In conclusion, to use an analog oscilloscope, you need to adjust three basic settings to accommodate an incoming signal:· The attenuation or amplification of the signal. Use the volts/div control to adjust the amplitude of the signal before it is applied to the vertical deflection plates.· The time base. Use the sec/div control to set the amount of time per division represented horizontally across the screen.· The triggering of the oscilloscope. Use the trigger level to stabilize a repeating signal.Also, adjusting the focus and intensity controls enables you to create a sharp, visible display.
