FemEng lab Episode 3: The Oscilloscope and wave generator

Hello everyone!

Welcome to our third video. This time we will talk about the oscilloscope and the wave generator. These two devices are very important in an electronics lab. The first one allows us to see the signal in our circuit, while the second, as its name implies, allows us to generate an input signal.

You may have seen the symbols below when you draw your circuits. Sometimes you can imagine that a DC voltage is a battery, because batteries produce a DC voltage. But how is an AC voltage generated? Batteries do not produce an AC power supply themselves, so when AC is required, the function generator is needed to generate an AC signal.

And what about the oscilloscope? With this instrument, you will be able to see your signal, and it will automatically make a really nice graph with the form of your voltage signal in real-time.

So in this video, I will go through the basic set up of how to use these two devices.

I hope this video was useful and has given you a better understanding of some of the apparatus you may come across in the lab.

In next week’s video, I will continue with a bit more explanation on the oscilloscope. It will be released next Monday so be sure to follow us on all of our social media, here is our Linktree!
