Making the marker jump inside the main or zoom waveform display frame
When displaying the zoomed waveform or when the display record length is shorter
than the record length, the marker sometimes goes out of the waveform display
frame. In such cases, the marker can be jumped back to the center of the display
frame. The markers can be jumped in the following ways.
• + to Main
Jump (Cursor 1) to the center of the main waveform display frame.
• + to Z1
Jump (Cursor 1) to the center of the Z1 zoom waveform display frame.
• + to Z2
Jump (Cursor 1) to the center of the Z2 zoom waveform display frame.

Cursor measurements of X-Y waveforms
• The types of markers and cursors and the measurement items are the same as the
T-Y waveform (normal waveform).
• The movement range of markers and H cursors are the same as the T-Y
waveform.
• The range of the V cursor is from the right edge (100.0%) to the left edge (–100.0%)
of the screen with the center of the X-Y waveform display frame set as zero. The
selectable steps and the procedure to move the two cursors are the same as for the
T-Y waveform.
• Cursor measurements can be performed on the active display format of the X-Y
waveform. However, when the display format is [Wave+X-Y], the V cursor on the
X-Y waveform cannot be moved. This is because the unit of the V cursor on the T-
Y waveform (time) is different from that of the V cursor on the X-Y waveform
(voltage, current, etc.).
• When the marker is set to a waveform trace that is assigned to the X-axis (set
using the [Cursor1 Trace] menu), the marker will not be displayed because the
waveform on which to move the cursor cannot be uniquely determined.
• When the H cursor is set to a waveform trace that is assigned to the X-axis (set
using the [Cursor1 Trace] menu), the cursor will not be displayed because there
are no data along the Y-axis.
• When the V cursor is set to a waveform trace that is assigned to the X-axis (set
using the [Cursor1 Trace] menu), the cursor will not be displayed because there
are no data along the Y-axis.
• The waveform on which the V cursor is placed is fixed to the waveform trace that is
assigned to the X-axis.
Note
•
The cursors can be set when only the numerical data are being displayed. However, since
the original T-Y waveform is not displayed, the positions cannot be confirmed. Change the
display format in order to check the cursor positions. However, for X-Y waveforms, the V
cursor on the X-Y waveform will not move when the T-Y waveform is also displayed.
•
Cursors cannot be placed on waveforms corresponding to a channel of an element that has
no module installed.
•
The time axis value is measured from the left edge of the screen.
•
When there are data that cannot be measured, “***” is displayed in the measured value
display area.
•
When the marker is outside the waveform display frame, only the values related to the time
axis are displayed.
