DS6242具有精确的模拟输出通道，可用于快速控制原型（RCP）以及硬件在环（HIL）测试应用。其10个电隔离模拟输出通道支持电压输出和电流灌入。对于电压输出，您最多可以将三个通道组合使用，以覆盖-60V至+60V的电压范围。
在ECU功能的开发过程中，DS6242能够作为执行器控制的模拟信号发生器。在测试场景中，它生成用于传感器仿真的信号。

1) Unless stated otherwise, the specifications are valid only if the dSPACE hardware is correctly connected to the power, switched on, and ready for operation.
2) Full-scale range (FSR) step, value generally depends on output load condition.
3) It depends on the voltage direction whether the current is negative or positive.
4) You cannot use current enhancement and voltage enhancement at the same time.
