Oscilloscope Voltage Formula

The following formula is used to calculate the voltage, vertical scale per division, or the number of divisions on an oscilloscope.

V = S \cdot D

Variables:

V is the voltage
S is the vertical scale per division (V/div)
D is the number of divisions

To calculate the voltage, multiply the vertical scale per division by the number of divisions. To find the vertical scale per division, divide the voltage by the number of divisions. To determine the number of divisions, divide the voltage by the vertical scale per division.

What is an Oscilloscope?

An oscilloscope is an electronic test instrument that graphically displays varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time. It is used to observe the change of an electrical signal over time, allowing for the measurement of various signal properties such as amplitude, frequency, and phase. Oscilloscopes are essential tools in the fields of electronics, telecommunications, and engineering for diagnosing and troubleshooting circuits and systems.

How to Calculate Oscilloscope Voltage?

The following steps outline how to calculate the voltage, vertical scale per division, or the number of divisions on an oscilloscope.

First, determine the voltage (V) if it is not given.
Next, determine the vertical scale per division (S) if it is not given.
Next, determine the number of divisions (D) if it is not given.
Use the formula V = S * D to calculate the missing variable.
After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Voltage (V) = 10V

Vertical Scale per Division (S) = 2V/div

Number of Divisions (D) = 5
