Stimulus
In some sense, the beginning of a synthetic instrumentation system is the stimulus generation, and the beginning of the stimulus generation is the digital control, or DSP, driving the stimulus side. This is where the stimulus for the DUT comes from. It’s the prime mover or first cause in a stimulus-response measurement, and it’s the source of calibration for response-only measurements. The basic CCC architecture for stimulus comprises a three-block cascade: DSP control, followed by the stimulus codec (a D/A in this case), and finally the signal conditioning that interfaces to the DUT.
