Frequency
Definition :
The horizontal scale on the CRO[1] screen makes it very simple to measure time and frequency. The size of the signal on your CRO display should be increased if you want to ensure precision while measuring a frequency so that the waveform can be converted more easily. Initially, the time can be determined by counting the number of flat partitions from one end of the signal to the other whenever it passes the flat line and using the horizontal scale on the CRO
The signal's time period can then be determined by increasing the number of flat segments through time or division.
