To complement its new Piranha HS 12k 90-kHz linescan camera, Dalsa has launched the Xcelera-HS PX8 frame grabber. This half-length PCIe-based frame grabber is equipped with an HSLink camera interface that achieves an image-acquisition bandwidth of 1.5 Gbytes/s and host-transfer bandwidth of 2 Gbytes/s over multiple-lane PCIe implementations.

The PCIe x8 interface of the Xcelera-HS PX8 is a point-to-point host interface that allows simultaneous image acquisition and transfer involving little intervention from the host CPU. Designed with the requirements of machine-vision OEMs in mind, the Xcelera-HS PX8 combines its HSLink camera interface with onboard preprocessing functions, such as shading correction and Bayer decoding. HSLink offers scalable bandwidth from 300 Mbytes/s to 6000 Mbytes/s and supports 1x to 20x configurations.

In addition, the Xcelera-HS PX8 furnishes a dedicated communications channel that accommodates data rates of up to 300 Mbytes/s and provides built-in support for data forwarding for distributed image processing. The frame grabber works with 32-bit and 64-bit versions of Windows and is compatible with Dalsa's Sapera Essential machine-vision toolkit. The software bundles board-level acquisition and control with over 400 image-processing functions. The Sapera Essential standard processing tool run-time license is offered at no additional charge when combined with the Xcelera-HS PX8 frame grabber.
