4 Using the 780C Test Instrument to Video and Audio Pattern Tests on
Sink Devices
This chapter provides procedures for running audio and video pattern tests on high definition sink devices such
as HDTVs and projectors. The features and functions described in this chapter are provided with the standard
780C; no options are required. The following signal types are supported.
 HDMI (via the HDMI physical connector)
 DVI (via the HDMI physical connector)
 HDBaseT (via the HDBaseT physical connector)
 3G-SDI (via the SDI physical connector)
 YPbPr Component analog (via the HD VGA connector)
 RGB Analog (via the HD VGA connector).
4.1 Making Physical Connections - HDMI
The first step in testing a sink device is to make the HDMI physical connections between the 780C and the
device(s) under test.
4.1.1 Connecting the 780C to the Display Device - HDMI
Use the following procedures to make the physical connections from the 780C to the display device under test.
1. Make the cable connection between the appropriate the 780C video output connector (e.g. HDMI OUT or
ANALOG) connector and the input connector of the HDTV using the cables supplied.
2. Alternatively you may connect from the 780C video output connector to an HDTV through an HDMI
repeater device such as an A/V receiver. In this case make the HDMI connection between the HDMI OUT
connector on the 780C and the HDMI input of the HDMI repeater device using an HDMI-to-HDMI cable.
Then connect the HDTV to an active output on the repeater. The following illustrations depict the typical
test configurations.
