Case Studies

  • DSA 2.9 In-Vehicle Data Logger
    Signal.X created an in-vehicle data logging solution based on the existing DSA 2.9 NVH analyzer platform, and delivered a turnkey combination of hardware and software focused on reliability and ease of use.
  • Developing a High-Volume Automated Production Test With CompactRIO
    Signal.X used CompactRIO to build a system that powers a programmable automation controller (PAC) to execute many functions that, in the past, would have required several different controllers or PLCs.
  • Designing Effective Metrics for Automated NVH Test
    Production line noise, vibration, and harshness (NVH) pass/fail testing requires a flexible metric design environment, robust data collection, easy retrieval, and automated postprocessing tools to satisfy a typical manufacturing setting. See how you can use the Signal.X MajX System to implement high-volume production NVH tests of products such as engines, axles, and electric vehicle motors.
  • Measuring Seat Adjuster Sound Quality in an Automotive Production Line
    Developing a cost-effective solution for production line testing of automotive seating products that can provide objective metrics for suggesting corrective actions to be combined with standardized sound quality metrics so subjective human impressions can be incorporated into the overall acceptability criteria.

Turn Key Systems

  • Shield
    Design and deploy NVH metrics for use in Machine Condition Monitoring (MCM) applications, Automated Production NVH test, and Laboratory test stand automation. Metric formulations developed in Shield are deployed using our MajX NVH Controller which operates at the direction of your test stand control system.
  • Trove
    Trove automates the archival and reporting of the large quantities of data that can be generated during autonomous data collection using the MajX NVH Controller.


LabVIEW Tools Network

  • Scout TDMS Editor
    The Signal.X Technologies Scout TDMS Editor is a free and easy-to-use tool for viewing Technical Data Management Streaming (TDMS) data files and editing property values.
  • DSA 2.9
    DSA 2.9 is an easy-to-use NVH measurement and analysis tool designed to access to the rich feature set available in the National Instruments Sound & Vibration toolset. While offering flexibility and power, MajX-DSA is designed to simplify the user experience making it ideal for those who want to get to the data fast with minimal exposure to complex configuration procedures.


  • Shield: A Platform for Automated NVH Assessment
    Automate the assessment of quality and functional performance using dynamic data and metric-based decision making. Use Shield in production end-of-line systems and laboratory automation.
