What an Oscilloscope Shows That a Multimeter Cannot
Series navigation: Episode 1: The Roadmap · Episode 2: Digital Multimeter and LED Circuit · Episode 3: Voltage Divider Under Load · Episode 4 What you will learn: How an oscilloscope turns voltage into a graph of voltage versus time. What problem it solves: A digital multimeter may show one reasonable number while hiding pulses, ripple, noise, and timing errors. What you will be able to do: Identify volts/div, time/div, trigger level, probe attenuation, frequency, period, amplitude, and duty cycle on a basic oscilloscope display.
