I've been playing with the build in wave generator on the oscilloscope and learning about AM modulation. I learned how to use the FFT math function as well which was neat since I could see the message and carrier frequencies instead of just drawing them out in class. The carrier frequency is set at 5 Mhz while the message frequency is set at 10khz. I set the center frequency on the FFT to 5Mhz with a span of 50 KHz. These oscilloscopes are freaking awesome.
