Which of the following describes a trigger function on an oscilloscope?
It determines the signal's amplitude.
It freezes the display for static observation.
It adjusts the signal's frequency.
It ensures the waveform starts at a specific point for consistent display.
In an oscilloscope's control panel, what does the AC/DC coupling switch do?
Turns the device on or off.
Filters the signal to show only AC or DC components.
Adjusts the brightness of the screen.
