Probing Principles
AC and DC Coupling
You can cou ple the signal input to the oscilloscope with either DC or AC co upling. DC coupling shows both the DC and A C
measurement components. AC coupling removes the DC component from the displayed signal.
1. This low-frequency square wave is
displayed using AC coupling. The signal
exhibits low-frequency rolloff.
2. Press the DC Coupling button to display
the waveform as truly square.
WARNING. To prevent personal injury or
probe damage, make sure that the input DC
current does not exceed the probe specification
when you use AC coupling.
