Tektronix, Inc. announced a new Serial Data Link Analysis Visualizer software package (SDLA Visualizer) for Tektronix performance oscilloscopes including the DPO/DSA/MSO70000 Series. Designers working on next generation high-speed serial standards can use SDLA Visualizer to specify their link, de-embed any components from the measurement path, simulate virtual link components, apply equalization and take measurements at multiple points on the transmission line in a serial data system, module or chipset.
The SDLA Visualizer enables designers to bridge the gap between modeling behavior and actual signal integrity performance. This in turn reduces design cycle time and speeds up decision making on critical design projects.
SDLA Visualizer provides complete 4-port modeling and takes into account transmitter output impedance, scope and receiver input impedance, and channel and fixture impedance to provide the truest representation of the signal possible. This is accomplished by accounting for reflections, insertion loss and cross coupling terms of each element in the link. It also enables the user to validate and debug S-parameters on individual link elements on demand, saving the user time and providing element by element or visibility at any test point in the link.
SDLA makes validating the link model easier with a complete set of plots including frequency response, phase response, and plots of all 16 S-parameters. Adding to its usability, SDLA provides a single common user interface to define all link components while giving the user the flexibility to define multiple test points instead of having to create a different link model for each test point. SDLA Visualizer coupled with DPOJET Jitter and Eye Analysis software allows the user to validate the eye and jitter results at multiple test points simultaneously, providing confidence that the model is configured correctly.
