The Teledyne LeCroy quantumdata M21 Video Analyzer for HDMI and DisplayPort testing offers a wide array of benefits to design and engineers in R&D as well as professional A/V installers for testing HDMI and DisplayPort source devices. The M21 instrument is also equipped with an HDMI 48Gb/s video generator enabling test engineers and pro A/V integrators to run a variety of video, audio and protocol tests on digital video displays. With both an HDMI video analyzer and a video generator, the M21 can be used to test distribution equipment and cables as well.

The portable size, battery operation and large user-friendly touch screen provide convenience to complement the rich feature set. The user interface design and test functions greatly reduce Time-to-Insight whether running tests on distinct devices or entire digital video distribution networks.
