National Instruments PXIe-1491 digital audio and video analyser

National Instruments has announced the company’s latest multimedia test offering, the NI PXIe-1491 digital audio and video analyser for HDMI, DVI and mobile devices. Designed for performance testing and high-throughput test of consumer devices such as set-top boxes, Blu-ray players, smartphones and tablets, the product delivers automated, high-performance measurements to eliminate subjective manual inspection.

The device 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, which delivers world-class quality-of-experience (QoE) metrics such as peak signal-to-noise-ratio (PSNR) and structural similarity index metric (SSIM). In addition, the 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 device is suitable not only for at-home consumer electronics but also testing of aerospace and defence systems, automobile rear-view camera and infotainment systems, in-flight entertainment systems, video conferencing and professional audio/video equipment.
