The UPD-64 is a mixed signal instrument which has a broad feature set and its introduction greatly improved the capability of the ETS-800 Test Platform. At this point, APEX is a well-known and highly utilized capability of the UPD; and, this paper will continue to give examples of optimizing APEX usage. Furthermore, this paper continues by highlighting other significant features that exist and can be leveraged in the planning phase of a DIB Design. Knowing these features beforehand and designing them into the DIB can enable Test Engineers to obtain more significant contributions from the instrument. This includes examples of where and when to make specific design considerations and improving positive satisfaction of requirements on both ends of the mixed signal spectrum. In summary, this paper is set upon the goal of making the instrument a more significant and broad contributor to successful designs within the ETS-800 test platform.
