Designing Power Distribution Networks for Automated Test Equipment

January 3, 2013

The demands on power architectures designed for automated test equipment (ATE) applications have increased dramatically as these systems become more complex. Only a few years ago, many ATE systems used simple “silver box” supplies, but this is no longer a sustainable approach.

Modern ATE circuitry requires more power to operate, whilst voltage and current requirements span a wide range. At the same time, these power systems need to accurately and quickly modulate various voltage rails in order to completely characterize the performance of a device under test (DUT). The power system has therefore become a key element of ATE design.

Maurizio Salato, Director of Systems Engineering at Vicor, has written a white paper that discusses these trends and provides system-level approaches that help to achieve common design goals, such as:

  • Minimizing bills of material
  • Optimizing the thermal management system by controlling distribution losses
  • Enabling the highest degree of flexibility in test card design and configuration
  • Achieving the highest degree of system availability through design for reliability and redundancy
  • Enabling the highest level of modularity and providing the system with on-line diagnostic options
  • Minimizing EMC and EMI within the system

This white paper is invaluable for anyone developing ATE equipment, and will also be of interest to all power system designers who have to meet demanding requirements. Register below to receive a copy of Power Distribution Network Design for Automated Test Equipment.
