Keysight Technologies Test-System Development Guide Choosing Your Test System Software Architecture Application Note This application note is part of the Test-System Development Guide series, which is designed to help you quickly design a test system that produces reliable results, meets your throughput requirements, and does so within your budget. Introduction The information presented here will help you choose the direction for your software based on the application you have in mind and the amount of experience you have. We will explore the entire software development process, from gathering and documenting software requirements through design reuse considerations. The complete list of application notes for this series is available on page 19. This white paper will help you understand the tools required to design, develop and deploy the software component of your test system (see Figure 1).

Test-system software development process overview Gathering and documenting software requirements--Before gathering and documenting your software requirements, inalize your test system hardware design. Once inalized, start working with your R&D and manufacturing teams to collect the information you need to create software requirements speciications (SRS). Programming and controlling your instruments--The control of instruments is rapidly evolving from proprietary test and measurement standards to open, computer-based industry standards. This trend affects the hardware that connects the PC to the instrument as well as the software and drivers that control the instrument. Collecting and storing test data--Data collection is the science of obtaining, moving and formatting data. The integrity of your test system depends on obtaining the right data at the right time. Designing the user interface--One of the most important (and easily overlooked) aspects of test
