The 32-channel PCI-24DSI32 analog input board provides high-density 24-bit analog input resources on a standard PCI expansion board. Optimized for flexibility and performance, the board is ideal for a wide variety of applications, ranging from simple precision voltage measurements, to the analysis of complex audio signals and waveforms.

32 delta-sigma analog input channels are organized into four simultaneously-clocked groups, three of which can be independently enabled or disabled. Multiple boards can be synchronized and phase-locked. Input bandwidth is from DC to 80kHz. Sample rates are adjustable from 2KSPS to 200KSPS, and the input range is software selectable as ±2.5V, ±5V or ±10V. Internal autocalibration networks permit on-demand calibration to be performed without removing the board from the system.

An optional configuration provides four independent internal rate generators, each of which can be assigned to any or all of the four channel groups.
