An oscilloscope is a device that captures an input voltage signal and converts it to a correctly scaled voltage versus time waveform that is displayed on a scaled grid. The oscilloscope has a triggering circuit that defines when the input signal should be captured and displayed, and a variable gain front end that permits (vertical voltage) signal adjustment to accept a wide range of input signal amplitudes. A horizontal (timebase or sweep) adjustment defines the period of time to acquire the signal.
Many will claim to have invented the analog oscilloscope, but Tektronix can rightly claim to have invented the first triggered-sweep (analog) oscilloscope, which vastly improved the usefulness and versatility of the instrument.
Walter LeCroy and his design team at LeCroy Corporation (now Teledyne LeCroy) in 1985 released the first digital storage oscilloscope (DSO, or now just referred to as a digital oscilloscope) – named the Model 9400 – that replicated and improved on the features and capabilities of the analog oscilloscopes in use up to that time. The Model 9400 had bandwidth (125 MHz) equivalent to what was available in an analog oscilloscope (at the time) and could continuously capture a signal for a long period of time using 32,000 sample points (at the time, an amazingly long acquisition record length). A tenuous claim could be made that LeCroy’s WD2000 Waveform Digitizer (launched in 1971) was the first digital storage oscilloscope, but the record length was limited to 20 sample points and the architecture could not easily scale to longer record lengths.

An analog oscilloscope uses a cathode-ray tube (CRT) to display a voltage vs. time variation of an electrical signal. The CRT beam sweeps across the CRT for a defined period of time, beginning with a location defined by a trigger circuit. The (horizontal) time period is referred to as the (beam) sweep. A variable gain front-end amplifier sets the maximum vertical deflection of the CRT beam during the sweep. The CRT beam intensity would decay rapidly after the sweep, so the analog oscilloscope was very useful for viewing repetitive signals but less useful for viewing intermittent signals. A recording device, such as a polaroid camera, was often employed to take a picture of the CRT synchronized with an intermittent trigger event.
A digital oscilloscope uses an analog-to-digital converter (ADC) to vertically sample, at discrete time intervals, an analog input signal and then convert the analog input signal to digital sample points at defined quantization levels. When the digital sample points are connected together, they faithfully represent the analog signal. Digital oscilloscopes are characterized by the number of vertical levels in the ADC, described as N bits with 2N defining the maximum possible number of discrete vertical quantization levels that can be differentiated for each sample point. Each sample point is stored in a memory buffer for display or further mathematical processing of some sort.
A digital storage oscilloscope is just another term for a digital oscilloscope, reflecting that the sample points are stored in a memory buffer.
An analog oscilloscope uses a cathode-ray tube (CRT) to display a phosphor trace on the CRT, with the trace displaying a continuous voltage vs. time waveform consistent with the electrical input signal and the trace intensity quickly decaying over time. A digital oscilloscope converts the analog electrical input signal into digital sample points that, when connected together, correctly reproduce the analog waveform, and the reconstructed waveform is displayed on an LCD display, with the digital sample points available to be further processed to make measurements or calculate math functions.
