The oscilloscope UTD2102CEX+ is used to test whether the signals of the hash board are connected, detect faults faster, provide more prosperous trigger methods, 34 kinds of automatic parameter measurement, and standard mathematical operation functions. Optimize panel operation, significantly improve work efficiency, and efficiently meet the measurement requirements of complex signals.

How to use the oscilloscope:

Debug method:

1. Rotate the SCALE button to adjust the speed to 100ms.

2. Select the CH1 button. The menu contents of CH1 are selected as follows: Coupling (DC 1 MΩ), Bandwidth Limit (full bandwidth), Volts/div (coarse adjustment), Probe (1X).

Note: When the CH1 button is selected, as long as the CH2 button is pressed twice in a row, the oscilloscope will automatically select the CH1 mode when the backlight of the CH2 button is turned off.

3. Rotate the SCALE button to select the 2V gear.

4. Rotate the POSITION button to select the bottom horizontal line.

5. Rotate the LEVEL button to select 0V.

6. When you see the screen below, it means that the oscilloscope has been set up.

7. Insert the plug of the test pen into the No. 1 hole.

8. Switch the switch on the test pen to X1.

9. Clamp the clip next to the test pen to the negative terminal of the hash board. Note: The clip must be fastened, if it is loose during the test, it may cause damage to the oscilloscope.

10. At this point, after using the test fixture for the hash board, you can test the waveform of the signal to help us quickly find the faulty chip in the repair of the hash board.

Notice:

In the actual use of the test pen of the oscilloscope, because the original clip cable is short, it is not convenient for us to test the signal waveform. We need to cut the clip cable and find a cable of about the same thickness to go through it.
