3 .4 Cursor Measurements
After displaying and reviewing the signal, the next step
will introduce cursor measurements of the signal. Again,
briefly press the AUTOSET key once followed by the
CURSOR/MEASURE key. You can now select the desired
type of measurement cursor from the menu. Press the
soft menu key MEASURE TYPE to open the appropri-
ate selection menu. You can specify your selection with
the universal knob in the CURSOR/MENU section of the
control panel. Turn the knob CCW until the entry V MAR-
KER is marked in blue. Press the MENU OFF key to close
the menu or wait until it automatically closes after a few
seconds. Now two cursors will be shown along the signal
as well as the measurement results on the bottom of the
display. Press the universal knob to select the active cursor
and turn the universal knob to position the cursor. The
cursor measurement results will be shown on the bottom
of the display. In this example with the entry “V marker”,
the display includes the voltage at both cursor positions,
their difference, and the time difference between the cur-
sor positions. To switch off the cursor, press the CURSOR
MEASURE key again.

In addition to cursor measurements the most important
signal parameters can be displayed. Your oscilloscope of-
