Low noise, 24-bit resolution, low phase distortion and multi-board synchronization make the PCIe-24DSI32 board ideal for state-of-the-art sonar and noise monitoring applications. The 32-channel PCIe-24DSI32 analog input board provides a high-density 24-bit analog input resources on a standard PCIe 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 wave-forms. Each of the 32 delta-sigma analog input channels can be can be harmonically locked together. A/D conversions on 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 auto-calibration networks permit periodic calibration to be performed without removing the board from the system.
