124 Agilent InfiniiVision 2000 X-Series Oscilloscopes User's Guide
9 Triggers
1 Press the [Trigger] key.
2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob
to select Video.
3 Press the Source softkey and select any analog channel as the video
trigger source.
The selected trigger source is displayed in the upper-right corner of the
display. Turning the Trigger Level knob does not change the trigger level
because the trigger level is automatically set to the sync pulse. Trigger
coupling is automatically set to TV in the Trigger Mode and Coupling
Menu.
It is important, when using a 10:1 passive probe, that the probe is correctly compensated.
The oscilloscope is sensitive to this and will not trigger if the probe is not properly
compensated, especially for progressive formats.
