Introducing the latest video test instrument from Quantum Data for testing HDCP interoperability in HDMI systems. The HT-180 Handshake Tester for HDMI offered by Quantum Data enables users in R & D labs, service provider interoperability labs and field service techs to identify the root cause of HDCP, EDID and hot plug related interoperability problems in HDMI systems. The HT-180 provides HDMI ports for passive connection into an HDMI system comprised of a source (e.g. set top box or DVD), repeater (e.g. AVR controller) and an HDTV.
