If i correct remember this not awaible in all fw But now possible quick change refrence and scale position for curent selected trace see attached image

Hello Dislord. Thank you very much for the continuing excellent support of the VNAs. I have a question: the numerical displays for changing (for instance) the 'reference position' do not have the

Not that you were, but in case you were wondering, you are amazing! Thank you from all the users for your tireless work in making this happen! 73, Willie N1JBJ

I add xtal autodetect (for more easy support vs xtal and no), but in some rare cases LSE mode enabled if no xtal on device. Need remove battery and reset this state. But better instal it for more

This may be of interest for those testing balanced lines with a VNA for HF applications. From the 2019 ARRL Handbook Roger

I agree with you. I have been doing some tests on a 38.75 foot piece of 300 ohm twin lead with the intent of creating a 1/4 wavelength stub. I used a signal generator with a fast pulse and a digital

Roger, Try setting the time using OneOfEleven's Nanovna-App. It's under Settings. I had a similar issue with my H4 with 1.0.44 through 1.0.47 FW. The app uses the binary mode to set the time.? Note

I own a -H4 that does not have the Xtal installed. The time under Version says 2000/01/01 00:00:07 (LSE) I have tried to use the commands above to set the time and they appear to be accepted without

Chris, The only time you should use the Reset button in the Calibration menu is immediately prior to performing a calibration. Reset clears calibration entries in RAM so if you use it immediately

Looks like it is saved in the calibration settings not in the configuration settings.? That is what I had wrong.? Also, I want to confirm that you have to reset a channel before you save to it.?

It occurs to me that it might be easier to characterize a longer piece of line (which allows one to work at lower frequencies and have fewer capacitance problems) and then cut the desired

I have version 1.0.45 Build Jan 30 2021

I absolutely agree I was talking about ideal lines... and ideal VNAs. One must always take these things into account. Thanks for keeping me honest....

Hi Chris, Please let us know the model/version of Nano you have and the version of firmware from the Config>Version screen. What you're doing should work as that is how I configure my unit. Thanks

I want to save Trace 3 to do SWR instead of phase. Even though I save it in a profile and the general settings. It always pops back to phase. How do I make these changes permanent? Also, when I want

Ward, What you say is true for theoretical transmission lines with no attenuation. A physical TL has attenuation and you don't get exactly 0 ohms at the end of a open 1/4 wavelength transmission line

or open.? Either way, you get mag s11 = 1 when it's a 1/2 wavelength long. However, the OP wanted 1/4 wavelength. So you could use the fact that 1/4 wave transforms the impedance at the far end. So

To measure 1/2 wave you could simply short the far end. Sweep the frequency. When s11 is -1 (impedance is zero) you're at the 1/2 wavelength frequency (or a multiple thereof, start the sweep very
