Timebase Mode
MSO8000 series supports three available time base modes: YT mode, XY mode, and
ROLL mode. By default, the time base mode is YT.
Press Acquire → Timebase Mode on the front panel, and then rotate the
multifunction knob
knob to select the mode. You can also press Timebase Mode continuously to select
the mode or enable the touch screen to tap the desired mode and select it.
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 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.
