Example of using an oscilloscope
Foreword: This article is a function record after I use the oscilloscope. It is mostly a record of common functions (I often use it, and I will add it after I use it). I write this article so that I can review and read it at any time to prevent forgetting. , other students can watch it as needed.
1. Oscilloscope pattern
I use the oscilloscope of Zhiyuan Electronics, as shown in the figure below:
The functions of the buttons on the right are explained below.
2. General introduction
The functional block diagram of the oscilloscope is as follows:
- Segmented lines, measuring the difference
A线between and in the imageB线, canX轴be eitherY轴. - Oscilloscope image stops or starts after key press
- Level-triggered capture mode
- Clear, don't know what's the use
- Automatically adjust the waveform image to the appropriate position
- Corresponding to 1,
Per: Persistence time switch,Cur: Switch measurement to X-axis or Y-axis,Int: Line brightness setting - Segmentation mode, set image segmentation
- Zoom in on the mid-segment image
- Scroll mode, the waveform appears from right to left
- Zoom in or out of the overall image, adjust the time to roll over the waveform
- You can slide the overall waveform to the left and right
- Adjust the size of a single channel waveform (I understand that the specific unit of measurement should be adjusted to cause the observed waveform to shrink or enlarge)
- The waveform of a single channel moves up and down
- channel selection
- To save the oscilloscope image, you can save it to
U盘or内置Flash, you need to press (18 in the figure) before using itUtility, and choose whether the saved image is saved in the U disk or Flash. - Measurement item selection display
- math operation selection
- Storage selection, you can choose to save the image location, method, save image type, etc.
- Adjust the trigger level in trigger mode
- Trigger mode setting
3. Distribution Introduction
3.1 Segmented line settings
The position of the function setting is shown in the figure:
the knob in the left frame can adjust the position of line A and line B on the image back and forth; the
button on the right can adjust the other functions of line A and line B
Persist: after pressing it, the afterglow time will be displayed
as the picture shows
- Line A and Line B
- After pressing
Intensitythe key, the brightness of the display line is displayed - The difference between line A and line B
3.2 Single channel waveform adjustment
The functional area is shown in the figure:
Rotate ①, the image changes as shown in the figure:
It can be found that the waveform is significantly enlarged.
Rotate ②, the image changes as shown in the figure:
It can be found that the yellow waveform has moved downward as a whole.
3.3 Overall Waveform Image Adjustment
The functional area is as shown in the figure:
Rotate ①, the image changes as shown in the figure:
You can see that the overall image has shrunk.
Rotate ②, the image changes as shown in the figure:
You can see the image move to the right.
3.4 Scroll Mode
The function area is as shown in the figure:
①Select the scrolling mode
②Adjust the imagesliding time
The waveform image is as follows:
waveformright to leftmove
3.5 Measurement Display Selection
The functional area is shown in the figure:
the position shown in the figure
The oscilloscope image is as shown:
Click to select the measurement item and select the data you want to display:
Note: The selected measurement is only the display of a single channel , press ① to select the channel.
The display is as shown in the figure:
3.6 Storage options
The functional area is as shown in the figure:
after pressing, it will be as shown in the figure:
3.7 Trigger capture mode selection
The functional area is shown in the figure:
①Enable the trigger
②Adjust the trigger level
③Select the trigger capture function, as shown in the figure below:
You can choose the trigger method, trigger type, etc.
That sums it up!
