Autoset tell the scope to examine the inputs and choose a best guess at reasonable input gain and timebase settings. You should see a display similar to that shown in Fig. 2. If you don’t get this, ask for help now. Oscilloscope vertical, horizontal and trigger controls Now that you have a signal, explore the e ects of the various scope controls.
