Solution
Communication is enabled via the bus systems FlexRay, CAN and Ethernet. The device offers connectors (BNC sockets) to measuring devices (oscilloscopes, etc.) for evaluating the sensor signal quality and for analyzing the individual trigger events. The configuration of the DF measuring box is enabled via an application-specific GUI and through a CAN bus or Ethernet connection.
Result
The universal DF Measuring Box offers multiple modes:
Measuring mode: Independent acquisition of two DF sensor signals as well as processing and transferring measurement data via bus systems
Manipulation mode: Extensive manipulation of the real DF sensor signal measurements
Simulation mode: Simulation and output of DF sensor signals
Gateway: Conversion of measurement data (from sensor type A to sensor simulation of sensor type B)
