The Oscilloscope and the Function Generator: Some introductory exercises for students in the advanced labs Introduction So many of the experiments in the advanced labs make use of oscilloscopes and function generators that it is useful to learn their general operation. The osc. is a graph displaying device that display the electrical signal based on the input to its probes. Swift (1667-1745) OBJECTIVE To learn to operate a cathode ray oscilloscope. An oscilloscope’s trigger function synchronizes the horizontal sweep at the correct point of the signal. With a load significantly larger than 50 Ω, the function generator will supply double the voltage it is set to. Such an instrument is obviously useful for the design and THEORY The oscilloscope, or scope for short, is a device for drawing calibrated graphs of voltage vs time very quickly and conveniently. Oscilloscope Basics Intro. In an oscilloscope, the CRT produces the electron beam which is accelerated to a high velocity and brings to the focal point on a fluorescent screen. An oscilloscope, previously called an oscillograph, and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time. The following block diagram shows the general purpose CRO contraction.The CRO recruit the cathode ray tube and acts as a heat of the oscilloscope. Oscilloscope As A Measurement Tool. Refer to this figure as you read the following list and descriptions of the various controls and related circuits involved. Usually the Y axis represents the voltage and the X axis time.
The Oscilloscope Vision is the art of seeing things invisible. Trigger controls allow you to stabilize repetitive waveforms and capture single-shot waveforms. It shows in real time how signals change over time. Function generators are …

Introduction To Oscilloscope ("osc.") A simplified sample scope front panel layout is shown in Figure 3.
Oscilloscope Parts and Function. This is essential for clear signal characterization.
That is why the oscilloscope has a sine wave with amplitude of 1 V, or a peak to peak voltage of 2 V. There are two ways to fix this: 1.
The key parts of an oscilloscope that relate to the controls shown in Figure 3 are the following: The arbitrary/function generator expects a 50 Ω terminal load. This is useful for measuring such things as clock frequencies, duty cycles of pulse-width-modulated signals, propagation delay, or signal rise and fall times. An oscilloscope's primary function is to provide a graph of a signal's voltage over time.
