New from NI, the PXIe-1491 digital audio and video analyser

NI's PXIe-1491 is shipped with NI Video Measurement Suite, a versatile test suite for analysing a wide variety of video standards. NI also offers add-ons such as NI AudioMASTER software, designed for in-depth audio testing including frequency response and THD, and NI Picture Quality Analysis (PQA) software. NI PQA software delivers world-class quality of experience (QoE) metrics such as peak signal-to-noise-ratio (PSNR) and structural similarity index metric (SSIM). In addition, NI PQA software enables engineers to measure lip synch, macro blocking, dropped frames, pixelation and more in real time by combining PXI Express technology with highly parallelised measurement algorithms.

The benefits of NI PXIe-1491 extend beyond at-home consumer electronics. Applications include testing of aerospace and defence systems, automobile rearview camera and infotainment systems, in-flight entertainment systems, video conferencing and professional audio/video equipment.

Charles Schroeder, Director of Marketing for Test at National Instruments, says: "The NI PXIe-1491 enables the audio/video analyser industry to think beyond the manual solutions used today. By automating the inspection process with our new, high-performance hardware and software, our customers can now guarantee the video quality of their HDMI and mobile devices with breakthrough efficiency and cost savings."

With the NI PXIe-1491, engineers can:

• Automate testing of HDMI, DVI and mobile HD devices for faster test times and higher throughput
• Analyse protocol channels such as CEC, EDID, HPD, ARC and HEC to ensure interoperability
• Improve repeatability of audio and video performance testing with real-time, objective measurements using NI Picture Quality Analysis
