Loop A/V Delay Testing
In this mode, the absolute video and audio delays are measured between the input and output of the
OmniTek system. The A/V Delay Test Sequence is output using the Gen signal generator, and the signal
is taken directly to the equipment under test. The output from the equipment is fed straight back to the
View input.
The View analysis software compares the timing of the output video and embedded audio with the input
video/audio timing. The total propagation delay through the external equipment is calculated and
displayed.
The time delay range that the system is capable of measuring is:
50Hz Systems 60Hz Systems
Audio delay: 0 ~ 7680 ms 0 ~ 6400 ms
Video delay: 0 ~ 7680 ms 0 ~ 6400 ms.
The time delay measurement for the audio may be displayed as samples (at 48kHz) or milliseconds. The
video delay may be expressed as “Frames : Lines : Pixels” or milliseconds. In all cases, measurement
accuracy is better than 1 ms.
