The use of the two [[ADD-ON_DVI-RX]] boards allows to create two physical test points where the video stream under investigation in available in a easy-to-handle format, that is color components and syncs are available separately. At these points, it is possible to connect a standard oscilloscope through single-ended passive probes. Video stream contents are generated in order to embed a pattern that is easly detectable (1). Thus oscilloscope trigger can be configured in order to detect this condition and to measure precisely the latency between the two points of the chain where the probes are connected as shown in the picture. This measure includes the delay due to the second DVI-to-RGB conversion that it is assumed to be neglectable with respect to the overall latency.

(1) Stream 1080p60 and is composed by an endless sequence of 1 black frame and 59 white frames.
