One of the most helpful debugging aids is a clear picture of what’s occurring at a given point of failure. In the case of power instruments, this clarity can come from a current profile of a failing or alarming power supply. A current profile shows the measured behavior of the loads on a device, which makes it an important tool for identifying major current draws and spikes. With this information, test engineers can correlate on-tester device performance with the  designer’s expectations. This is true both for a big-picture view of the entire program and for a closer look at a pattern. This presentation is a companion guide to a Visual Basic class module that serves as a tool for collecting current and voltage profiles. This tool can be used to create a profile using any DCVI or DCVS instrument, such as the UVI80 or the UVS256, and can be imported into IG-XL test programs, adding code wrappers around the code to be profile. The class then stitches the collected profiles together and outputs a single profile of all wrapped sections of the test program, as well as optional individual profiles. This presentation will demonstrate how to use the tool, as well as best practices and useful tips.
