The Function Generator and the Oscilloscope
OBJECTIVE
To learn the fundamentals of using the function generator and the digital oscilloscope.
THEORY:
The Function Generator is a voltage source that can produce time varying voltages (waveforms).
There are four standard waveforms: sine, square, triangle and ramp (sawtooth) as shown in Figure 1.
The function generator also allows us to control the amplitude and the frequency of the waveform.
Figure 2 shows some characteristics of the waveforms: the voltage of one peak (V p) and the peak-to-
peak voltage (Vp-p), which is twice of Vp for symmetric waveforms. The period (T) is also shown which
is related to the frequency as f=1/T.

The oscilloscope is basically a graph-displaying device - it draws a graph of an electrical signal. In
most applications the graph shows how signals change over time: the vertical (Y) axis represents
voltage and the horizontal (X) axis represents time. This simple graph can tell you many things about a
signal. Here are a few:
► You can determine the time and voltage values of a signal.
► You can calculate the frequency of an oscillating signal.
► You can see the "moving parts" of a circuit represented by the signal.
Refer to Appendix I or II for the details of the Oscilloscope you are using.

PROCEDURE:
1. Generate a sine wave of 5 volts peak-to-peak and 1.5 kHz frequency. Display this wave on the
oscilloscope and save it on disk and draw a 1 cycle sketch in figure 3.
(Use 2 Volt/ div and 200us/div)

Vp-p = 5 volts Vp = 2.5 volts Vrms= 1.76 volts-rms Period (T) = 6.67x10^-4 s
