I am trying to use my NANOVNA for the first time. I have gone through the calibration process several times. I believe the unit is calibrated, but when I turn it on I do not get the typical horizontal lines. I can turn on the four different traces and see the information about the traces at the top, but there isn’t anything ever displayed. I may have one of the menu items set up incorrectly. How do you get it to sweep? Any suggestions?

Post a picture or take a screenshot so we can see what is going on.

Go into the Scale menu and change SCALE/DIV and/or REFERENCE POSITION for each TRACE

What should I change the scale/div or the reference position to?


I appreciate your help.

I vaguely recall a post here about a week or two ago
regarding how to enable and disable scanning through the stand-alone user interface.
Somewhere in that menu tree.
Anybody remember?

Depends on FORMAT settings, but numbers on screen shot look pretty huge;
perhaps cal failed (did you first select RESET?)
or "Clearconfig 1234' from a terminal program is wanted

Here is a screen shot.

Perhaps CALIBRATION is toggled off?

Oops, replace "CALIBRATION" with "CORRECTION".
Depending on FORMAT and CHANNEL settings for each TRACE,
scans can be meaningless..

Oristo,

That was it! I toggled the “Correction” and it is working!

Thank you!

Mike

That was it!

Thanks for feedback; I was also lost there before; CORRECTION option was added by some firmware "update".
