Cursor Jump (When Not Displaying the X-Y Waveform)
For V cursors, marker cursors, and angle cursors, you can move M1 to M4, Cursor1, and
Cursor2 to the center of the zoom window. The cursors can be jumped in the following
manner.
• Marker Cursors
to Z1 Make the selected marker jump to the Z1 window.
to Z2 Make the selected marker jump to the Z2 window.
•V Cursor and Angle Cursor
C1 to Z1 Make Cursor1 jump to the Z1 window
C1 to Z2 Make Cursor1 jump to the Z2 window
C2 to Z1 Make Cursor2 jump to the Z1 window
C2 to Z2 Make Cursor2 jump to the Z2 window
Notes When Making Cursor Measurements
• The time axis values are measured from the trigger position.
• The measured value will display “***,” if the measurement is not possible.
• The pulse/rotate setting (see section 5.20) is applied to the X-axis (horizontal)
measurement values in cursor measurements.
Selectable Range of Cursor Position
In cursor measurements, measurement is performed on the data stored in the acquisition
memory not on the displayed data. Since 1001 points along the time axis are used to
displayed the waveform, the number of acquired data points is equal to “record length ×
1.001.” If the record length is set to 10 kW, the number of acquired data points is 10010.
Therefore, 10 points of measured data will exist at the same position on the screen. The
movement range of the cursor position is normally within ±5 divisions around the center
position of the waveform display frame. In this case, if the cursor display position is set to
+5 div, only 1 point out of 10 points can be measured even if there are 10 points of
measured data at the same time axis position. In such case, the cursor position can be
set in the range of –5 divisions to +5.009 divisions (if the record length is set to 10 kW).
In other words, the data at the right end of the waveform display frame can be measured
by setting the cursor position in the range of 5.000 to 5.009 divisions. Because the
number of points at the same time axis position increases as the record length gets
larger, the range varies depending on the record length (5.000 to 5.0099 divisions for
100 kW).
