Overview:
An oscilloscope or scope is an electronic measuring instrument that creates a visible two-dimensional graph of one or more electrical potential differences. The horizontal axis of the display normally represents time, making the instrument useful for displaying periodic signals. The vertical axis usually shows voltage. The display is caused by a "spot" that periodically "sweeps" the screen from left to right.
Digital storage oscilloscope
Oscilloscope software running in WindowsThe digital storage oscilloscope, or DSO for short, is now the preferred type for most industrial applications, although simple analogue CROs are still used by hobbyists. It replaces the unreliable storage method used in analogue storage scopes with digital memory, which can store data as long as required without degradation. It also allows complex processing of the signal by high-speed digital signal processing circuits.
The vertical input, instead of driving the vertical amplifier, is digitised by an analog to digital converter to create a data set that is stored in the memory of a microprocessor. The data set is processed and then sent to the display, which in early DSOs was a cathode ray tube, but is now more likely to be an LCD flat panel. DSOs with colour LCD displays are common. The data set can be sent over a LAN or a WAN for processing or archiving. The scope's own signal analysis software can extract many useful time-domain features (e.g. rise time, pulse width, amplitude), frequency spectra, histograms and statistics, persistence maps, and a large number of parameters meaningful to engineers in specialized fields such as telecommunications, disk drive analysis and power electronics.
Example usage
The classic use of a scope is to diagnose a failing piece of
electronic equipment. In a radio, for example, one looks at the
schematic and tries to locate the connections between stages (e.g.
electronic mixers, electronic oscillators, amplifiers).
Then one puts the scope's ground on the circuit's ground, and
the probe of the scope on a connection between two of the stages in
the middle of the train of stages.
When the expected signal is absent, one knows that some
preceding stage of the electronics has failed. Since most failures
occur because of a single faulty component, each measurement can
prove that half of the stages of a complex piece of equipment
either work, or probably did not cause the fault.
Once the failing stage is found, further probing of the
defective stage can usually tell a skilled technician exactly which
component is broken. Once the technician replaces the component,
the unit can be restored to service, or at least the next fault can
be isolated.
Another use is to check newly designed circuitry. Very often a
newly-designed circuit will misbehave because of bad voltage
levels, electrical noise or design errors. Digital electronics
usually operates from a clock, so a dual-trace scope is needed to
check digital circuits. "Storage scopes" are helpful for
"capturing" rare electronic events that cause defective
operation.
Another use is for software engineers who must program
electronics. Often a scope is the only way to see if the software
is running the electronics properly.
