3 Basic Procedures
3-18
Entering Scope Parameters for Signal Tracing
You enter or change scope parameters to format the x-axis and y-axis in a Scope
window. Other parameters include the number of graphs in a one Scope
window and whether the scope is connected to a continuous or discrete model.
If you entered the scope parameters for running a simulation, you can skip this
procedure. This information is repeated here if you did not run a simulation.
After you add a Scope block to your Simulink model, you can enter the scope
parameters for signal tracing:
1 In the Simulink window, double-click the Scope block.
A Scope window opens.
2 Click the Parameters button.
A
Scope parameters dialog box opens.
3 Click the General tab. In the Number of axes box, enter the number of
graphs you want in one Scope window. For example, enter
1 for a single
graph. Do not select the
floating scope check box.
In the
Time range box, enter the upper value for the time range. For
example, enter
1 second. From the Tick labels list, choose all.
From the
Sampling list, choose Sample time and enter 0 in the text box.
Entering
0 indicates that Simulink evaluates this block as a continuous time
block. If you have discrete blocks in your model, enter the
Fixed step size
you entered in the Configuration Parameters dialog box.
Your
Scope parameters dialog box will look similar to the figure shown
below.
