The Digital Oscilloscope was previously known as an oscillograph, and its informal name is a scope, cathode-ray oscilloscope (CRO) or a DSO, Digital Storage Oscilloscope. This is an instrument that allows one to observe signal voltages that are constantly varying and it presented as a two dimensional graph of electrical potential difference using a vertical axis as a function of the horizontal axis or time. Signals such as sound can be converted into voltage and they can then be displayed in such a manner. The signals are usually periodic and they repeat constantly, and this means that several samples of the signal vary with time, and are displayed as a picture.
Digital Oscilloscope is used to observe the electrical signals wave shape, and they are calibrated such that they can read time and voltage. This allows us to measure peak-to-peak voltage of waveforms, their frequency and the time in between each pulse. The time a signal takes to reach the peak of the wave can also be measured and the timing of a number of signals that are related can also be measured.
Digital Oscilloscope is used in the scientific community, and this includes medicine, engineering as well as in the telecommunications industry. This is a general purpose instrument that is used to maintain electronic equipment and it is also used in laboratory work. A special purpose oscilloscope can be used for analyzing vehicle ignition systems or it can be used as an electrocardiogram to display the heartbeats waveform. Computer software for sound is what allows the sounds you are hearing to become displayed on a screen by the Digital Oscilloscope.
Before the instrument was developed, cathode ray tubes were used to display the signals, and this is the reason why the instrument was known as a CRO. The CRO was later replaced by the Digital Oscilloscope and it has a thin panel display, a fast conversion from analog to digital and it also has a digital signal processor. A digital storage oscilloscope that did not have an integrated display is available at a much lower cost, and the waveforms are processed with a general purpose digital computer.
The Digital Oscilloscope is divided into 4 sections, and it includes a display, vertical and horizontal controls and the trigger controls. The display unit is usually a cathode ray tube or an LCD panel, and in addition to the screen, some display sections are also equipped with 3 basic controls, a focus knob, the intensity knob as well as a knob for finding the beam.
