NI delivers PXIe-1491 digital audio and video analyser

National Instruments has unveiled 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 NI PXIe-1491 is said to deliver automated, high-performance measurements to eliminate subjective manual inspection.

The NI PXIe-1491 is shipped with NI Video Measurement Suite, a test suite for analysing a wide variety of video standards.

The company also offers add-ons such as AudioMASTER software, designed for in-depth audio testing including frequency response and THD, and Picture Quality Analysis (PQA) software.

PQA software delivers metrics such as peak signal-to-noise-ratio (PSNR) and structural similarity index metric (SSIM). It also 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 NI PXIe-1491 enables the audio/video analyser 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.”
