Questions
• Explain the functionality of the VOLTS/DIV (volts per division, sometimes referred to the vertical scale) knob on the oscilloscope. If displaying a simple sine wave on the screen, how does the appearance change when you increase or decrease the setting?
• Explain the functionality of the TIME/DIV (time per division, sometimes referred to as the horizontal scale) knob on the oscilloscope. How does adjusting the setting of this knob affect the picture of the displayed waveform?
• Explain "triggering" on the oscilloscope and its role in displaying the waveform on the screen.
• How do older, phosphor-coated screen oscilloscopes work?
