Product Description
The PCI32ADC24 is a sensor interface card which allows server class PCs to be deployed in a wide variety of acoustic signal processing applications, including sonar beam forming, vibration analysis, geophysics, and other test and measurement applications. This full length PCI Express slot card accepts 32 analog input channels, which it converts to digital data with 24-bit resolution, at sample rates up to 216 kHz. The GB104 design includes precise synchronization between multiple cards; systems can be expanded to support hundreds of channels. Minimal analog signal conditioning is used in the design: only adjustable gain and two pole anti-alias filtering. All other processing is performed using the on board FPGA resources. The PCI32ADC24 can be used as a direct replacement of ICS-610 data acquisition board.
