Example 4: Video Autoset
In this example, you are trying to troubleshoot where a composite
broadcast video signal is getting lost in the master control feed. You
need to quickly acquire a waveform at different test points. Do these
steps:
1. Connect the composite video signal to oscilloscope channel 1
using proper adapters and a 75 ohm terminator.
2. Push the Acquire MENU button.
3. Push the Autoset bottom button.
4. Push the Video Autoset side button. If a broadcast-standard video
waveform is present, the oscilloscope displays a stable video
waveform that is triggered on all lines.
5. Connect the oscilloscope to the other test points until you locate
where the signal is lost. You do not need to change any
oscilloscope settings.
