OSCILLOSCOPE | period

 

OSCILLOSCOPE

horizontal sensitivity → time period → frequency

 

 

Description:

Using horizontal sensitivity to evaluate time period. By measuring the period of the wave on the horizontal axis of the oscilloscope screen and reciprocating that time value (in seconds), you can determine the frequency in Hertz.
Application exercise:
The oscilloscope is used to measure the characteristics of a voltage. The time period of a sinusoidal alternating voltage is here studied exclusively, without worrying about the Vpeak.


Definition

Oscilloscope: type of electronic test instrument that graphically displays varying signal voltages.
