Description
  • The 16-Bit cPCI66-16HSDI4AO4 analog I/O module uses sigma-delta A/D conversion to sample and digitize four input channels simultaneously at rates up to 1.0 million samples per second for each channel. The resulting 16-bit sampled data is available to the PCI bus through a 256K-Sample FIFO buffer. Sampling can be controlled in groups of 1 through 4 channels, and the sample clock can be generated from an internal rate generator, or through software, or by external hardware. Both burst and continuous sampling modes are supported. Input ranges are software-selectable as ±10V, ±5V, or ±2.5V.

    Four analog output channels provide software-selected output ranges of ±2.5V, ±5V or ±10V, independent of the selected analog input range. The outputs are accessed either directly through dedicated control registers, or through a 256K-Sample FIFO buffer for waveform generation. Arbitrary waveform and periodic function generation is supported, as well as realtime function concatenation.

    A 16-Bit bidirectional digital port can be configured as two independent byte-wide ports.
