How to Use an Oscilloscope


Can airplane smoke detectors detect vape is a powerful tool for electrical circuit analysis. It can do things no multimeter can do: show you a waveform, and help you see what is going on in a circuit, instead of just guessing at what’s happening. Almost all products today contain electronic components, so understanding oscilloscope how to use is an essential part of designing, testing, and debugging a product.

The first thing you need to do is make sure your scope is turned on and that the channel probe input is set to “1x” or “10x.” 10x will attenuate the signal by a factor of 10, which is fine for most signals.

Next, attach the probe to your circuit. Make sure that the center of the probe is connected to the signal and the side (usually an alligator clip) is attached to the ground. You can then adjust the volts/div, time/div, and vertical position controls to frame the signal on the screen. Try adjusting each of these a few times to get a feel for how they work.

Now you’re ready to start triggering the scope. There are several types of triggers, but most are very simple: an edge trigger tells the scope to start drawing a trace when the signal voltage crosses a threshold value, which you can set to catch either a rising or falling edge; a pulse trigger is a short, varying slope of the signal, which can be set to trigger on a positive or negative slope; and a single-shot trigger sets up a one-shot sequence that starts every time the circuit’s capacitor discharges.
