Hi David
I have noted your comment.
As far as I know many are using Linux as platform. Look in the Yahoo Forum for details and probably also in the help file which exist as pdf.
Regarding licensing I know people are invited to used the VNWA and the embedded VNWA Virtual Demo Device where you can run the software just like if you had a connected VNWA hardware. This to facilitate a potential customer to a VNWA can try it out prior a decision to purchase. The only detail is that you do not enter a license code but just carry on with the installation, so I find it hard you are right on "only licensed for use with the VNWA".
It supports also the N2PK VNA so that is another indication it is not linked to the use of the VNWA.
There might be some remark in the licensing screen during installation with a precise definition about this issue (it is a long time since I read it).
Why focus on the negative sides be positive please ?
Kind regards
Kurt

Hi David

I got permission from R&S to publish their T-Check software
and


But that was in 2012 and now you just in the VNWA software in a custom
trace right click the Expression field and the T-Check formula is
filled in. Enable a trace with linear magnitude (s parameter linear)
and with 0.01 per division (1%) and reference 1 followed by a press on
the F2 key and the VNWA performs a full 12Term measurement of T-Check.
Of course the VNWA shall in advance be SOLT calibrated and the
T-Adaptor fitted.
If a s2p file imported with full s11/s22/s21/s12 measurement The VNWA
software is totally unique (and free to use) and I have several times
"banged you on the head" to overcome you HP bias and fixation and get
on board your wonderful VNWA hardware/Software sitting collecting dust
on the shelf.

Kurt,
There are a few issues here

1) VNWA software is closed source.
2) VNWA software only runs on Windows
3) Although the VNWA software is free, the last time I looked it was only licensed for use with the VNWA. I know Tom has never pressed this, and in fact once Tom made a change that allowed me to read in S-parameters from my LCR meter, although the VNWA software doesn’t fully support the Touchstone file format. I would add the same is true of an Agilent PNA-X
????. Sonnet Lite was a free, but closed source application which has better support for Touchstone files.

As an advocate of open source software, and as someone who has a dislike for Windows, I would rather an open source solution I can run on a Unix or Linux system.

Dave
