Persistence; Xy Mode - TECPEL OS Series User Manual

OS Series Handheld DSO & DMM

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
