Display Controls

• An intensity control to adjust the brightness of the waveform. As you increase the sweep speed of an analog oscilloscope, you need to increase the intensity level.
• A focus control to adjust the sharpness of the waveform. Digital oscilloscopes may not have a focus control.
• A trace rotation control to align the waveform trace with the screen's horizontal axis. The position of your oscilloscope in the earth's magnetic field affects waveform alignment. Digital oscilloscopes may not have a trace rotation control.
• Other display controls may let you adjust the intensity of the graticule lights and turn on or off any on-screen information (such as menus).
