An Introduction to the Oscilloscope and Time Varying Currents Purpose: To introduce the oscilloscope as an instrument for measuring voltage differences in both DC and AC circuit, and using it to study time-dependent voltages in circuits which include capacitors. Procedure: 1. Survey the control panel and identify SEC/DIV, VOLTS/DIV, and the channel 1 and 2 controls. Get comfortable with controls and functions of controls. 2. Make sure all buttons are in “out” position, and that intensity is set to minimum. 3. Set the display so that it shows a single sine wave, and draw the graph. 4. Read and record the period of the wave from the horizontal scale. 5. Calculate the frequency and compare it on the dial of the frequency generator. Record results. 6. Repeat 3 – 5 for 2 other frequency settings. 7. Use time measurement cursors, repeat measurements. Record results. 8. Turn all units off whenever you change or add to a circuit. 9.
