Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Repeaters are transparent devices used to interconnect segments of an extended network with identical protocols and speeds at the physical layer (OSI layer 1). An example of a repeater connexion would be the linkage of two carrier sense multiple access/collision detection (CSMA/CD) segments within a network.
Industry:Software
Device designed to generate special effects. The simplest devices process a single video signal, change its color, generate sepia tones, invert the picture to a negative, posterize the image, and fade or break up the image into various patterns. More sophisticated equipment uses several video sources, computer-generated graphics and sophisticated animation with digital effects.
Industry:Software
The relationship between video input to the monitor and the luminance of the CRT. Monitors are required to conform to a narrower range of performance specifications than is expected of commercial receivers. Confirming these tighter tolerances requires attention to measurement details since, for example, the luminance may vary if different areas of the tube face are selected. Light output is routinely measured in the centre of large, uniform “patches” or windows.
Since there is significant “bleeding” of light within a CRT face, the monitor transfer function also decreases with decreasing size of the windows (it is thus reduced for fine detail) and with increasing video level of the raster surrounding the windows.

A) For animation, many 3D systems fix the viewer’s location at a specified distance from the viewing screen. Currently, PictureMaker is one of these. In such systems, the database is moved relative to the viewer.
The set of motions that accomplish any particular view of the world is called its “orientation.” Using the three coordinate axes as references, we can translate (shuffle on a plane) and rotate objects to create new views.
During animation, we change the amounts of these motions. A set of numbers describes orientation: x-trans, y-trans, z-trans, x-rot, y-rot, z-rot. b) A direction of presentation affecting resolution requirements. Horizontal lines become vertical lines when their orientation is rotated by 90 degrees; a pattern of dots appearing to be in horizontal and vertical rows may not appear to be diagonally aligned when its orientation is rotated 45 degrees due to characteristics of the human visual system.
Industry:Software
A generic term for one of the elementary streams or other data streams that may be included in the program.
Industry:Software
The recording of a digital data stream onto a single recording track. With multitrack recorders, multiple streams can be recorded as long as each stream is recorded on a separate track. There is no requirements that multiple streams have a common synchronous clock nor is it required that the multiple streams be the same recording code.
Industry:Software
The standard operating system software and tools that come on the system disc and on the tape or DC-ROM that you use in the event of a system crash.
Industry:Software
A device that stabilises the composite video signal, regenerates the synchronising pulses, and can make other adjustments to the video signal.
Industry:Software
The phase locked loop (PLL) is central to the operation of frequency and phase stable circuitry. The function of the PLL is to provide a frequency/phase stable signal that is based on an input reference signal.
Industry:Software
One method of hardware zooming is accomplished by multiplying the number of pixels and is known as pixel replication or simply, replication. Because replication increases the size of pixels and the effect is a blocky picture when zoomed, interpolation is a preferred technology where intermediate pixels are approximated causing less block video.
