Oscilloscope Functionality and Waveforms

This video tutorial by Mike from The Geek Pub introduces oscilloscopes, comparing them to multimeters. It explains how oscilloscopes measure voltage over time, unlike multimeters that provide point-in-time readings. The video covers the oscilloscope's display, controls, and how to interpret waveforms like sine and square waves. It also discusses the features of oscilloscopes, including probes and channels, and demonstrates practical applications such as testing an Arduino or a Commodore 64. The tutorial concludes with tips on using oscilloscopes for troubleshooting electronic devices.

What is the main advantage of using an oscilloscope over a multimeter?

• It measures voltage over time.

• It is more portable.

• It provides a single point in time reading.

• It can measure resistance.

What does the horizontal axis on an oscilloscope's display represent?

• Voltage scale

• Time scale

• Frequency scale

• Amplitude scale

How can you adjust the time scale on an oscilloscope?

• By turning the horizontal control knob

• By adjusting the power supply

• By turning the vertical control knob

• By changing the probe

What type of waveform is represented by a cycling pattern between -170V and +170V?

• Square wave

• Sine wave

• Triangle wave

• Sawtooth wave

What is the RMS voltage of a 5V square wave at 50% duty cycle?

• 10 volts

• 0 volts

• 2.5 volts

• 5 volts

What feature allows you to view multiple signals on an oscilloscope simultaneously?

• Multiple channels

• Zoom feature

• Single probe

• Grid divisions

What does moving the 1X - 10X button on a probe do?

• Attenuates the probe by a factor of 10

• Changes the color of the waveform

• Decreases the voltage

• Increases the frequency

What is the purpose of the ground lead on an oscilloscope probe?

• To measure frequency

• To connect to the ground of the device being probed

• To connect to the power supply

• To adjust the voltage scale

How can you check if an Arduino's oscillator crystal is functioning correctly?

• By observing a 16MHz oscillation on an oscilloscope

• By listening for a sound

• By checking the voltage with a multimeter

• By measuring resistance with a multimeter

What should you see on an oscilloscope when probing the SID chip's output line in a Commodore 64?

• No signal

• A flat line

• A sine wave

• Waveforms matching the music
