@AcousticBruce Go to your trigger settings and set it to single shot. Then a rising edge for charging or a falling edge for discharging. Then change the threshold of the trigger to be whatever you need it to be. Change the time base to 1 second per division or whatever. Then if you push run-stop you can set the scope to be ready to trigger on the voltage transient.
@Afrotechmods
Sort of. You will need a special accessory called a current probe. These are typically expensive. You can do it ghetto style though, using a shunt resistor. Take a resistor of around 0.1 ohms and measure the voltage on both sides of the resistor. Then use the subtract function on the scope to display the difference in voltage across the resistor. Then from Ohm's law, volts / 0.1 ohms = the current
@Afrotechmods
@SubaruB4RSK Don't rely solely on automatic measuring features. Use the cursors to measure things manually, or just calculate things from the number of volts per division.

This aged like fine wine. Short, mention the key points, demonstrate with examples, it has everything in under 2 minutes! Thank you!
@Afrotechmods
I didn't know you could tune drums. With an electric guitar you could view the amplified signal on an oscilloscope and measure the frequency. Different notes have different frequencies and you can google for a chart.
@Afrotechmods
@DubCampbell Low cost for 30Mhz... would have to be a used 200+Mhz analog scope from eBay. 450Mhz is impossible for less than many thousands of dollars - you might find a spectrum analyzer useful though.
@Afrotechmods
Your probe is acting like an antenna, picking up the AC signal from nearby power lines. If you connect your probe to something you want to measure (like a battery's voltage) the interference should disappear. Also, your scope's main power cable should be the 3 pin type so there is an earth connection.
@Afrotechmods
You can definitely get a decent digital scope used. I did! But not for $150.... more like $300. If you are working with micros and only have a $150 budget, you might be best off with a USB based scope.
@Afrotechmods
Glad you liked it. SOR are welcome to add any of my videos they want to the website
@Afrotechmods
It doesn't really have anything in terms of logic analyzer functionality. It'll just display the binary waveforms on screen and you'll have to decode stuff by hand.

@Afrotechmods "I think i'd enjoy it and be good at it, but there's just no way I'd be content with a teacher's salary." I've read and heard similar comments many times and I think it's a shame that this seems to be the state of affairs in the US. Here in Germany, teachers are well paid and well-respected. Anyway, this is a nice introduction to oscilloscopes. Thanks.
@Nabo00o
@Afrotechmods I agree on that, once you get used to reading the divisions you have super tool in your hands. Just place a 1 ohm resistor in series with a load and you can read the amps peak to peak directly (or lower the ohms and then recalculate the amps).
@RandyLott
@somebody301 A spectrum analyzer displays the frequencies contained in a signal. It does a "Fast Fourier Transform" to convert the signal from the time domain to the frequency domain. It's important to RF engineering or for testing the frequency response of an amplifier. A scope is much more useful if you have a choice between the two.

My favourite non-meme youtube channel! Thanks for your work!
@siddharthchauhan83
Excellent!! I wish you were teaching us at my University. This tutorial just made everything so simple I am doing my Masters in wireless communications but i have no experience with oscilloscopes, unfortunately our prof dint have time at all to explain the functioning of one. This video tutorial really helped me in a big way ...many thanks.
@antofro
Very well spoken presentation. Theory is all good and abstract until circuits works. Thanks so much for you contribution. I have learned a lot from your videos.

@thesurvivalist98
Thanks, this really helped me,as when I started watching the first video, I didn't know what an ocillisocope was. I just subbed!
@whiskeyify
I'm not trying to advertise for Sencore...but I used to own one and it's a great scope. You set it on auto and hardly ever have to touch it...just touch your test point and it automatically adjusts itself. It displays the waveform and underneath that is a digital readout that tells you the DC voltage and AC voltage.
