Seriously though, you won’t learn how to properly set triggers, display signals, or troubleshoot problems if you rely heavily on the AUTOSET button. Though the oscilloscope may look complicated, it’s not hard to understand once you get to know it. For the purposes of this certification, the AUTOSET button is off-limits, so you can save yourself the seven years’ bad luck.

The units of the graph tell us a lot about what we are looking at. The y-axis is voltage, and the x-axis is time. So, an oscilloscope will show—in real time—how a voltage signal is changing over time. One key skill we need to learn when using the oscilloscope is to manipulate the scales of the x-axis and y-axis so that you can see the voltage signal clearly and meaningfully on the oscilloscope’s display.

Set up a breadboard with a 10kΩ potentiometer as a voltage divider. Connect an LED's anode (the longer leg) to the wiper of the potentiometer. Connect a 560Ω resistor to the cathode (the shorter leg), and connect the other side of the resistor to ground. See the demo circuit diagram to the right for reference.

Part 1: Connect a DC power supply to the input and set it to 10V. Slowly adjust the potentiometer to determine how much voltage and current is needed to turn on the LED. Measure the voltage and current using the digital multimeter.

Part 2: Disconnect the DC power supply from the input and connect the function generator to the input. Connect the oscilloscope probes to both the input and output of the potentiometer to display the waveforms. Set the function generator to a sine wave to turn the LED on and off. Experiment with a DC offset and a square wave.
