Tip

You can also press down HORIZONTAL SCALE (delayed sweep shortcut key)

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.
