To Set the Sample System
7.1 Timebase Mode
This series of oscilloscope supports three available time base modes: YT mode, XY
mode, and ROLL mode. By default, the time base mode is YT.
Press > Timebase Mode on the front panel, and then rotate the multifunction
knob to select the desired mode. Then, press down the knob to select the mode.
You can also press Timebase Mode continuously or enable the touch screen to select
the desired mode.
7.1.1 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 200ms/div, the instrument enters slow sweep
mode. For details, refer to descriptions in "
ROLL Mode
".
7.1.2 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.
