Video Cable Specific Tests
Sin/x Impulse Test
In this test a multi-pulse signal on a single video horizontal line is generated. This rigorous test rejects any cable with variations over 1dB at the receiving end. In the graph for your cable, note the uniformity of the six peak amplitudes of the multi-pulse groups, when compared to the broad reference amplitude marker on the far left. (For multi-channel assemblies, all channels are tested. The results for the green channel are graphed, as that channel has the most impact on picture quality.)Signal Loss
In this demanding test a multi-burst signal is generated on a single video horizontal line. For relative differential loss, a variation of up to only 1dB is allowed for your cable. Differential loss is length dependent.Channel Matching (Multi-channel cables only)
This test determines color balance in a multi-channel video cable. Up to 0.5dB difference is allowed.
