I use a crystal test fixture that I built for the Poor Ham Scalar Network Analyzer (PHSNA) and I used it very much with good success with the nanoVNA also. It consist on two 50 to 12,5 Ohm broadband

Hi tuckvk3cca I had that problem before; I set up the smith chart on the left hand side. I looks to me like the square shape of the smith chart does not line up properly with the right hand edge, so

Hi Truck, there may be a problem with the operating system, such as the screen size you choose or the frame rate you choose. If this helps, check to see if the

My guess is the 33 nF is 33 pF, a typo. Transfer to a series may give 39 pF and hence the double loaded C is 19 pF. Again the fixture is specific and not generic test set.

Wow, Gigaparts is carrying the new one? Is that the actual Hugen built unit?? or just a good knockoff....? or? Thanks -- Regards, Chris

I want to compliment whomever created the NanoVNA TDR firmware additions. I started with the the NanoVNA-Saver TDR and became confused because it does not work the way that I remembered a TDR should

It appears that this fixture is specific to the crystal under investigation. The fixture is providing a total load R of 25 ohms series from each side. Is possible if you transform the shunt C to its

Hi Bill Sound as an interesting project. I visited the gitbug and found not much description about the text fixture. I suppose you found it via KiCad. It must be a bug it will not work up 150MHz as

Yeah, that cap seems awfully big to me, too.? I recently built a similar fixture for crystal testing, and I didn't use any capacitor in it.

Try an earlier version of Nanovna Saver.

I am building a test fixture for use with my nano-VNA. The primary purpose is to test/characterize a group of crystals for use in a crystal ladder filter in a couple of receiver projects I am using to

Installed Nanovna Saver on my Win 7, 32 bit machine. It starts and then the whole screen shakes . Unusable. On my win 10 machine it runs ok. Any fixes?

Hi Ian As you describe it look like it is the S parameter the output consist of, as real and imag part. For the real part 0=50 ohm and 1=infinitum ohm. For the image part short = -1 and open=1

Dear All, ?I am writing a LabVIEW app to read back data from the Nano VNA. I can command the nano to sweep, no problems, using the sweep command. Reading back the data is proving harder. The command
