cursors and markers can only be operated using the softkey bar; the required soft-
keys are displayed at the bottom of the screen as soon as the graphical window
has the focus.
The softkeys are arranged in several levels; the lower levels are accessed by
actuating the respective button. Actuating the "Back" button redisplays the higher
level.
a) Setting markers:
Pressing the "Marker" button calls up the Marker softkeys which are used in
this example to first select Trace A so that markers can be set.
The next softkey level appears simultaneously:
The "Track to Max" button is used to set a marker at the maximum value of the
curve, i.e. the fundamental in this example of THD+N measurement.
The "Harmonics" button is used to mark the harmonics of the fundamental indi-
cated by the marker.
Pressing the "Back" button twice calls up the first softkey level again.
