First, bring up the instrument toolbar, right-click on the menu bar, and then select the instrument, so that there is a tick status in front of the instrument, as shown in the figure

Then you will find the instrument bar appears on the right side of the work area, as shown in the red frame

The first one in the instrument column is a multimeter, the fourth one in turn is the oscilloscope, and the fifth one is the four-track oscilloscope;

First look at the usage of the oscilloscope. The oscilloscope has two channels, which can observe two signals at the same time. For example, if we want to see the voltage change across a resistor, then connect the A channel of the oscilloscope and the two ends of the resistor in parallel, as shown in the figure

If you also want to see the voltage changes across the capacitor, then connect the two ends of the capacitor in parallel to the B channel, as shown in the figure

When the circuit diagram is very complicated, the signals of each channel may look messy. We can set the color of different signal channels. How to set it? It is set by setting the color of the wire connected to the oscilloscope, for example, select the wire connected to the positive pole of the B channel of the oscilloscope, right-click, and then select the color segment, select a desired color, as shown in the figure

After setting, we start to simulate the observation signal, double-click on the oscilloscope you placed to open the display panel, and then turn on the simulation switch, as shown in the figure

Since the scale has not been set, the signal display effect may be inappropriate as shown in the figure

The fourth trace oscilloscope is the fifth in the instrument toolbar, as shown in the figure,

The so-called four-track oscilloscope has 4 channels, ABCD, as shown in the circuit in the figure, if you want to observe the four signals of resistance R1, resistance R2, capacitor C1, and inductance L1, then connect them to the corresponding channels respectively. The color setting method has been I will not repeat them here in the previous experience introduction; finally, the G terminal of the four-track oscilloscope should be connected to the ground, as shown in the figure

Now look at the simulation results, which is slightly different from the setting method of the oscilloscope. The four-track oscilloscope selects the corresponding channel by selecting the middle disk as shown in the red frame on the left, and then sets the channel ratio. Adjust to the appropriate display result as shown in the right figure. Note that the observed signal is only the voltage value of the connection terminal, and does not necessarily represent the voltage across the device. For example, the signals of the C and D channels connected to L1 and C1 in the figure only represent the voltage at one end. Voltage.

The signals observed above are all internal triggers. The default is A channel trigger, you can set other channels; click A> in the lower right corner and then select one of A B C D channels, as shown in the figure

What does the oscilloscope have another T channel for? This is used to connect the external trigger signal in the external trigger mode. First, select external in the trigger setting, as shown in the left figure, and then connect the trigger signal to the T channel as shown in the right figure;
