Firmware file size now smaller?
On the Google drive here - https://drive.google.com/drive/folders/1IRz6E1wlkRyV0u7sbqj0lhWST-GV1szY The firmware is now in folders (I do not think this was the case last week when I got the 900

Re: NanoVNA-Saver 0.1.0
Hi Rune, thanks for the hint! I tried it out right away and it works very well! I have attached the plot of a 200MHz BP-Filter. The calibration is done with full span and 8 segments. Now I can figure

Re: Type pf Touchscreen
I agree; with decent screen calibration and an old Samsung Galaxy Note stylus, I find device menus faster and easier than any VNA software UI, so use software mostly for data capture or TDR.

Re: Another ebay deal?
Probably not long. I am sure there are much more robust connection options available but <$30 for a set of possible uses doesn't exactly seem that expensive (you could make your own of course) but I

Re: edy555 design notes on CALIBRATION sets
Hi Jim - I will try! Yes. Exactly, but I am not about to build a pcb with BNC connectors for each component to measure, and it is IMO not necessary for use below 150 MHz. Not really, but did not

Re: Is my Nanovna broken?
Thanks for the segment suggestion Rune and those off line too, I don't think it was the segment issue. It seems the callibration data had somehow been borked and nothing was correct, once did the 'cal

Re: NanoVNA-Saver 0.1.0
Hi Norbert, For calibration within NanoVNA-Saver, setup the sweep first to be the span you want calibrated - for example, 50k to 1500M. Then in the box labeled "segments", enter how many segments (of

Re: NanoVNA-Saver 0.1.0
Hi Rune, thank you very much for your quick answer! Please tell me the trick where I can change the number of points prior to calibration. I didn't find that yet. I think the following measurements

Re: NanoVNA-Saver 0.1.0
Hi Norbert, the application can run calibrations at far more than 401 points - I have certainly done 5050 points at one point. ;-) But it does this in the application, and not on the device, due to

Re: NanoVNA-Saver 0.1.0
Hi Rune, thank you for fixing this issue! I have a question for you in respect to the required number of data points to measure a band pass filter. With 101 points it is most likely not possible to

Re: Is my Nanovna broken?
Thanks Rune, I'll try both options. BTW this is running Linux & Python 3.74 version at home, work is much earlier so will have to wait I guess until later. I get the same output with the previous

Re: TaoBaoFOCUS (hugen79) order cancelled
Glad you got yours. Obviously I'm not worthy. I have got one now from elsewhere on eBay. And when my sma to n adapters come I may even use it!

Re: Another ebay deal?
Nice idea. I wonder how long those little u.fl connectors will last though.

Re: Is my Nanovna broken?
You tried sweep 50kHz span with 101*10 sweep. I don't think NanoVNA capable below 50Hz RBW... How about give more span with default 101 sweep?
Re: Is my Nanovna broken?
Oh, a different issue: You set the segment count far, far too high (1000). Try a value of 1 first, and see if that helps :-) -- Rune / 5Q5R [email protected]> wrote:

Hi Dom, The application is receiving some weird data from you device - a value of about 2 billion, which is supposed to be in the range -1 to +1. ? Try doing a full calibration on the nanovna,

Of course Larry, you've been a great help thus far! :-) I'll be doing alpha testing for each new version from here on. -- Rune / 5Q5R
