Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The PLUGE signal was designed for rapid and accurate adjustment of the black level, reference and, hence, the luminance range, display. It provides adjacent vertical bars, one at black level, reference and continuous bars slightly above and slightly below that reference. Following initial development by the BBC, CCIR now recognises at least eight versions. SMPTE EG 1-1990 includes a variant in which the black level, reference is flanked by bars at –4 IRE and +4 IRE. When the –4 IRE merges into the black level, reference bar, but the +4 IRE bar is distinguishable, black level, reference is correctly set. A white patch is included at peak white, to define IRE 100, and the luminance range, display CRT.
Industry:Software
The amount of resolvable detail in the horizontal direction in a picture. It is usually expressed as the number of distinct vertical lines, alternately black and white, which can be seen in three-quarters of the width of the picture. This information usually is derived by observation of the vertical wedge of a test pattern. A picture which is sharp and clear and shows small details has a good, or high resolution. If the picture is soft and blurred and small details are indistinct it has poor, or low resolution.
Horizontal resolution depends upon the high-frequency amplitude and phase response of the pickup equipment, the transmission medium and the picture monitor, as well as the size of the scanning spots.
Industry:Software
A form of buckling in which the tape pack is deformed into a shape which approximates a polygon.
Industry:Software
Broadcast station that rebroadcasts signals of other stations without originating its own programming.
Industry:Software
The magnitude of the reproduced signal voltage, usually measured at the output of the reproduce amplifier. The output of an audio or instrumentation tape is normally specified in terms of the maximum output that can be obtained for a given amount of harmonic distortion, and is expressed in dB relative to the output that can be obtained from a reference tape under the same conditions.
Industry:Software
Set of syntax rules defining exchange of data including items such as timing, format, sequencing, error checking, etc.
Industry:Software
An electrical device controlling the speed of a moving or rotating device such as a capstan/pinchroller rotating speed.
Industry:Software
The turntable which takes up the tape after it passes by the heads.
Industry:Software
An electronic component consisting of a tuner, an R modulator, and a video deck used for recording and playback of a videocassette.
Industry:Software
Refers to a cathode-ray tube and its associated circuits, arranged to view a television picture.
