Tip
You can also press down HORIZONTAL
to directly switch to the delayed sweep mode.

Time Base Mode

Press MENU in the horizontal control area (HORIZONTAL) at the front panel and
then press Time Base to select the time base mode of the oscilloscope. The default
is YT.

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 greater than or equal to 200 ms, the
instrument enters slow sweep mode. For the details, please refer to the introduction
of slow sweep in "Roll Mode".

XY Mode

In this mode, the oscilloscope changes the two channels from voltage-time display
mode to voltage-voltage display mode. The phase deviation between two signals
with the same frequency can be easily measured via Lissajous method. The figure
below shows the measurement schematic diagram of the phase deviation.
