  • TransmissionLine – This free application runs on Windows™ platforms. The program simulates a transmission line (PROFIBUS cable) and shows the voltage and current along the cable as signals pass from one end to the other. Terminations can be varied at each end to show the reflections that occur when the termination resistance does not match the characteristic impedance of the cable. Please note that this application can be used by individuals, companies and educational institutes. However, the software is owned by Verwer Training & Consultancy Ltd. and is protected by copyright © 2008-2015.
