Using some generous amplification after the 2GHz filter the nanoVNA performance for S21 measurements is getting to a usable level. Attached S21 of a 2GHz cavity filter. It proves the SA612 has a lot

USB power is very noisy. Hugen79 designed the power part of nanoVNA different from edy555 Hugen79 uses the output of the IP5303 for 5 volt where edy555 uses the USB power. Did not check noise on

The xc6206 is terrible in transient response. Max input voltage is 6 volt so I use only 5 volt from linear regulator. The SA612 can have up to 8 volt but no big gain in performance

Yes.

May be the compilation problem caused by the flash usage limit, I have re-compiled after removing the sin/cos table in my firmware, now it can connect to the web interface normally.

Hi Rune ,thanks for your attention. the feature of recalling CALIBRATION file changing the settings of nanovna is usaul on vna I used at works for some year. The calibration is valid if you don't

Daniel, can you add a picture? Sma female on a board, or just a couple of short wires to a female? Jim, KA6TPR

I understand that there is a 4.3 inch version available. Has anyone purchased one? If so, I am in the US. Where is a reliable source to purchase one?

I got one like this https://www.ebay.com/itm/202403566060/ -- it has the advantage of skinny profile, display on big screen; the disadvantage of latency, you better move pretty slow to solder smt

Well, it's actually an itty-bitty 2-port VNA that, within its specs, provides both reflected and through measurements of RF circuits. So, for they typical ham, mostly antennas, and maybe filters.

Hi Bryan, thanks - I figured it was something like that, but it's nice to have it confirmed :-) With your description of how you did your calibration, I'm sure more people will be using these fields -

Rune, I just figured out what is causing the crash I referenced above. If a user leaves one of the text boxes in the "Calibration settings" area blank, no number at all, nanoVNA-Saver will immediately

Jeff got me going, the driver was not installed. Now to get rid of the Smith chart overlay. BTW, the R and j do come up fine on the Saver, Thanks Rune. Mel, K6KBE -- Mel, K6KBE

Hello Mel, I assume your NanoVNA is plugged in, turned on(!), and that you have tried pressing the rescan button? Assuming you are running Windows, you may need a driver installed for your system to

Hi Erik - Can TAPR VNA save those nanoVNA absolute values to files?

Rune, Good Day, First time user or want to be, hi. 0.1.3 is downloaded and comes up fine, but does not present a COM port number? What is the best way to approach this? Thanks, Mel, K6KBE

KV5R, that's great to hear! :D I try what I can to make it scaleable, but I don't personally have a high-DPI monitor (nor serious vision issues - yet), so I don't have many opportunities to test it. I
