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.
Now lets look at this video example,
About Me
- Cikgu Ahmad
- I am a full time specialist Physics tutor operating in Klang Valley. I've been educating student for more than 10 years. My specialty is to transform student that had failed their physics subject into a better result. Even some of them managed to get an A in their final exam, You can read their testimony in this blog. I provide home tuition for physics subject to those living nearby KL especially around W.Maju, Ampang,Melawati and Setiawangsa. At the same time i 'm giving online tuition to all malaysia & overseas student. For tuition centre looking for a physics tutor, i'm also able to give seminar and conduct weekly classes. Meanwhile,for school teachers who are organising physics seminar, i am happy to assist u in that aspect. If u have enquiry on my service, do contact or whatsap me at 017-2877589 or email me at celikfizik @ gmail . com
