If the volts per division setting on the oscilloscope is 5 and the signal moves upward 3 vertical divisions, what is the signal voltage?

• A. 150 V
• B. 100 V
• C. 15 V
• D. 5 V

Answer: (C)

To determine the signal voltage using the oscilloscope's settings, you need to multiply the volts per division setting by the number of vertical divisions the signal moves. In this case, the volts per division is set at 5 V. The signal moves upward 3 vertical divisions. Therefore, the calculation to find the voltage is: Voltage = (Volts per division) × (Number of divisions) Voltage = 5 V/division × 3 divisions = 15 V This calculation confirms that the signal voltage is indeed 15 V, making it the correct answer. The relationship between the setting on the oscilloscope and the visual movement of the signal provides a straightforward way to calculate voltage levels in a relatively simple manner, which is a fundamental concept for Biomedical Equipment Technicians when interpreting data from oscilloscopes.
