The M21 Video Generator / Analyzer is a handheld video generator and

analyzer that enables you to conduct quick verification testing of your

digital video source and display devices and distribution equipment. The

M21 is equipped with both an HDMI video generator and video analyzer

function and a DisplayPort video analyzer function. These interfaces

enable you to test audio, video and related protocols—HDCP, EDID,

CEC & infoframes, HDMI FRL and DisplayPort Link Training. The M21’s

portability makes it ideal for your bench and even for use in the field with

its battery power capability.

A 10-inch color touch display makes the M21 easy and convenient to

use. When testing a digital video source device you can toggle between
