Alfamation, a provider of turnkey test and measurement solutions, introduced two PXIe boards, which automate a wide range of testing tasks required on the production lines of UHD TV, computer monitor and other high-resolution displays.

Power, speed and precision combined

The continuous evolution of flat screen display technology, with increasing resolutions, deep colors and higher frame rates, is placing high demand for precise testing of complex components. The PVA-01 and PVA-04 platforms enable detailed real-time analysis of any video content transmitted via LVDS links from the chipset on the motherboard to the display. Testing rates exceeding 20 Gbit/s on UHD TVs and computer monitor mainboards are now attainable, allowing electronics manufacturers to slash testing times whilst producing top-quality end products.

Human-independent, fully automated testing delivers faster, reliable and repeatable results than the human eye, and screen size no longer plays a role. Built according to the industry-standard modular PXI Express platform, these boards greatly reduce outgoing manufacturing defects. The PVA-01 interfaces with the parallel-clock LVDS & EPI video standards, while the PVA-04 board interfaces with the One video standard.

Sophisticated and flexible image quality assessment

Both boards benefit from the company’s image processing technology, featuring real-time bit error rate, pixel error rate, PSNR analysis and frame capture to bring extreme levels of performance and compactness. Unlike the traditional pixel-by-pixel image comparison algorithm, both boards can run image quality assessment algorithms on any type of video input in real-time in any format supported by modern video imaging chipsets.

High resolution, high bandwidth simultaneous testing

The test bandwidth allows processing up to 1080p at a 240 Hz frame rate, with a 30 bit per pixel color depth or 4K Ultra-HD video at 60 Hz. However, the 8 available channels may be split or aggregated in various ways with use of up to 8 devices, each at 1080i equivalent resolution. Thanks to their full compatibility with the NI LabVIEW platform, they easily integrate into any modular automated test system providing on-board result processing and a relatively quiet bus data transfer. Also, they boast a 4x Gen2 PXIe connection that supports very high bandwidth encrypted video streaming through the PXIe bus to mass storage devices for off line analysis by enabled users to support in design validation tasks.
