• Available on adapters for alternate form factors, including PCI, cPCI and PC104-Plus, as well as PCI-Express, PCIX and cPCIX

Specifications

The General Standards 16-channel 24DSI16WRC analog input module provides high-density 24-bit analog input resources on a standard single-width PMC. 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.

Each of 16 analog input channels contains a lowpass image filter, and a delta-sigma A/D converter that provides inherent antialias suppression and sharp cutoff lowpass filtering. An internal voltage reference can be applied to 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 lowpass analog filter reject those interference signals that fall within the harmonic images of the digital filter.

An internal sample-rate generator is adjustable over a 2:1 frequency range, and is divided down within the local controller to provide individual channel sample rates from 0.4KSPS to 105KSPS in the high-speed clocking mode, or from 0.2KSPS to 52KSPS in high-resolution and low-power modes. Conversion data from all active channels is transferred to the PCI bus through a 256K-sample data buffer that is supported by two DMA channels. Multiple channels can be synchronized to perform sampling in "lockstep", either by a software command, or by external hardware sync and clock input signals.
