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.
