything I find is old and does not match what I get on my github screen. Can you give me a current URL to install it on Windows 11? /Thanks, wb7wbw, Jerry.

[@TheSmokinApe]

Hey Jerry, try this: github.com/NanoVNA-Saver/nanovna-saver/releases/download/v0.6.2/NanoVNASaver.win.x64.zip

[@wb7wbw-l2p]

Well, that worked. I downloaded the .zip file and extracted it. Then I spent an hour or so trying to open Nano Saver with no joy. Is there a .exe file or what?

[@TheSmokinApe]

there should be an exe in the zip file

[@wb7wbw-l2p]

@TheSmokinApe There was not. If I remember correctly I just double clicked nanovna-saver main after I unzipped the file I downloaded. A very nice gentleman on the Montana Ham Radio Facebook group helped me out and I've got it running

[@wb7wbw-l2p]

Thanks for all your help!

[@perspectv1]

Well, I am completely stuck. The file is not where you show it is (they must have moved it), and all 3 downloads that I could manage to find will not install, after 3 hours of repeated attempts in spite of following all the instructions. Is there just a simple .exe file I can download and install without having to go through files and directories only to hope I have the correct one? The zip files are the worst, I have no clue what to do there. All this knowledge and expertise, and we can't get a simple downloadable exe file?

[@TheSmokinApe]

Download this and then right click and pick extract all. There will be a new folder in your download location, in that folder is the .exe

[@perspectv1]

@@TheSmokinApe Not finding what you mean by "Download this". There is nothing there, or some formatting did not go through to click on.

@@TheSmokinApe Thanks for the file. I found the exe, extracted, then attempted to install but I got "Unhandled Exception in script". There was a DLL error while importing QT Widgets. The specified procedure could not be found. I will have to figure this one out because at this point I think it's my computer. Oh well, maybe some day when I get time.
