Sweep/Control
you have dropped the trigger line that far below the displayed signal level, rather than simply
dropping it down to the displayed signal level.
Note that other corrections, specifically External Gain and Ref Level Offset, modify the actual trace
data as it is taken and therefore ARE taken into account by Trig Level.
Couplings This same level is used for the Video trigger source in the Trigger menu and for the Video selection in
the Gate Source menu.
Preset Set the Video Trigger Level –25 dBm on Preset. When the Video Trigger Level becomes the active
function, if the value is off screen, set it to either the top or bottom of screen, depending on which
direction off screen it was.

Controls the trigger polarity. It is set positive to trigger on a rising edge and negative to trigger on a falling
edge.
