Oscilloscpe

I dont understand how to calculate things like Voltage and Time period.

Peak to Peak voltage = no. of divisons x Y-Gain

But divions horizontally or vertially?
Voltage is measured verticAlly and time period horizontally.
The time base switch will show the number of seconds, milliseconds or microseconds that correspond to one division horizontally.

Could you get a questions and show me how to find these please?

Would be very grateful!

Oscilloscopes vary and this may not look exactly like one you have used.
They all have a time-base switch that controls the x-axis and another switch (or possibly two if it's a dual beam) that controls the gain on the y-axis.

hey dude, can i just ask you something

is the display on the oscilliscope actually created by just one dot (moving very fast)?

and also, what would you see if you set the time base to a very long time? (say for example, 1 unit = 1 minute)

If it's a single beam scope, then yes it's just one dot moving very fast. (If there are two beams then it's 2 dots.)
If you set the time base to a very slow rate then you see the dot move across from left to right very slowly.
