Press the Acquire button; select Wave Display in the bottom menu, select Type in
the right menu. You can switch between Dots and Vect.
Persist
When the Persist function is used, the persistence display effect of the picture tube
oscilloscope can be simulated. The reserved original data is displayed in fade color
and the new data is in bright color.
Press the Acquire button; select Wave Display in the bottom menu, select Persist
Time in the right menu. Turn the G knob to select different persist time, including
OFF, 100ms
～
10s and Infinity. When the "Infinity" option is set for Persist Time,
the measuring points will be stored till the controlling value is changed.
Select Persistence OFF to turn off persistence and clear the display.
Select Clear to erase the results of previous acquisitions from the display. The
oscilloscope will start to accumulate acquisitions again.
XY Mode
XY Mode is used to display the amplitude from one waveform against the amplitude
from another. The data point from the first waveform specifies the horizontal location,
while the corresponding data point from the second waveform specifies the vertical
location for each displayed point.
The red waveform is CH1 versus CH2; the purple waveform is CH3 versus CH4.
The oscilloscope is set in the un-triggered sample mode: the data are displayed as
bright spots.
The operations of all control knobs are as follows:
The Vertical VOLTS/DIV and the VERTICAL POSITION knobs of CH1 are
used to set the horizontal scale and position of the red waveform.
The Vertical VOLTS/DIV and the VERTICAL POSITION knobs of CH2 are
used to set the vertical scale and position of the red waveform.
The Vertical VOLTS/DIV and the VERTICAL POSITION knobs of CH3 are
used to set the horizontal scale and position of the purple waveform.
The Vertical VOLTS/DIV and the VERTICAL POSITION knobs of CH4 are
used to set the vertical scale and position of the purple waveform.
Note:
1. If one of the paired channels is on, the other is off, after entering the XY mode,
the closed channel will be turned on automatically.
2. In the XY mode, if you turn off a channel, the other channel that pair with it will
be turned off automatically.
