National Instruments reveals the PXIe-1435, a PXI frame grabber that acquires from all Camera Link camera configurations to include 10-tap extended-full, with up to 850MB/s of throughput targeting automated test applications in industries such as consumer electronics, automotive and semiconductor.

With this product, NI says engineers can power cameras through Power over Camera Link (PoCL)-enabled cables to eliminate the need for additional wires in deployment environments.

Further, the frame grabber offers 512MB of DDR2 on-board acquisition memory for added reliability in transferring large images without fear of data overflow. On-board digital I/O includes four bidirectional transistor-transistor logic (TTL), two opto-isolated inputs and one quadrature encoder for triggering and communicating inspection results with automation devices.

It also incorporates the synchronisation, timing, data streaming and processing capabilities of the PXI Express specification, and supports image processing on complementary field-programmable gate array (FPGA) boards to further boost system performance.

"The NI PXIe-1435 frame grabber further complements our capabilities in the PXI platform. The addition of high-performance imaging to our PXI offerings enhances our mixed-signal capabilities for high-end test systems," said Matt Friedman, NI senior product manager for the PXI platform and PXISA board member.

NI said the high throughput and low latency of the Camera Link standard make the frame grabber ideal for line-scan image sensors which engineers can use for surface inspection of large areas, including finding aesthetic and functional defects in solar panels and dead pixels in flat panel displays.

The NI PXIe-1435 frame grabber also works in many industrial applications, such as fault analysis using a stop trigger to record images before and after an event on the factory floor, and medical device applications such as analysing intricacies in movement and recording stimulus response in objects from heart valves to eye corneas.

The new module can be programmed using NI LabVIEW graphical development software, the NI Vision Development Module and NI Vision Builder for Automated Inspection protocols.
