​While discussing a lab scope waveform: Technician A says the horizontal movement of the waveform represents voltage. Technician B says the horizontal voltage scale must be adjusted in relation to the expected voltage signal. Who is correct?
A)​A only
B)​B only
C)​Both A and B
D)​Neither A nor B

Quizplus · Accepted Answer

The horizontal movement of a waveform on a lab scope actually represents time, not voltage. The vertical movement represents voltage. Therefore, Technician A's statement is incorrect. Technician B's statement is also incorrect as it confuses the concepts; it's the vertical scale that is adjusted for voltage, not the horizontal scale. The horizontal scale is adjusted to view the waveform over a specific time period.
