Jim, What benefit does this approach offer over using a DPDT/transfer switch? Is this just a cost concern? I note for example that a transfer switch approach would solve concurrent access to multiple

I've run two instances of NanoVNA-Saver and it seems to work ok - here's a picture of two.? I scaled the image down so it's a reasonable size. I find that setting the font to 12 point makes it more

hello there is way to connect to PC I got 76 years and got some problem with sight, *Sent:* Wednesday, October 13, 2021 at 9:12 PM *From:* "Jim Lux" <jim@...> *To:* [email protected]

yes - here's some examples (a 21.4 MHz BPF and a 10dB pad)

I succefully got it ... MNI THANKS Peter

The DUT position is on the midle of the T ? *Sent:* Wednesday, October 13, 2021 at 4:56 PM *From:* "Francesco" <realfran@...> *To:* [email protected] *Subject:* Re: [nanovna-users] two

Hello Jim, I appreciate your availability to teaching and explaining your experiments and test with good manners, this is characteristic of one gentlemen. Thank you. The VNA is one instrument not in

Have there been any comparison measurements made against a modern impedance analyzer or against an old Q meter (BRC or YHP)? It was a long time before modern instruments could agree with the old Q

You have to turn off the sweep on one while making measurements on the other. Otherwise there's interference, which shows up in the S21 trace. Sort of like if you have a transfer switch (or swap

How is the sweep synchronized in both of these devices? Unless it doesn't have to be synchronized, but it seems to me that it does.

My first experiment was just using Ts.? This works, but doesn't present a 50ohm impedance to the device under test (DUT), rather it presents 25 ohms (because you've got two 50 ohm terminations in

Hello, how connect two nanoVNA linked for a full two-port setup, I lost some pictures .

Go to message #25030 from Brian Beezly and the link is there. And Thank You Brian for "coil"

Where COIL v. 4.2.2 is available for dowload ??? Thanks - Peter

I think the original question was how to run Brian Beezley's COIL program (which is Windows/DOS) that is *non-trivial* on a Mac - the *easiest* way is to fire up a virtual machine of some sort, but

Andrew, I’m sorry but I can’t remember. It must have been fairly easy or I wouldn’t have managed it. I do know that I access it from the terminal by typing; cd nanovna-saver (ENTER) NanoVNASaver

Yes, thanks, the image looks good. I too have googled Windows apps on a Mac, and they require strange things I have never heard of. I don’t know what Wine is, for example. Nor Python. I followed

Sorry, Andy. I know nothing about Macs. But googling yields many results for running Windows software on a Mac, including a version of Wine. Here is a screenshot of an actual Litz coil for a crystal

How did you get it loaded and working?
