Automate PCB System-Level Power Tests

Power validation and firmware engineers need to characterize and validate power consumption over a variety of operating states such as sleep, idle, and transmit. Investing in an automated test approach eliminates repetitious manual steps and improves repeatability. Key requirements include:


  • A measurement capability that scales from minimally powered sleep states to transient inrush currents

  • Sufficient measurement points to validate and verify power consumption across all power rails and subsystems

  • Data-logging and file formats that work with preferred analysis tools

  • ​A workflow to manage frequent— sometimes daily—test requests from firmware builds

PCB Power Characterization and Performance Test Solution

  • FlexLoggerTM application software for managing channel configuration, data logging with a real-time UI, alarming, and exporting data to Excel without programming

  • PXI system hardware with a PXIe-4309 32-chanel PXI analog input module for high-speed voltage measurements and flexible resolution (current measurement using shunt resistor)

  • CompactDAQ systems with an NI-9220 voltage input module for lower-cost systems that connect to a PC over USB or Ethernet

  • ​Interfacing with external applications (such as LabVIEW or Python) to remotely control data logging

Solution Advantages

“FlexLogger makes it easier to troubleshoot and verify that the raw data from different sensors is correct before I start my test. This helps shorten test development by saving time typically wasted on redoing configurations.”

—Andy Tarman, Lab Test Engineer, CNH Industrial
