For “
Normal
” mode, The oscilloscope will not refresh the display until there is a
waveform trigger. Therefore, in this mode, the screen waveform may not refresh or
there is no waveform. It is suitable for measuring discontinuous waveforms and
requires users to adjust the trigger level in advance.
Trigger type
includes rising and falling edges. Rising edge trigger means that
the waveform crosses the trigger level line upward, and a trigger condition occurs.
Trigger level
include "automatic" and "manual".
"Auto" is suitable for trigger mode = auto, the oscilloscope detects the waveform
in real time and automatically adjusts the trigger level.
"Manual" When the “single” is used or the trigger mode is "Normal", the
"Manual" option should be used. Under this option, the trigger level can be manually
adjusted by the user.
Trigger source
indicates which channel's waveform is currently used for
triggering. In the dual-channel mode, CH1 or CH2 can be selected. If the channel is
used as the trigger source, its waveform can be stable. If the waveform frequencies of
the two channels are different, the waveform of the other channel will be unstable.
8.4
Display
“
Persistence
” is to make the historical waveform remain on the screen for a
while and then disappear. Optional persistence options are: None, 1s, Infinite. When
Infinity is selected, the waveforms that have appeared on the screen will remain
forever and will not disappear.
“
roll
” is to display the waveform while sampling. Only when the time base is
greater than or equal to 200ms will the roll mode be entered. If roll is turned off, the
waveform will be displayed after one screen is sampled, resulting in a long time
before the screen is refreshed for large time base.
“XY”
mode is a way that channel 1 is used as the X axis and channel 2 is
displayed on the Y axis. It can be used to view
Lissajous
graphics etc.
"
Hi-rate
" refers to the waveform refresh speed. When turned on, many frame
waveforms will be superimposed. When turned off, only one waveform is displayed
at a time. Note that it is always “on” when the time base <=200ns.

Settings
When the FFT option is turned on, the CH1 waveform can be FFT calculated and
displayed. FFT display options are: logarithmic, linear, and music spectrum.
Measuring FFT results is not supported.
The calibration option is used to calibrate the zero point of the oscilloscope.
Self-calibration is required when the outside temperature changes or when there is a
zero offset due to aging. Remove the probes before calibration.
Furthermore:
1. In the settings, you can set whether to automatically shut down, if you choose
