You can use an oscilloscope to display the input and output of a circuit at the same time by:
- Ameasuring the input on the X axis and the output on the Y axis
- Bmeasuring the input on the X axis and the output on the Z axis
- Cmeasuring the input on the Y axis and the output on the X axis
- Dutilizing a dual trace oscilloscope
Correct answer: D — utilizing a dual trace oscilloscope. From the official ISED question bank, verified word for word.
Why
A dual trace oscilloscope contains two separate input channels and internal circuitry that lets you view two different signals on the same screen at the same time, which is exactly what you need to compare a circuit's input and output simultaneously. The full explanation — and one for every question — is in Pro.
