Let’s get started by looking at some function generator signals. 1. Turn on a function generator. The digital ones will take a few seconds to complete internal tests, but the analog ones will be ready right away. 2. Turn on the digitaloscilloscope. After the scope completes its internal tests, press the \Clear
