Timebase Mode
DS8000-R series supports three available time base modes: YT mode, XY mode, and
ROLL mode. By default, the time base mode is YT.
Click the function navigation icon
at the lower-left corner of the externally
connected screen to open the function navigation menu. Click the acquisition icon
to open the acquisition setting menu. Click Timebase Mode to select the
desired time base mode.
YT Mode
In this mode, the Y axis represents voltage, and the X axis represents time.
Note: Only when this mode is enabled, can delayed sweep be turned on. In this
mode, when the horizontal time base is equal to or greater than 200 ms/div,
the instrument enters slow sweep mode. For details, refer to descriptions for
slow sweep in "ROLL Mode".
XY Mode
In this mode, both the X axis and the Y axis represent the voltage. The mode
changes the display from voltage-time display mode to voltage-voltage display. You
can use the Lissajous method to measure the phase deviation of the two input
signals whose frequencies are the same. The following figure shows the
measurement schematic diagram of phase deviation.
