通过前面板旋钮控制游标，实现游标沿X、Y轴平移。-Through the front panel knob to control the cursor, the cursor along the realization of X, Y-axis translation.

通过前面板旋钮完成对波形图横轴、纵轴放大与缩小。-The front panel knob to complete the waveform horizontal, vertical axis zoom in and out.

通过前面板旋钮，控制波形图横坐标轴，纵坐标轴最大值，最小值的大小，进而实现对波形的缩放、平移操作。-Through the front panel knob to control the waveform horizontal axis, vertical axis maximum, minimum size, and thus realize the waveform zoom, pan operation.
