7 Using the 780B Test Instrument Installer Test Utility
This section provides procedures for diagnosing HDMI networks using the automated Installer Test. The
features and functions described in this section are included as a standard feature. The Installer Test
enables you to quickly and simply identify common interoperability problems. The Installer Test enables you to
conduct step by step diagnostics toward the source
—upstream (
Source Test) , toward the sink
—downstream
( Sink Test) , or in a looped configuration around a repeater device ( Repeater Test ). You can also conduct both
and upstream and a downstream diagnostic test at the same time using the Link Test.
Table 7-1 below describes what items are tested with each test in the Installer Test.
