a. Touch the plot or use the left and right arrow keys to move the cursor to the
desired location on the plot.
b.
Press ALT > F3 Cursor Home to move the cursor to the beginning of the plot.
c. Press ALT > F9 Cursor End to move the cursor to the right side of the plot.
d. Press ALT > F4 Clear Cursor to remove the cursor.
5.5 Change the cursor type
You can change the type of cursor to display different types of information on a plot. The
types of cursors vary based on the selected plot type.
Procedure
1. Plot the data.
2. With a plot displayed, press ALT > F2 Cursor Type.
3. Press F2 Cursor Type until the appropriate cursor type appears.
Option Description
Delta Time The amplitude and time of the current location are shown just below the plot.
When you press the Mark key, the current location is marked. As you move
the cursor, the time difference (Delta-T) between the marked point and the
new cursor position displays in the upper right corner of the plot. The screen
displays a frequency (Delta-F), which is calculated as the reciprocal of the
time difference. This is useful for waveforms.
Difference
Family
The difference families of the data are calculated and the first family is used
to draw the difference cursors. This is similar to the “Sideband” cursors, but
the “Next Peak” key changes to a “Next Family” key. This lets you jump
through the calculated difference families, and increases the number of
sideband cursors.
Harmonic The primary cursor is red and all harmonics related to the primary frequency
are displayed with black square boxes.
Harmonic
Family
The harmonic families of the data are calculated and the first family is used to
draw the harmonic cursors. This is similar to the Moving harmonic option,
except that you can jump to the next family of harmonics rather than the
next peak.
Moving
Harmonic
Similar to the Harmonic cursor, but the fundamental frequency is not
stationary. As you move the cursor, the harmonic markers move to reflect
the harmonic frequencies of the current cursor location.
Normal An individual cursor appears on the plot. The frequency and amplitude
update as you move the cursor.
Sideband Displays the Delta-F and values between a reference and active cursor (Delta-
A).
