780C Multi-Interface Interoperability Tester – User Guide
6 Using the 780C Test Instrument to Test HDMI or HDBaseT Source
Devices
This section provides procedures for testing HDMI source devices such as DVD players, set top boxes and
HDMI and HDBaseT outputs on repeater and distribution devices.
6.1
Testing Video from an HDMI Source Device
This subsection describes how to test the video on HDMI source devices.
6.1.1
Connection Configurations for Testing HDMI Source Devices
The 780C's HDMI input port acts as a "reference" HDMI sink device. Therefore it enables you to emulate a
known good HDMI sink device to conduct a basic confidence test of an HDMI source device or output of an
HDMI distribution or repeater device. This test ensures that you are receiving a valid HDMI video signal by
displaying the timing of the incoming signal and informing you whether it is HDCP encrypted or not. You can
run this test in three configurations:
Source device connected directly to the 780C HDMI IN connector.
Source device connected to the 780C HDMI IN connector through a repeater device.
780C HDMI OUT and HDMI IN ports acting as both as a known good source and a known good sink
connect to both the input and output of the repeater device.
In all cases the 780C is emulating a sink to test an upstream source. In the third configuration, the 780C is
emulating both an HDMI source and sink. These test configurations are shown below.
