00:00:00,333 --> 00:00:07,466

In this lesson, we will learn about the function introduction of the horizontal control area

2

00:00:09,700 --> 00:00:12,133

First look at the horizontal control area

3

00:00:13,333 --> 00:00:17,300

In the horizontal control area, there are two buttons and two knobs

4

00:00:18,066 --> 00:00:19,933

Take a look at the first little knob

5

00:00:20,366 --> 00:00:25,366

This is horizontal position adjustment, also known as trigger position adjustment

6

00:00:25,933 --> 00:00:30,900

When adjusting this knob, the arrow in the middle of the screen will follow the movement

7

00:00:33,500 --> 00:00:35,433

In the process of measurement and use,

8

00:00:36,033 --> 00:00:40,100

we need to adjust the trigger position to the position of 0 in the middle of the screen

9

00:00:41,666 --> 00:00:46,866

The second button is the horizontal control menu, this function is generally rarely used

10

00:00:49,433 --> 00:00:52,833

The third is to quickly return to zero in the horizontal position

11

00:00:54,433 --> 00:01:00,600

For example, we have adjusted this horizontal position to the left of the screen, or beyond the screen range

12

00:01:03,000 --> 00:01:06,133

You can press the horizontal position fast zero button,

13

00:01:08,200 --> 00:01:12,133

and its arrow will quickly return to the zero position in the middle of the screen

14

00:01:16,800 --> 00:01:20,333

The fourth is the big knob, which is used to adjust the time base,

15

00:01:20,700 --> 00:01:24,000

that is, the adjustment of the time in the middle of the screen

16

00:01:27,233 --> 00:01:29,566

This is the time base adjustment knob

17

00:01:33,166 --> 00:01:39,033

Fifth, this is the input terminal of the external trigger channel, which is generally not used

18

00:01:39,400 --> 00:01:42,733

Next, let's look at the trigger control area

19

00:01:44,000 --> 00:01:47,466

There are 1 knob and 4 buttons in the trigger control area

20

00:01:47,766 --> 00:01:50,766

The first knob is the adjustment knob for the trigger level

21

00:01:51,266 --> 00:01:56,300

When turning this knob, you can change the size of the trigger level in the lower right corner

22

00:02:03,866 --> 00:02:07,133

The second button, this is the trigger settings menu

23

00:02:08,000 --> 00:02:10,633

Its source (trigger channel) can be changed by software button,

24

00:02:11,000 --> 00:02:15,766

and can be set as channel 1, channel 2 or external trigger channel, etc.

25

00:02:18,366 --> 00:02:23,866

Slope, also called edge type, is generally set to rising edge or falling edge

26

00:02:24,266 --> 00:02:27,800

When measuring the power supply, the rising edge is generally used

27

00:02:28,466 --> 00:02:33,866

When measuring power-down, the low-level effective signal is generally used to measure the falling edge

28

00:02:34,066 --> 00:02:37,366

Trigger mode, here are automatic and normal

29

00:02:39,600 --> 00:02:44,466

If we want to use the single trigger function, we need to press the single trigger button next to it,

30

00:02:48,533 --> 00:02:50,300

the coupling is set to DC

31

00:02:51,533 --> 00:02:56,366

Next, there is a mandatory trigger here, which is generally not used

32

00:02:58,466 --> 00:03:03,600

Next, there is a trigger line here, showing the position of the vertical starting point

33

00:03:04,233 --> 00:03:06,766

This function is generally not commonly used

34

00:03:07,133 --> 00:03:12,400

Ok, this is the function introduction of horizontal control area and trigger control area
