X-Y Format

This format is useful for studying phase relationships between CH1 and ch2 (CH3

and CH4 can’t be used).CH1 in the horizontal axis(X) and CH2 in the vertical axis(Y),

the oscilloscope uses a none-trigger acquisition mode, data is displayed as dots.

Press MENU→Time Base→X-Y to enter X-Y mode.

Figure 2-37 X-Y display format

The oscilloscope can acquire waveforms with any sampling rate in Y-T mode (up to

2GSa/s for single channel or half channel

[1]

). But in X-Y mode, up to 1GSa/s can be

used and the default is 250MSa/s. Generally, the lower the sample rate is, the better

the Lissajous graphic will be.

NOTE [1]: Half channel indicates selecting one of the channels in CH1 and CH2, or in CH3 and

CH4.

The following modes or functions will not work in X-Y format.

 Auto cursor measure mode

 Track cursor measure mode

 REF and MATH Operations

 Delayed Scan Mode

 Vector Display Mode

 Horizontal knob

 Trigger Controls(excluding MODE button)
