graph), the cursor value is interpolated linearly at the pixels between the measured
values.
If the number of recorded measurement points in the graph is greater than the
number of pixels available for display, the largest measured value in each case is
displayed at the corresponding pixel with X and Y value.
●
"Next Sample "
Selecting the "Next Sample" button moves the cursor to the next measured value
with every increment.
If the graph is displayed relatively small or the number of recorded measured val-
ues (samples) displayed is greater than the number of pixels available in the
graphical field, the cursor sometimes does not appear to move (it remains on the
same pixel). However, the associated display fields always show the currently
selected measurement point with X and Y-value.

"Next Value "
Only the "Next Value" setting is available here; the cursor moves to the next mea-
sured distortion point (harmonic or intermodulation product) with each increment.
The softkey movement indicates the step size.
All of the step-size settings for cursor movement described here only affect the cur-
rently selected cursor and are only applicable in the selected graphical window. This
means that when a different cursor is activated or a different graphical window is
selected, the cursor is moved using the settings applicable there.
The selected step size applies equally to vertical and horizontal cursors.

Cursor in traces with several scans
If a trace consists of several scans, the cursors only move along one scan and indicate
the x and y-values of this scan. The scan number displayed in the bottom left-hand cor-
ner of the graph in the respective display field indicates which scan is being analyzed.
