OWON HDS-N Series Handheld DSO & DMM 8-Advanced Function of Oscilloscope

Figure 47: Vectors Style

8.7.2 Persistence

With Persist function selected, the displayed saved original data gradually decay in color and the

new data are bright in color; with infinite persistence mode selected, the oscilloscope keeps all

past traces of the displayed waveform.

8.7.3 XY Mode

This mode is only applicable to CH1 and CH2.The X-Y format plots the CH1 input as X-axis and

CH2 input as Y-axis. This display mode is convenient for viewing the phase relationship between

CH1 and CH2; when the oscilloscope is under the sampling mode in which no trigger is found, the

data appear in light spots.

Operations for various control keys are shown as below:

■ The CH1 Volts/Div and CH1 Zero for CH1 (see "System" on P15) are used to set the

horizontal scale and position.

■ The CH2 Volts/Div and CH2 Zero for CH2 (see above) are used to set the vertical scale

and position continuously.

The following functions do not work in the XY display mode:

■ Reference or digital value waveform

■ Cursor

■ Time base control

■ Trigger control
