DS6241 D/A Board

Multi-channel D/A board

The DS6241 D/A Board provides 20 accurate analog out channels, with dedicated ground sense line and versatile synchronization mechanisms, trigger capabilities, and a high-throughput streaming interface. It can be used for rapid control prototyping (RCP) as well as hardware-in-the-loop (HIL) testing applications.

With its accurate analog out channels, the DS6241 can be used for rapid control prototyping (RCP) as well as hardware-in-the-loop (HIL) testing applications. During the development of ECU functions, it works as an analog signal generator for actuator control, e.g., for noise cancellation. In test scenarios, it generates signals for sensor simulation.

Key Benefits

Each of the 20 output channels included in the DS6241 comes with a dedicated ground sense line and provides a resolution of 16 bits. The board offers a flexible simulation of sensor signals and a versatile synchronization mechanism, e.g., a configurable trigger function for four channels and synchronization with SCALEXIO's angular processing unit. 

I/O Functionality

The 20 analog channels of the DS6241 are software-configurable and can be used as

  • Voltage Out
  • Wavetable Voltage Out
  • Waveform Voltage Out
  • Angular Wavetable Voltage Out

The channels are defined and configured graphically with dSPACE ConfigurationDesk.
