The 64-channel PCIe-24DSI64C200K analog input module provides high-density 24-bit analog input resources on a standard PCI Express module. Optimized for flexibility and performance, the board is ideal for a wide variety of applications, ranging from precision voltage measurements, to the analysis of complex acoustic signals and waveforms.

Each of 64 analog input channels contains a delta-sigma A/D converter that provides inherent antialias suppression and sharp-cutoff digital lowpass filtering. The digital filter can be software-configured either as a fast low-latency filter, or as a wideband low-ripple sharp-cutoff filter for maximum antialiasing.
An internal voltage reference can be applied through all channels to support selftest operations and autocalibration. Gain and offset trimming is performed by applying correction values that are determined during on-demand autocalibration. A linear-phase digital antialiasing filter rejects out-of-band signals, and a simple lowpass analog filter reject those interference signals that fall within the harmonic images of the digital filter.

ADC clocking is obtained either from an external hardware source, or from an internal sample-rate generator. The internal generator is adjustable over a 2:1 frequency range, and is divided down within the local controller to provide sample rates from 1.0 KSPS to 250 KSPS. Conversion data is transferred to the PCI Express bus through a 256 K-sample data buffer that is supported by two DMA channels. Multiple boards can be synchronized to perform simultaneous sampling with external sync and clock connections. Burst acquisition is supported.
