Hi, From Kurt very good measurement with good calibrated s1p file used, I interpolate several point. Original data is 101 point. See the attachment, what's happening if I modify the points to 100,

Hi Ron, Thanks the reply, that could be the problem. Many clones exist, maybe my Hugen like (not know) device calibrators not same than others. I try use nanovna default 50fF C0 or data from Kurt

You need to load the instrumentation library I am running latest Octave on W10 -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files Erik,

Hi Erik , I tried to use the Octave code , but i'snt works. Wich version of Octave are you using , and wich OS. May be my version of Octave 5.1.0.0 on win7 is not supporting the serial function. any

Lajos, I'm NO expert on NanoVNAs, but I believe the difference you are seeing is due to 2 factors: 1. the total Over All Length of the 2 parts or 2. the different dilectric constant of the 2. ron N4UE

Hi, Great idea the higher resolution graph on nanovna saver. I mesured the very non ideal indoor 40 band antenne. The goal construct special tuner to shift 20 meter band electrically. I sweeep 6-15Mhz

Hi Kurt, Thanks for the detailed reply and your other post on wvna calibration method. Very useful for me. I use female open, not male open, not a big difference, but i not know why this error exist.

#86': UPGRADE : On the Results of Measuring Two-Ports Using Only [NanoVNA] Channel [CH0] or a [LeastVNA]. - #86: On the Results of Measuring Two-Ports Using Only [NanoVNA] Channel [CH0]: 16 December

Using the matlab script from QRP I created a rough Octave script. https://github.com/erikkaashoek/NanoVNA-MATLAB The script can send commands to the nanoVNA and read S11 and S21 Nothing special but it

Not really; Octave Forge has some signal processing https://octave.sourceforge.io/packages.php creatingrf [@] gmail.com has some RF support for Octave: https://rf.helpingcreate.com/cgi-bin/octave.pl

I have the Octave interface to nanoVNA working and wanted to work with the data All Matlab code I can find uses rf toolbox Is rf toolbox (or something equivalent) available for Octave? -- NanoVNA

Hi Alan, I did some modelling and there are quite a few places where errors can creep in. I was a little surprised on the significance of Tx driver source impedance and balanced Rx output loading

Hi Allison Sure they will work fien with thee NanoVNA as the difference in offset delay is very small as the NanoVNA is designed for ideal calibration kit except the open is compensated by 50fF. But

Hugen, What will be the price of the new version? And when it comes out, will the older version still be available? BruceN, K4TQL -- *"To invent, you need a good imagination and a pile of junk"* --

Hi Rudi, The MATLAB T-check script is part of a package of scripts written by Dick Benson, W1QG, and downloadable from the Matlab Central:

Allison, Dave, and Kurt, many thanks for your replies. Dave -- thank you very much for the "flush thru" description. That explains a lot, and it was a key bit of info that I lacked. Kurt -- I'll

I would like to thank all the replies to my initial message. Unfortunatelly, the firmware was an old one that didn't allow me to go into a config menu. I also made sure to jumper the boot0 and Vcc. In
