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.
b) Using cursors:
Activating the "Cursor" button displays the cursor softkeys:
The audio analyzer uses two cursors which are identified by the symbols
⃝
and X. These symbols are used to mark the measured points in the graph (see
the example graph below).
Only one cursor is active and can be moved in the graph at any one time. The
active cursor is displayed with a solid line; the inactive cursor is displayed with
a broken line.
The
⃝
<--> X button is used to activate the
⃝
and X cursor alternately.
If, for example, the cursor was activated with the
⃝
cursor button, the following
softkeys appear:
The
Vert
A button activates a vertical cursor on Trace
A; this cursor can then
be moved with the rotary knob.
The step size with which the cursor is being moved can be set via additional
softkeys of the next level which are called with the "Movement" softkey.
The
Movement
button opens the next softkey level where various step sizes
for moving the cursor are offered. The currently selected step size is indicated
in brackets in the second label field of the "Movement" button.
