The 18-Bit PC104P66-18AI64SSC750K analog input board samples and digitizes 64 input channels simultaneously at rates up to 750,000 samples per second for each channel.
Each input channel contains a dedicated 18-Bit sampling ADC, and the resulting 18-bit sampled data is available to the PC104+ bus through a 256 K-Sample FIFO buffer.Throughput capacity is further enhanced with 66MHz PC104+ support and increased local clocking frequency. All operational parameters are software configurable.
Inputs can be sampled in groups of 1, 2, 4, 8, 16, 32 or 64 channels; or software can select a first and last channel to be acquired. 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, and 0 to +10V, or optionally as ±5V, ±2.5V, 0 to +10V, and 0 to +5V .
An on-demand autocalibration feature determines offset and gain correction values for each input channel, and applies the corrections digitally 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.
