The design can then produce bad data output, function intermittently, or not function at all, displaying false triggering, ringing, overshoot, or undershoot, or exhibit setup and hold time problems. A design has good signal integrity if its signals arrive at the required time, duration, and voltage. Likewise, manufacturing engineers will find that the ability to test several parameters with a single test can speed throughput on a manufacturing line. Instead of making four or five individual measurements such as Vmax, Vmin, period, risetime, and falltime, a single user-defined mask with acceptable tolerances can test for all of these parameters in a single test. Faster, more accurate testing, whether in a communication compliance test or on a manufacturing line, ensures greater confidence in equipment operation and, ultimately, greater customer satisfaction.
Cost savings stem primarily from quicker tests.
Cost savings also result from the ability of an automated test system to store test results over a long period of time, using the stored data to reveal long-term trends in performance. This information may help designers improve their products and maintenance engineers to prevent equipment failures. Automated testing saves time and money, and results in better documentation, helping designers and manufacturers produce, evaluate, and maintain designs, and ultimately, providing the best product to their customers.
