Erik,The Japanese Ham on twitter (I put photos in the files section) was running CH0 from an ext supply per the top photo. What would happen if you raised the supply voltage? It can take 8v max.?The

Those 2 resistors are only required if you are using a usbc to usbc cable on a usbc computer port as they tell the computer the type of device being connected. If you're using a usb3 to usbc cable on

I had uploaded a zipped file in the Forum's file section that has info on the matching pad, if you would care to look at.? On Mon, 14 Oct 2019 at 12:14 AM, Starsekr via

Hi Herb The s1p and s2p files are plain txt files so you can open then directly from Excel, choosing a separator then you can save tocsv. However the first 4 lines are text telling what type of data

If you change just firmware for Z0=75 ohm it won't work for 75 ohm properly. It may show you proper resistance for zero reactance circuit (such as dummy loads and resistors). But if your circuit

Hi David, the firmware is written in C. I don't know that there are formal constraints, other than what the license (GPLv3) puts on it. I personally, as an application developer, have a few

There are some features that I would like added to the firmware connected with calibration. I don’t mind making them public, but are quite happy to just add them for my own use. Are there any

Indeed, that is the question, and I >>suspect<< is why some notice more reliable nanoVNA connections via USB-2 hubs than to USB-3 hosts. USB-C connectors are mechanically symmetric. In order for half

Hi ... I would like to try You new nanoVNA v1.03 TD Rb4 (like TDR ...) Thank You, Vlatko

Hi Here is how to split "any somewhat formatted" text file using Excel 2003*. The procedure has been the same since the early 1990'ies: - Open the file in Excel - When the "Text Import Wizard" shows

Changed the offset from 5kHz to 12kHz and running the nanoVNA directly from a linear 5V power supply. Even with USB connected the latter makes a substantial difference in noise levels Guess adding

Jacon, if the resistors are missing, what does that do to USB communication? Are they just for using the USB as a sink (load?) for charging a battery through the USB port? Without them does the

Herb, The S2P file can be in decibels and phase angle, or in real and imaginary part for each component. In this case, I think "RI" indicates real and imaginary for each of the four S parameters (S11,

Herb, As you know S-Parameter files are actually text files. The line with the "#" character is the format string for the file. This may or may not be the first line in a file. In the case above, the

I started this topic because the original thread got hi-jacked to antennas matching. :-( H Walker posted in Msg #4702 /DMR, /Thanks for your contribution. A previous DFU file was uploaded for making

QRP, I had looked at the S2P file using a text editor and could see the values were space delimited but the none of the columns were identifiable to me as the S21 log magnitude values displayed by the

What is your modification exactly?

S1P and S2P files are CSV compatible. You can just copy it's content into excel
