: How long it takes for a signal to go from a low to high state (typically 10% to 90%).
: 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.
: Sets a specific voltage threshold that the signal must cross to trigger a display refresh. Oscilloscopes: how to use them, how they work
Getting a readable signal requires adjusting three primary sections of the front panel:
: Connect the ground clip to the circuit's ground reference and the probe tip to your test point. : How long it takes for a signal
: Attach the probe to a channel (e.g., Channel 1).
: Acts as a synchronization tool. It tells the oscilloscope exactly when to start drawing the wave so that repetitive signals appear stable and "frozen" on the screen rather than a blurry mess. Essential Controls : Sets a specific voltage threshold that the
: Sets the time scale. Turning this knob stretches or compresses the wave horizontally to show more or fewer cycles.
