Price request Datasheet

The 18-Bit CPCI66-18AI64SSC750K 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 cPCI bus through a 256 K-Sample FIFO buffer.Throughput capacity is further enhanced with 66MHz cPCI 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.
