National Instruments has announced its newest multimedia test offering, theNI PXIe-1491 digital audio and video analyzer 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 NI PXIe-1491 delivers automated, high-performance measurements to eliminate subjective manual inspection.
The NI PXIe-1491 is shipped with NI Video Measurement Suite. 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 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 parallelized measurement algorithms.
The benefits of NI PXIe-1491 extend beyond at-home consumer electronics. Applications include testing of aerospace and defense systems, automobile rearview camera and infotainment systems, in-flight entertainment systems, video conferencing and professional audio/video equipment.
“The NI PXIe-1491 enables the audio/video analyzer industry to think beyond the manual solutions used today,” said Charles Schroeder, director of marketing for test at National Instruments. “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.”
