Episode 122: Using an Oscilloscope

This demonstration or student practical activity, from the Institute of Physics, helps students learn to use an oscilloscope to measure voltages. It helps students to understand the use of a cathode ray oscilloscope by showing:
• how the oscilloscope plots a graph of voltage (y-axis) against time (x-axis)
• the effects of adjustments to the scales on the x- and y- axes, time base (time per division) and voltage gain controls (voltage per division).

Following the activity, students should be able to get a stable trace, adjust settings and take measurements of voltage and time from the screen.
