In 2018, we delivered a presentation about different threshold test methods on the ETS-800 platform. With the upgraded HRM instruments, UPD64, APU32A and MST version, there are more highly efficient choices. This presentation will summarize newly available test methods utilizing the new features of these instruments. Additionally, we’ll discuss a code library as .h/.cpp files which combines different threshold test methods into a single test function so that a user can configure or switch them easily. It supports various instrument combinations and debug display, making our development easier and more flexible. Users can save time developing and debugging manual code after a one-time study, and leverage it in future projects to speed up test development.
