PCI-24DSI12 : 12-Channel 24-Bit Delta-Sigma PCI Analogue Input Board

Low noise performance, 24-bit resolution, low phase distortion and multi-board synchronization make the General Standards PCI-24DSI12 analogue input PCI format board ideal for state-of-the-art sonar and noise monitoring applications. The 12-channel PCI-24DSI12 analog input board provides a high-density 24-bit analog input resources on a standard PCI expansion board.

The PCI-24DSI12 is optimised for those applications requiring both flexibility and high 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 the 12 delta-sigma analogue input channels can be controlled by any one of two independent sample clocks and multiple channels can be harmonically locked together. A/D conversions on multiple boards can be synchronized and phase-locked. The 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 periodic calibration to be performed without removing the board from the system.

Software support is available for the following operating systems:

• Windows 2000
• Windows NT 4.0
• Windows XP
• Windows ME
• Windows 98ME
• Linux 2.2
• Linux 2.4
• LabView
• VxWorks
• QNX
• Linux 2.6
• Please call Sarsen Technology on +44 1672 511166 for details of support on other operating systems

Each of twelve analogue input channels contains a lowpass image filter and a delta-sigma A/D converter that provides digital antialias 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 2KSPS to 200KSPS. 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.

Extended temperature range versions are available for all General Standards Corporation products. Please contact Sarsen Technology for full details of the cables, adapter boards, break-out boards and other accessories available for the PCI-24DSI12.
