The 16-Bit PMC66-16AI32SSC analog input board samples and digitizes up to 32 input channels simultaneously at rates up to 200,000 samples per second for each channel. Each input channel contains a dedicated 16-Bit sampling ADC, and the resulting sampled data is available to the PCI bus through a 1-MByte FIFO buffer. The 32-Bit local data path supports full D32 local-bus data packing. Throughput capacity is further enhanced with 66MHz PCI support. All operational parameters are software configurable.

Inputs can be sampled in groups of 2, 4, 16 or 32 channels; or any contiguous channel group can be selected for sampling. The sample clock can be generated from an internal rate generator, or by software or external hardware. Input ranges are software-selectable as ±2.5V, ±1.25V or ±0.625V.

An on-demand autocalibration feature determines offset and gain correction values for each input channel, and applies the corrections subsequently during acquisition. A selftest switching network routes calibration reference signals to each channel through internal selftest switches, and permits board integrity to be verified by the host..
