    PULSE Vehicle Pass‐by Test Systems – Installation Manual Fig.1.1 shows an overview of a pass-by test system. The typical configuration is a multi- vehicle configuration using both the Ground Station and Vehicle Station to acquire and measure both pass-by and in-vehicle data. On the Ground Station, PULSE measures all acoustic channels, speed measurements and triggering signals.

  • Page 9: How To Use This Manual

    CHAPTER 1 Introduction 1.2.1 Multiple Vehicle Measurements It may be necessary to let several vehicle exterior noise tests run in parallel. In this case, a single Ground Station acquires the necessary acoustic and triggering reference data for all of the vehicles and the relevant run data is merged with the Vehicle Station for each specific vehicle.
