DS6221 A/D Board

Fast SCALEXIO A/D Board for precise measurements

The DS6221 A/D Board provides 16 high-speed analog channels, versatile trigger capabilities, and a high-throughput streaming interface. It is an excellent choice for precise measurements, even of fast analog signal sequences.  

  • 16 differential A/D channels
  • 250 ns conversion time (4 Msps) and 16-bit resolution
  • Versatile trigger capabilities 

Application Areas 

With its accurate high-speed analog channels and versatile trigger capabilities, the DS6221 is an excellent fit for precise measurements, even of fast analog signals sequences, in various applications areas. It can be used for scenarios such as the development and testing of electric drives applications or vibration and noise cancellation applications as well as for high volume data acquisition in test bench scenarios.

I/O Functionality

The 16 analog input channels of the DS6221 are software-configurable and can be used as

  • Voltage In
  • Voltage Signal Capture

The channels are defined and configured graphically with dSPACE ConfigurationDesk.

Key Benefits

Each of the DS6221‘s 16 differential input channels has an independent A/D converter with a resolution of 16 bits and a minimum conversion time of 250 ns. Advanced configurable trigger per channel, such as on-board timers, external trigger input lines, or predefined angles of SCALEXIO’s angular processing unit, allow the precise event-based capturing of analog values and signal sequences. For comprehensive and fast data capturing the IOCNET-based streaming interface provides a continuous sample data throughput of up to 40 Msps to the real-time application1).
