Applications:

The CPCI-ADDA supports P.I.D. loop closure frame rates of up to 4 KHz per channel. The CPCI host can download gain and setpoint changes on the fly. The CPCI host can read back the current values for feedback, error, set-point, and output drive on each channel. The local DSP processor can be used for data processing such as digital filters and FFTs. The DSP can also be used as a waveform generator to drive the 16-bit DAC.
