Great series. If you don't already, you should teach.

Terrific video (the whole set). You most certainly have as knack for teaching.

Excellent! >:)

thank you for these videos!!

Hey man, I know people say this all the time, But I found one of your videos and have become an addict. You explaint sooo well. Why arent my university teachers like you... Anyway THANK YOU

great stuff!! much appreciated!!

@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.

Hi, I heard about spectrum analizer, it works similiar to oscilloscopes or not? and, what is a logic analyzer?
You are an excellent teacher! I'm a 64 year old musician/amateur (ham) radio enthusiast and electronics hobbiest and I don't own an oscilloscope. Since I spend more time at home these days, I figure it's time to make or buy a scope and a tone generator to assist me in a wide variety of repairs and prototype projects. What would be a low cost scope for monitoring audio modulation on a 30 Megahertz AM signal? What about 450 Mhz? Can I use a PC/software for this?

@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.

What if I want to capture the charge of a capacitor on a dc circuit with a 5 second charge? How can you have the scope capture this and have it stay on the screen so you can study it? I have the same scope.

@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.

I have another question lol I need to find the peak-peak voltage of something should the number but jumping around when the probe is connected?
Because I have a project coming up and the PK-PK voltage has a big outcome over the overall loudness of the sound.

@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.
