Quantum Data Debuts 780 Series Test Generators for 4K HDMI
The Quantum Data 780 Series of handheld test generators are battery-powered, portable video and audio generators and HDMI analyzers that enable you to conduct quick, on-site verification testing and troubleshooting of your HDMI system and analog video (VGA or RGB) displays. The 780 Series include a reference HDMI source and a reference HDMI sink interface allowing you to test audio, video and HDMI protocols — HDCP, EDID, CEC and infoframes — of any type of HDMI device: sources, repeaters and sinks.
There are four models:
The 780: The 780 supports HDMI testing at pixel rates up to 165MHz and TMDS rates up to 225MHz for deep color on the output and pixel rates up to 150MHz on the HDMI input.
The 780A – 4K: The 780A supports testing of 4K Ultra HD HDMI 2.0 devices at 50/60Hz. And it also tests HDMI 2.0 features including 4:2:0 pixel encoding on sources and sinks and EDID emulation for testing HDMI 2.0 sources and distribution devices.
The 780B – 4K: The 780B supports all the features of the 780A including 300MHz on the HDMI Rx and Rx ports for testing of 4K Ultra HD HDMI 2.0 devices at 50/60Hz, but adds a larger screen (7 inches). In addition to supporting of testing of HDMI 2.0 devices including tests for 4:2:0 pixel encoding on sources and sinks and EDID emulation for testing HDMI 2.0 sources, it also outputs 21:9 aspect ratio formats. Finally, an automated EDID test option enables automated testing of source devices’ handling of a variety of EDIDs.
The 780C – 4K: The Quantum Data 780C Multi-Interface Interoperability Tester is a portable digital video generator and analyzer that enables you to run tests on various digital video devices and network distribution devices on site or in the R&D lab. The 780C instrument provides a 7 inch color touch screen for operation and for viewing status of outgoing and incoming video and audio. The 780C is equipped with multiple interface types including HDMI, HDBaseT, 3G-SDI and component analog. Testing digital interfaces is supported by both an output port and an input port to allow testing of digital video sources, displays, audio devices and distribution devices. Testing hybrid converter devices supporting 3G-SDI, HDMI, HDBaseT distribution networks is possible as well.
