Question
Explain the function of the input coupling switch (AC, DC, GND) of an oscilloscope
Solution
The input coupling switch on an oscilloscope is used to control how the signal from your device under test (DUT) is transferred to the oscilloscope. It has three settings: AC, DC, and GND.
-
AC (Alternating Current) Coupling: This setting blocks the DC component of the signal and only allows the AC component to pass through. This is useful when you want to observe the AC signal without the DC offset. It can also be used to observe signals with a frequency above the cut-off frequency of the built-in high-pass filter.
-
DC (Direct Current) Coupling: This setting allows both AC and DC components of the signal to pass through. This is useful when you want to observe the entire signal, including any DC offset. It's the most commonly used setting.
-
GND (Ground): This setting disconnects the input signal and connects the input directly to the ground. This is useful when you want to observe the noise level of the oscilloscope or set the zero level of the vertical scale.
In summary, the input coupling switch on an oscilloscope allows you to control what parts of your signal are observed, whether that's just the AC component, both the AC and DC components, or just the noise level/zero level.
