There are several software packages that can do a time domain simulation with your s11 data, but I'm not aware of any that can directly convert S11 to a signal. The s11 data represents a response; you will need to provide the stimulus. What software do you already have?=20 Aubrey Sparkman=20 Enterprise Engineering Signal Integrity Team=20 Dell, Inc.=20 Aubrey_Sparkman@xxxxxxxx=20 (512) 723-3592=20 "A Measurement for every Model and a Model for every Measurement.
