Explanation
Assigning X (Horizontal) and Y (Vertical) Axes: Source
The channels that can be assigned to the X and Y axes are as follows:
X-Y waveform X axis, Y axis
XY1 X: CH1
or
X: CH2
Y: CH2 Y: CH1
XY2 X: CH3
or
X: CH4
(DL1640/DL1640L) Y: CH4 Y: CH3
None X-Y waveforms are not displayed
Number of X-Y Waveforms that can be Displayed
The number of X-Y waveforms that can be displayed is two (XY1, XY2), (or one (XY1)
for the DL1620) . The display of each X-Y waveform can be turned ON/OFF.
Selecting the Display Format: Mode
You can choose from the following three display formats.
T-Y&X-Y: The top window displays normal (T-Y) waveforms. The bottom window
displays X-Y waveforms.
X-Y: Displays only X-Y waveforms.
T-Y: Displays only T-Y waveforms.
Selecting the X-Y Waveform Display Range: T-Range1/T-Range2
The X-Y display shows the range selected on the T-Y waveform.
You can set the start (fine dashed line) and end (coarse dashed line) positions in the
range -5 to +5 div from the center of the waveform display frame. The start and end
positions are not displayed on the X-Y waveform.
The resolution is as follows.
Resolution: T/div × 10/displayed record length
Selecting the Split View: Split (DL1640/DL1640L only)
If this setting is ON, the XY1 and XY2 waveforms are displayed in separate windows.
Further, even if Mode is X-Y, T-Y waveforms are displayed.
Precautions to be Taken when Displaying X-Y Waveforms
• The divided windows of the T-Y waveform display when using the T-Y & X-Y format
are displayed in accordance with the Format setting specified with DISPLAY.
• The zoom function applies only to T-Y waveforms. In addition, Main, Z1, or Z2 can be
selected for the T-Y waveform display.
• When expanding the X-Y waveform, change the Variable parameter of each channel.
The waveform can be expanded or reduced artificially.
• In the modes below, the waveform may flicker when using the T-Y&X-Y display. If the
waveform flickers, change to just the X-Y or T-Y display.
