4.7 - Using an Oscilloscope Flashcards
1
Q
what happens if pd is applied across the x plates
A
the spot deflects horizontally
2
Q
what happens if the pd is applied across the y axis
A
makes the spot deflect vertically
3
Q
what is the displacement of the spot proportional to
A
the applied pd
4
Q
what are the x plates connected to
A
the oscilloscopes time base circuit
making them move across left to right
moves ar a constant speed
5
Q
what is connected to the y plates
A
the pd via the y input so moves up and down whilst it moves to the side creating a wave form
because the vertical displacement is proportional pd applied at y plates y input is calibrated in volts per cm
6
Q
y axis
A
height or amplitude x y gain =peak pd
7
Q
how to calc frequency of alternating pd
A
1=f/t
8
Q
pd/ displacement
A
= y gain
