LA9000 S-Parameter Analysis

When you need to compare s-parameter data from a range of sources, or simply need to look at a suite of simulations against each other the LA9000 provides an easy to use graphical display of S-parameters from any source of Touchstone™ files.

The LA9000 is at its best when connected with the Si9000e insertion loss field solver where the “projects” option can auto export a bundled suite of s-parameter data along with the associated mechanical and electrical properties for the transmission lines being simulated. This can for example allow you to visualise differences in insertion loss for groups of structures which are geometrically identical and yet deploy different performance base materials.

Likewise if you have access to Touchstone data from a measurement system the LA9000 can take this and display alongside the simulated data and associated transmission line structure information from Si9000e.

Using Speedstack/Si Projects

If you use Speedstack you can also export a project to Si9000e and explore the transmission line behaviour of, for example, a 50 Ohm trace on an outer or embedded or inner layer, Si9000e is a powerful tool for transmission line simulation, and for detailed analysis of a single line at a time. Speedstack can easily export a project for processing into S-parameters by the Si9000e and then onward in a single click to the LA9000.

Using the projects capability of the Si9000e in conjunction with the LA9000 allows you to compare groups of related structures in seconds.

PCB technologists adding LA9000 to their Speedstack Si installations can benefit from the Speedstack Online libraries to process simulations of the same PCB when built with base materials from different suppliers.

Contact Polarcare@polarinstruments.com to arrange an evaluation of this new product which is in beta release phase at the moment. LA9000 operates both as a standalone product allowing you to drag and drop Touchstone™ files, as well as with Speedstack Si and Si9000e.

The active link between Si9000e and LA9000(beta) is available from Si9000e Version 19:05 onwards.
