CRO:Measuring Voltage & Frequency

Ok, today i'm gonna continue our discussion on Cathode Ray Oscilloscope. In last post i did mention one of the purpose using CRO is to measure voltage & frequency of a waveform.
To do this, we must understand the function of 'Y-gain & Time base'

Y-Gain:
- it is used to set the scales for the y-axis. Let say if u set the button at 10V/division..it means the y-axis has a scales of 0V,10V,20V,30V .....i.e each division has 10V.

Time base:
-meanwhile timebase is used to set the scales for x-axis. If the timebase is set to 10ms, i.e each division has 10miliseconds.
