Additional test features for the Quantum Data 780

Quantum Data™, a worldwide provider of video test equipment, today announced the release of an Auxiliary Channel Analyzer (ACA) feature on the 780 Handheld Test Instrument for HDMI.

The 780 is a battery powered, portable multimedia A/V signal generator and analyzer that can quickly check the HDMI digital ports on HDMI 1.3 devices such as HDTVs, projectors, repeaters, A/V receivers, players, set-top-boxes, etc.   The 780 instrument's optional Auxiliary Channel Analyzer (ACA) feature is available in two configurations:
1) Emulation monitoring mode where the 780 monitors the DDC channel(s) and hot plug events while emulating an HDMI source or sink device (available now);
2) Passive monitoring mode where the 780 passively monitors the DDC channel(s), hot plug events and CEC buses (available soon). The ability to passively monitor two separate sets of auxiliary data is especially useful for analyzing interoperability problems in an HDMI system comprised of three devices (source, repeater and sink).  

The ACA features enable installers, lab technicians and engineers to monitor DDC transactions such as HDCP and EDID as well as hot plug related events while emulating device(s) in the HDMI system. Since the 780 can emulate a known-good source and/or a known-good sink, operators can sequentially substitute for each device in the system to isolate an interoperability problem. The 780 can even monitor on both sides of a repeater device while emulating both the source and sink devices for trouble isolation.  
The 780 combines versatility, portability with ease of use. Whether in the development lab or out in the field, the 780 is an ideal tool for investigating interoperability problems or conducting routine testing of sources and sinks.
