The 16-Bit PC104P66-16AI64SSC analog input board samples and digitizes 64 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 16-bit 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 PC104+ support and increased local clocking frequency. All operational parameters are software configurable.
Inputs can be sampled in groups of 2, 4, 8, 16, 32 or 64 channels; or any single channel can be sampled continuously. The sample clock can be generated from an internal rate generator, or by software or external hardware. Input ranges are software-selectable as ±10V, ±5V or ±2.5V.
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..
