High Speed Signal Design, Test and Analysis

Signal & Power Integrity in the Real World

We offer an affordable online solution to calculate the line impedance on printed circuit boards (PCB). The STLC online tool enables the user to precisely calculate the wave impedance of all commonly used transmission line types on PCBs by applying a powerful 2-D field solver technology. If you would like to get more information about prices & conditions or you want to sign up for a free trial period of 2 weeks for the STLC please do not hesitate to contact us directly. We will be glad to inform you.
