There are many devices running on ETS-300, ETS-364 or ETS-88 that may have much better economics when converted to an ETS-800 solution. The advantages of the ETS-800 goes well beyond just giving the user the ability to scale to higher site counts. This presentation will cover some topics and share tips that can be helpful when making this transition. We will discuss items such as sample configurations, including suggested use of APEx. This will be demonstrated with detailed config block diagrams that show all tester resources mapped to device pins and DIB hardware. This will cover tester resource assignment, and planning of resource sharing. This will include a comparison of tester resources between platforms, and how to best utilize the latest instruments to provide the best cost of test. There will be a focus on hardware design, to make the best use of the Multi-sector technology built into ETS-800 MST.
