Digital sampling oscilloscopes operate on the same principle as analog sampling oscilloscopes and, like their analog counterparts, are of great use when analyzing high-frequency signals; that is, repetitive signals whose frequencies are higher than the oscilloscope's sampling rate.
A Tektronix model 475A portable analog oscilloscope, a typical instrument of the late 1970s Oscilloscope cathode-ray tube, the left square-shaped end would be the blue screen in the upper device when built in. Typical display of an analog oscilloscope measuring a sine wave signal with 10 kHz. From the grid inherent to the screen together with ...
A Tektronix 465 portable analog oscilloscope is a typical instrument of the late 1970s. In the 1960s Tektronix introduced the relatively compact 450 series of portable oscilloscopes, starting with the 50 MHz 453. The 453 was superseded by the 454. There was also a 422 15 MHz AC/DC portable made. [1]
In telecommunications, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input (y-axis), while the data rate is used to trigger the horizontal sweep (x-axis). It is so called because, for several types of coding, the pattern ...
Waveform monitor in 2-line mode, showing color bars.. A waveform monitor is a special type of oscilloscope used in television production applications. It is typically used to measure and display the level, or voltage, of a video signal with respect to time.
The BK Precision model 4078 Dual Channel Arbitrary Waveform Generator uses direct digital synthesis to generate waveforms up to 400,000 points HAMEG HMF 2550 digital AWG under an oscilloscope displaying the generated waveform. An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.
Analog television systems using CRTs had two time bases, one for deflecting the beam horizontally in a rapid movement, and another pulling it down the screen 60 times per second. Oscilloscopes often have several time bases, but these may be more flexible function generators able to produce many waveforms as well as a simple time base.
A spectrum analyzer is also used to determine, by direct observation, the bandwidth of a digital or analog signal. A spectrum analyzer interface is a device that connects to a wireless receiver or a personal computer to allow visual detection and analysis of electromagnetic signals over a defined band of frequencies.
