as the TV trigger source.
The selected trigger source is displayed in the upper-right
corner of the display. Turning the Trigger Level knob does not

automatically set to the sync pulse. Trigger coupling is
automatically set to TV in the Trigger Mode/Coupling menu.

these sources, a 75 Ω terminator (such as an Agilent 11094B) should be
connected to the oscilloscope input.
