On this Ft measurement, I think you should try to measure the full set of S parameters. This simply means turning the test set (whatever that currently is) around end for end and measure S22 and S12.

Rune has the S11 values converted to Z series complex, real and imaginary. He provides the Q as well and this is the Q series value. You can transform from series to parallel and he does this

Hi Maurizio, I'm glad you're enjoying the new version :-) I agree that calibrations should save the start/stop/segments/averaging. It's a great point. I don't know if I want to overwrite whatever

Hi Martin, I *think* the Cs/Ls you are after is already shown in the marker data display? It's what's shown as "L equiv."/"C equiv." The series resistance is the resistive part of the impedance

Hi Norbert, I'll definitely not make a flexible display window for now, as the way the charts are built is not at all compatible with this approach - sorry! Maybe in a far future when everything is

Hi, I used to work for a passive component manufacturer. Had a tiny experience with 0402. Hearing aid manufacturer used an 0402 cap to stop GSM interference. Soldered by hand under a magnifyer.

Erik, How much noise is being produced by the LCD refresh? Are you able to run tests with it against the PCB and unfolded out to the side away from the SMA connectors? Can you disable the LCD routines

Best thing to do is open an issue on cho45's github repo:? https://github.com/cho45/NanoVNA-Web-Client BTW, I see the same security message.

Whenever I start https://cho45.stfuawsc.com/NanoVNA/ from within Chrome browser I get a short message at the bottom flashing up with message "Security error: must be handling a user gesture to show a

Using the console command "sample" it is possible to measure the pure reference, refl and thru signal strength. First picture shows the change over frequency of the reference signals (only look at the

test jigs added to Wiki Application Notes /g/nanovna-users/wiki/Application-Notes

I have made a test jig for my VNA based on a ZIF socket. I always measure with the ZIF socket closed, even if nothing is locked into it. A short is literally a tiny piece of wire a couple of mm long.

When using the nanoVNA at frequencies above 300MHz it switches to harmonics mode First attached picture shows the harmonics till 1600MHz of the SI5351 output when set at 100MHz. The 9th harmonic is at

Have a look here: https://en.wikipedia.org/wiki/USB-C#USB-C_receptacle_pin_usage_in_different_modes You need to attach 5.1K resistors to ground from cc1 and cc2. Scroll up the webpage to see the pins

can anyone show the circuit and photo where this 5.1k resistor should be installed. Is it possible to install it on NanoVNA-H pcb?
