[SI-LIST] mixed mode differential s-parameter processing and display software

All,

First of all, we at Teraspeed® Consulting and Teraspeed® Labs have no 
financial interest in the following product, however from time to time 
list members have asked about software capable of processing 
S-parameters and displaying differential mixed-mode s-parameters.  A 
little company in the UK called Ark RF systems has some S-parameter 
capture and analysis software that now includes mixed-mode conversions 
and display for any multiple of 4 single ended ports in a Touchstone 
file.. 

We've been using their software for 2-port VNA control and S-parameter 
display and processing for years and asked them to include mixed-mode 
conversions into their product.  In about a week, Andy had integrated 
the functionality in their latest release. For those of you who are true 
mixed-mode geeks, this new addition to their product is pretty darn 
cool.  They have an evaluation version of the program that shows most of 
the features available, but unfortunatly not the mixed-mode s-parameter 
conversions and display.  But, the actual software is really inexpensive 
if you do not need to control a VNA.  With it you can view and perform 
some post processing on Touchsone S-parameter files of pretty much any 
size and number of ports up to 98.  If you do have a 2-port VNA, then 
their interface provides seamless control, along with the capability of 
turning a 2-port VNA into an N-port S-parameter extraction machine.  We 
commonly use ours for 4-port measurements, and it is fully capable of 
performing extractions of as large a number of ports as your patience 
and calibration will allow.

Here's a link  to the company and a data sheet on the software.
