8 Menu introduction
Once the menu is open, press the mV or V button to switch menus.
8.1
Measurement
There are 14 measurement options available, as shown below
:
Frequency, Peak-to-Peak, Duty cycle, Amplitude, RMS, Average, Period, +Pulse
width, -Pulse width, Max, Min,Top, Base, -Duty cycle.
The difference between peak-to-peak and amplitude(AMP) is shown in the
figure above.
8.2
Trigger
There are 3 options in the trigger menu: “Trigger Mode” ,“Trigger Type” ,
“Trigger level”.
Trigger Mode
can be selected from "Auto" and "Normal".
For “
Auto
” mode, if a waveform trigger is detected, the waveform will be used
for triggering. At this time, the waveform can be displayed stably. If the oscilloscope
cannot detect the trigger condition, it will automatically force the trigger to display the
waveform, but because there is no suitable trigger condition, the waveform will not be
displayed steadily.
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 "
Auto-adjust " 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
