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.

The electronics workstation is a notorious area in the Maker Hub where messes are left behind. The same RESET THE SPACE principles apply to the electronics workstation as they do everywhere else in the Maker Hub. Clean up after yourself when you finish please.
