Re: Calibration of H4

F1AMM
 

My question is it necessary to have the Nanovna set to the
frequency to be tested and calibrated before connecting to the computer and Saver
software?
Hi
I asked myself the same question as you. Obviously not: it is not necessary to calibrate the box before. You do with Calibration from nanovna-saver. I'm not smart enough to have known how to use the "normal" calibration so I do with the wizard.
I assume that you have understood correctly that the short-circuit, open and load operations are to be carried out flush with the equipment to be tested; for example at the end of the aerial cable (by disconnecting the aerial). Without putting too much sweep in frequency, provides wide and with many segments (each of 101 bars). Note in the file name the frequency band and where you did the calibration. Nanovna-saver says nothing if later, your measurement band is not in the band used during the calibration. Obviously the measurements are then tainted with large errors.

It is possible, with Excel, to correct the calibration file to smooth out the false (noisy) measurements.

Calibration of H4

 

I could not find any threads that answered this question so here goes. I have seen a lot of videos of calibration of Nanovna using the Saver program, some show calibration only in the program itself and others show calibration in the Nanovna prior to connection to computer and then in the program. My question is it necessary to have the Nanovna set to the frequency to be tested and calibrated before connecting to the computer and Saver software? I am primarily testing swr on homebrewed 2m and 70cm antennas for my own use. Thanks for any advice.

Re: Updating firmware from linux with the ST Micro CUBE programmer #linux

 

Between that, and ST having end of life'd the dfu tool, at some point, it will likely become the only option. As other have noted, though, the idea of lean, efficient, *small* software appears to have died . . .

In any case, that's why I used Cube - the one product will work on many platforms. Huygen has .bin files of his distros, so all that is needed is for DSLord to drop .bin images as well as the .dfu (Since Cube can't read .dfu *files*, yet programs via the dfu *interface* . . .) Yeah, I could build to .bin, but am generally unmotivated to setup a build environment for this, since I don't plan to do NanoVNA development . . .

Thank you very much Roger. It works now in 0.3.10 ¨C Win7

Already with the language, I have a lot of difficulty finding my way around in github.

nanaovna-saver is a magic tool for me. I had a hard time figuring out what the baseline measurement the nanoVNA-F bridge was doing. Through nanaovna-saver I see that everything is recalculated from S11 since it is the only information that is available in the .s1p files

I tried to install NanoVNA-WebApp-nightly-6e03c6c.apk on my tablet but maybe my system is too old:

Android Version: 5.0.2
Kernel version:
3.4.0-10239154

Re: NanoVNA for RFID design

 

The ST rep said to just replace the short calibration of OSL with the coil attached. "short" calibration of the coil. Makes sense now in hindsight. Anyone have insight into the "conversion to 'Z: Reflection'" bit?

Re: Updating firmware from linux #linux

 

Yeah I finally got it, I had to add the alt=0 to the command line, and then everything was fine. Now updated to version 1.1, just have to figure out everything that changed and how to use it.

Trust me, *dfu-util* *does* work! (The ST Cube seemed rather overkill for very occasional firmware updates!)

I use the ST Micro Cube programmer, and the .bin images from Huygen native on Linux and it works fine. (Search the group - I posted a full "HowTo" procedure a month or so ago). Considering that ST has dropped the DFU based tool in favor of Cube, seems to be a logical direction in which to make a move . . .

Re: Updating firmware from linux #linux

 

Chuck,

it's most certainly possible to update nanoVNA firmware under Linux. There's a *description* at /g/nanovna-users/files/Nano%20VNA%20Saver/nanoVNA-H4%20software%20support%20under%20Ubuntu.pdf.

The listing from *dfu-util* is roughly correct. I've only got an H4 to hand, which offers slightly different results:

~$ dfu-util -l
dfu-util 0.9

Found DFU: [0483:df11] ver=2200, devnum=16, cfg=1, intf=0,
path="3-4.1.2", alt=1, name="@Option Bytes? /0x1FFFF800/01*016 e",
serial="205230502031"
Found DFU: [0483:df11] ver=2200, devnum=16, cfg=1, intf=0,
path="3-4.1.2", alt=0, name="@Internal Flash
/0x08000000/128*0002Kg", serial="205230502031"
The two entries refer to two different memory areas. It's likely that there was an issue with the command incantation. The *.dfu* file is to be preferred for the simpler command line necessary (less likelihood of a mistake.)

HTH, 73, Stay Safe,

Robin, G8DQX

This may be of interest to you. The "official" Saver 0.3.9 and Saver 0.3.10 do NOT run on WIN7 because the version of Python and the QT library are not compatible.

It is used when measuring inductors and you wish to know the shape of the complex permeability curves. This is useful when trying to determine the characteristics of an unknown ferrite toroid. It was described by the original NanoVNA Saver author when he released version 2.0. If you read the entire thread you will see questions about it and how it is used.
