14 X-Y Waveforms
You can view the correlation between two waveform levels by assigning the level of one waveform to the X-axis
(horizontal axis) and the level of the other waveform to the Y-axis (vertical axis). There are two X-Y waveform
windows, and you can display four pairs of waveforms in each window (for a total of eight pairs).
You can perform cursor measurements on the displayed X-Y waveforms. You can also observe T-Y (time axis)
waveforms and X-Y waveforms simultaneously.
Turning the X-Y Window Display On and Off (Display)
You can select whether to display each X-Y window.
• ON: The X-Y window is displayed.
• OFF: The X-Y window is not displayed.
Two Pairs of X-Y Waveforms (X-Y Trace Setup)
Two pairs of X-Y waveforms, XY1 and XY2, can be displayed in the window. You can configure the following
settings for each X-Y waveform.
Display on/off (Display)
You can select whether to display each X-Y waveform in the X-Y window.
• ON: X-Y waveform is displayed.
• OFF: X-Y waveform is not displayed.
X Trace and Y Trace (X Trace and Y Trace)
For XY1 and XY2, you can select which waveforms to assign to the X and Y axes from the following options.
CH1 to CH4
1
, 16chVOLT
2
, 16chTEMP/VOLT
2
, CAN
3
, LIN
3
, SENT
3
, Math1 to Math2
1 You can select the channel of an installed module. On a 4-CH module, select sub channel 1 or 2. You cannot
select the input channel of a logic module.
2 When a 16-CH voltage input module or 16-CH temperature/voltage input module is installed. After you select
16chVOLT or 16chTEMP/VOLT, select a sub channel.
3 On a model with the /VE option when a CAN bus monitor, CAN & LIN bus, or SENT monitor module is
installed. After you select CAN, LIN, or SENT, select a sub channel. This cannot be selected on a CAN bus
monitor or CAN & LIN bus monitor module if the data type (Value Type) is set to Logic. On a SENT monitor
module, S&C and Error Trigger sub channels cannot be selected.
• An X-Y waveform cannot be displayed if the waveforms assigned to its X and Y axes have different sample
rates.
• An X-Y waveform cannot be displayed if it is a combination of a sub channel on the 16-CH voltage input
module and a normal channel. You can display an X-Y waveform of two sub channels that have the same
sample rate. The same limitation applied to 16-CH temperature/voltage input, CAN bus monitor, CAN &
LIN bus monitor, and SENT monitor modules.
• An X-Y waveform can be displayed if it is a combination of a sub channel on the 16-CH voltage input
module and a sub channel on a CAN bus monitor module and if the two sub channels have the same
sample rate. The same holds true for 16-CH temperature/voltage input and CAN & LIN bus monitor
modules as well as 16-CH temperature/voltage input and SENT monitor modules.
• X-Y waveforms can be created from normal T-Y waveforms. They cannot be created from zoomed
waveforms.
• Logic waveforms and event waveforms cannot be used to make X-Y waveforms.
• You cannot create an X-Y waveform using one trace whose horizontal-axis unit is time and another trace
whose horizontal-axis unit is frequency.
