RASTER SCAN WAVEFORMS DIGILENT SOFTWARE

Scanning pattern The beam position (sweeps) follow roughly a sawtooth wave. Thus, while the number of scan lines (vertical resolution) is unambiguously defined, the horizontal resolution is more approximate, according to how quickly the signal can change over the course of the scan line. Analog television has discrete scan lines (discrete vertical resolution), but does not have discrete pixels (horizontal resolution) – it instead varies the signal continuously over the scan line. This ordering of pixels by rows is known as raster order, or raster scan order. Each scan line can be transmitted in the form of an analog signal as it is read from the video source, as in television systems, or can be further divided into discrete pixels for processing in a computer system. In a raster scan, an image is subdivided into a sequence of (usually horizontal) strips known as ' scan lines'. Unsourced material may be challenged and removed.

This memory area holds the values for each pixel on the screen. In most modern graphics cards the data to be drawn is stored internally in an area of semiconductor memory called the framebuffer. Although often a great deal faster, it is similar in the most general sense to how one's gaze travels when one reads lines of text. It is a systematic process of covering the area progressively, one line at a time. The pattern left by the lines of a rake, when drawn straight, resembles the parallel lines of a raster: this line-by-line scanning is what creates a raster. The word raster comes from the Latin word rastrum (a rake), which is derived from radere (to scrape) see also rastrum, an instrument for drawing musical staff lines. By analogy, the term is used for raster graphics, the pattern of image storage and transmission used in most computer bitmap image systems.

Several modulation modes are also available (gate, burst and scan modes) that can be triggered by internal or external sources. Other features are available, such as pulse generation with a 100ps wide resolution with a 30ps lower jitter and variable rise and fall times. Software for editing and generating arbitrary waveforms, running on a PC, is supplied with the instrument. These instruments can generate various standard waveforms as well as custom signals at sampling rates up to 800 MS/s. They are also distinguished by their phase control capability to within 0.001 degrees. These generators are equipped with two channels which can operate in independent, coupled or tracking mode. Both standard signal and arbitrary waveform generators in the TGF3000 range can deliver signals up to frequencies of 80 and 160 MHz.RS Components (RS), the brand of Electrocomponents, distributor of electronic components, industrial equipment and test and measurement instruments, announces the availability in its catalogue of two arbitrary function and signal generators from the TGF3000 range of Aim-TTi (Thurlby Thandar Instruments) with which RS has been a partner for 40 years.
