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 5.14) is applied to the X-axis (horizontal)
measurement values in cursor measurements.
• If the sub waveform window is displayed when using the dual capture function, cursor
measurements are made on the sub waveform. To make cursor measurements on the
main waveform, turn OFF the sub waveform window in the DUAL CAPTURE menu.
• The results of cursor measurements on the sub waveforms of the dual capture
function are displayed in italics.
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, if the record length is set to 10 kW, 10 points of measured data will exist at
the same position on the screen. The cursor display 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).
