Hi Oristo
In the help file search in index for "trace types" there all the various and very many trace types are described also custom traces. The trick is to double click on any trace type name e.g. Smith on the lower line, and that mean any of the trace name, and the page come up with all the trace settings, and in the six wide prompt line you decided what you want to have displayed form a long drop down list e.g. dB Smith, phase and so on. In the slim prompt line you decide to what the representation just chosen must belong to, from another long drop down list S21, S11, S12, S22 and so on, and here you find the 6 custom traces. Notice if using subexpressions all 6 custom traces share these subexpression, but the top Expression line are fully individual, and in most cases you can hold the entire expression in that line.
Each custom trace can be given a Caption name, which is shown along the custom traces in the lower trace line. Here is a refinement for all traces as a right click on the trace name, e.g. the custom trace caption name and on other traces e.g. S11, you get the option to save to s1p.
For a custom trace to open the trace settings window to e.g. change color, you mist double click on the trace representation e.g. dB, to the right for the caption name. If you double click on the caption name the Custom trace is opened.
There are many other feature by right clicking around.
If the help file will not open as an old fashion Windows help file, I have a little tool which in window 10 open up for the chm files.
Kind regards
Kurt

Emne: [nanovna-users] VNWA software #calibration

If you have calibration data as impedance and delay, but want S11 s1p format, then VNWA software can generate it, according to Kurt Poulsen.

in the VNWA software you simply open a custom trace

I did not expect this "simply" to be so tricky. It appears that VNWA documentation >>never explains<< how to open a custom trace window.

Help has a section about what to do when already in custom sweep window, but getting there may be something that lucky folks are born already knowing...

Also, Frequency Range, under Settings, >>does not set Start and Stop<<, only Linear vs Log vs Listed...?

I guess this software may discourage many from purchasing the supported hardware.

The answers:
* right-click mouse button in the main window and select Trace Options,
which launches a dialog box titled 'Display Settings'
Custom is selected by scrolling down in small box next to color sample for Trace 1-6

* left double-click near Start or Stop frequencies will launch 'Input' dialog box
to set those frequency values. Sweep Mode is also selected here,
making Frequency Range option in main window Settings less than useful.

in the Expression line write s_load or s_open or s_short or
s_thrumatch or s_thru then the trace is shown according for the custom
trace to be shown as you like in Smith, dB of what ever representation
then to save directly as s1p file by a right click on the trace and use the "Export to s1p file" function.

Well, right-click on trace launches another dialog box, but no options for saving it
