RIGOL Chapter 3 To Set the Horizontal System

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 and the

default is Y-T.

Y-T 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”.

X-Y Mode

In this mode, the oscilloscope changes the two channels from voltage-time display

mode to voltage-voltage display mode. Wherein, the X axis and Y axis tracks the

voltages of CH1 and CH2 respectively. The phase deviation between two signals with

the same frequency can be easily measured via Lissajous method. The f igure below

shows the measurement schematic diagram of the phase deviation.
