Question 1 of 1

Technician A says that most signals can be captured using the 20/20 Rule - that is, by setting up the scope to capture a range of 0-20v on the vertical scale and setting the time base to 20ms per division. Technician B says that a DSO does not capture a signal in real time - rather, it samples the voltage input and then plots that data on the screen. Who is correct?

Technician A

Technician B

Both A and B
Neither A nor B
