在仿真期间查看数据
在 Simulink® 中使用示波器和查看器在仿真期间可视化和测量信号，以调试模型并验证设计。您可以将信号连接到 Scope 模块，或将 Floating Scope and Scope Viewer 添加到模型中而不连接信号线。使用仿真结果验证设计并进行迭代。要了解详细信息，请参阅Prototype and Debug Models with Scopes。
示波器中的测量设置使您能够测量在示波器窗口中显示的信号的各个方面。例如，您可以使用游标测量信号值、计算信号统计量、查找峰值、显示双电平测量（如信号转换、过冲、下冲和周期），甚至设置触发器来同步重复信号并在发生特定事件时暂停显示画面。
示波器容器使您能够将 Simulink 模型的多个示波器停靠到单个窗口中。该容器提供便捷的界面，您可以从中可视化信号并管理示波器的设置。
您也可以查看仿真数据并使用 Record 模块将其记录到工作区、文件或同时记录到两者。使用仿真数据检查器，您可以检查和比较数据及仿真结果，从而验证模型设计并进行迭代。

精选示例
Time Scope Measurements
Measure performance characteristics of a pulse width modulated sinusoid. The example contains a model, which you can modify to view the effects of parameter changes on rise time, fall time, overshoot, undershoot, pulse width, pulse period, and duty cycle measurements. The example also models a rising edge trigger and you can perform basic statistical operations (mean, median, RMS, maximum, minimum) and measure the frequency and period of the pulse period via cursors and peak finding.
