Introduction
The digital storage oscilloscope (DSO) is a versatile tool for the engineer. It has the ability to sample and store voltage waveforms, giving it the ability to “capture” transient waveforms and also the ability to perform mathematical operations on the sample values. Like any tool though, it has its limitations, and careful operation is required to interpret results correctly.
For professional design and testing, a constant DC voltage is usually required where the voltage can be adjusted from the front panel – such devices are DC power supplies. A power supply may have one pair of terminals, or two (a ‘dual’ power supply) or three pair (a ‘triple’ power supply). Some can be operated in series or parallel. You need to become familiar with the laboratory power supplies so that in future when you need to use one you know how they operate.
Another useful device for testing is the “function generator”. This device is capable of generating sinusoidal, triangular, and square waves of varying frequency and amplitude. It is generally used as the “input signal” to a circuit so that a circuit’s time and frequency characteristics can be determined.
