The difference between peak-to-peak and amplitude(AMP) is shown in the
figure above.
7.3 Trigger
There are Three options in the trigger menu: “Trigger Mode” / “Trigger Type”
and “Trigger level”.
Trigger Mode
can be selected from "Auto" and "Normal".
For “Auto” mode, if a waveform trigger is detected, the waveform signal will be
used for triggering. If the oscilloscope cannot detect the trigger condition, it will
automatically force the trigger to display the waveform.
For “Normal” mode, the oscilloscope will not refresh the display until a
waveform trigger occurs. So there may be no waveform on the screen in this mode.
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".
"Automatic" is suitable for novices. The oscilloscope detects the waveform
position and amplitude and automatically sets the trigger level.
"Manual" is suitable for people who are familiar with the oscilloscope. When
using the “Single” function or the trigger mode is "Normal", you should use the
"manual" option. Under this option, the trigger level can be manually adjusted by the
user.
7.4 Display
In this menu you can set persistence / roll mode and brightness.
“
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 at any time base, resulting in
a long time before the screen is refreshed for large time base.
7.5 Aux
There are two options of "Calibration" and "FFT" in the auxiliary menu.
When the probe is removed, if there is a significant deviation between the
waveform position and the zero arrow position, it indicates that calibration is required.
Please remove the probe and USB cable before calibration, and then click the
"OK" button. The oscilloscope then starts self-calibration. Do not perform any
operation on the oscilloscope until it is completed. After completing the calibration,
