24DSI64C200K

Overview

24-Bit, 64-Channel, 250KSPS, PCI-Express Module

The 64-channel 24DSI64C200K analog input module from General Standards provides high-density 24-bit analog input resources on a standard PCI Express module.

Optimised 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.

Ordering information

Ordering Information:
Specify the basic product model number followed by an option suffix “-A-B-C-D-E”, as indicated below. For example, model number PCIe-24DSI64C200K-64-10V-500K-SRF-0 describes a PCI Express module with 64 input channels, ±10V input range, standard 500 kHz low-pass image filter, standard 32.768 MHz reference frequency, and no custom features.

For industrial (extended) temperature operation, add “-I” at the end of the model number.
