: Use the Volts/Div and Sec/Div knobs until the signal is visible and fills most of the screen. Avoid the "Auto-Set" button if you want to understand what you're seeing, as it can sometimes produce misleading results.

Getting a readable signal requires adjusting three primary sections of the front panel: Oscilloscopes: how to use them, how they work

Understanding basic oscilloscope operation | Rohde & Schwarz : Use the Volts/Div and Sec/Div knobs until

: A digital oscilloscope uses an Analog-to-Digital Converter (ADC) to take thousands or billions of snapshots ("samples") of the voltage per second. These points are stored in memory and connected to draw the final waveform. These points are stored in memory and connected

: Attach the probe to a channel (e.g., Channel 1).

: Sets the time scale. Turning this knob stretches or compresses the wave horizontally to show more or fewer cycles.

: Connect the probe tip to the scope’s built-in CAL or square wave terminal. Adjust the probe’s compensation screw until the square wave is perfectly flat with sharp corners.
