Method of connecting analog oscilloscope:

1. The analog oscilloscope connection is relatively simple, and different oscilloscopes are slightly different.

2. Adjust the oscilloscope to xY mode. Some oscilloscopes can be selected by pressing the buttons, while others are selected by the knob to xY mode. Please study by yourself.

3. Connect the BNC cable to the oscilloscope and power on. Normally, a horizontal line will be displayed. Adjust the xY vertical channel parameters, about 1V/div, and then adjust the x Y attenuation so that the horizontal line is in the display frame. It can also pass the VI test version. The x attenuation potentiometer on the upper side can assist in adjusting the length of the horizontal line. If the test pen iis short-circuited, a vertical line will be displayed under normal circumstances.

How to connect a digital oscilloscope:

For digital oscilloscopes, enter the xY mode through the menu or keys. The two channels of xY are adjusted to 1V/div, and the single-track oscilloscope only needs to adjust the Y channel. Adjust the time base to 1-5 milliseconds.

When the oscilloscope is not connected, the screen should be a bright spot. Adjust the horizontal and vertical to center the bright spot. Connect the VI tester. Normally, it should be a horizontal line. Adjust the 103 potentiometer at the top of the VI board to make the horizontal line in the display frame. , Half a grid or 1 grid to the edge is better. Short-circuit the test leads, and the display should be a vertical line at this time.
