The 16-Bit PC104P66-16AI32SSC 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 PC104+ 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 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..
