As with all practical instruments, oscilloscopes do not respond equally to all possible input frequencies. The range of sinusoid frequencies an oscilloscope can usefully display is referred to as its bandwidth. Bandwidth applies primarily to the Y-axis, though the X-axis sweeps must be fast enough to show the highest-frequency waveforms.
Tektronix 7854 oscilloscope with curve tracer and time-domain reflectometer plug-ins. Lower module is a mainframe of the series Tektronix TM500 and has a digital voltmeter, a digital counter, an old WWVB frequency standard receiver with phase comparator, and function generator.
A hand held oscilloscope is usually a real-time oscilloscope, using a monochrome or color liquid crystal display for its display. Due to the rise in the prevalence of PCs, PC-based oscilloscopes have been becoming more common. The PC platform can be part of a standalone oscilloscope or as a standalone PC in combination with an external ...
A PC-based oscilloscope is a type of digital oscilloscope which relies on a standard PC platform for waveform display and instrument control. In general, there are two types of PC-based oscilloscopes Standalone oscilloscopes which contain an internal PC platform (PC mainboard) – common with upper mid-range and high-end oscilloscopes
To the casual observer, a spectrum analyzer looks like an oscilloscope, which plots amplitude on the vertical axis but time on the horizontal axis. In fact, some lab instruments can function either as an oscilloscope or a spectrum analyzer.
An oscilloscope generally receives three channels of varying (or oscillating) voltage as input and displays this information on a cathode ray tube. The oscilloscope amplifies the input voltages and sends them into two deflection magnets and to the electron gun producing a spot on the screen. One magnet displaces the spot horizontally, the other ...
A Tektronix TDS210 digital oscilloscope. A digital storage oscilloscope (DSO) is an oscilloscope which stores and analyses the input signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides. [1]
A typical radar system broadcasts a short pulse of radio signal and then listens for echoes from distant objects. As the signal travels at the speed of light and has to travel to the target object and back, the distance to the target can be determined by measuring the delay between the broadcast and reception, multiplying the speed of light by that time, and then dividing by two (there and ...
