Hi Kurt -
Thanks for the additional hints, so essential success!
double click on any trace type name on the lower line
... which for the attached VNWA main window are 'Log Mag' or 'Smith'
the page come up with all the trace settings
.. which is titled 'Display Settings', also attached
another long drop down list S21, S11, S12, S22 and so on,
and here you find the 6 custom traces.
... shown below with Custom1/Custom2/Custom3 selected for 'Smith' and 'log magnitude'
the top Expression line are fully individual...
Each custom trace can be given a Caption name
.. shown below with Expression 's_open' and Caption: 'open'
Then, by clicking any of 'short', 'open' or 'Load' words next to check boxes below plots,
not the plot lines, then a dialog box appears with an option for 'Export Trace to s1p'
There are many other feature by right clicking around.
It is IMO a crazy user interface, perhaps if all were by right click instead of some by left double-click..
Anyway, s1p files exported, then can plot in gnuplot, revealing differences between open and short logmag
