Level

map_level_wheel

When manual trigger level selection has been turned on using the “At/Norm.” button, the trigger level can be set using the “Level” wheel. Use the “+/-“ button to set whether the ascending or the descending flank shall trigger the sweep.

The following images show examples for different trigger settings:

sample_trigger_level_autolevel_b
The “At/Norm.” button is off (=automatic level selection),
the “+/-“ button is off (=trigger on ascending flank)

sample_trigger_level_rising_50_percent_positive
The “At/Norm.” button is on (=manual trigger level setting),
the “Level” wheel is turned to about half of the signal amplitude,
the “+/-“ button is off (=trigger on ascending flank)

sample_trigger_level_falling_50_percent_positive
The “At/Norm.” button is on (=manual trigger level setting),
the “Level” wheel is turned to about half of the signal amplitude,
the “+/-“ button is on (=trigger on descending flank)

sample_trigger_level_out_of_range
The “At/Norm.” button is on (=manual trigger level setting),
the “Level” wheel is turned to a position lower than the lowest voltage of the signal,
therefor the signal cannot be triggered, the screen remains empty.
