Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
“Wires” made of glass fibre used to transmit video, audio, voice, or data providing vastly wider bandwidth than standard coaxial cable.

Architecture used to maintain high data transfer rates over long distances. With FC-AL storage arrays can be separated by as much as 20 kilometers, connected by only one nonamplified Fibre Channel fibre optic link. In the dual-loop architecture, data transfer rates can reach 200 Mb/s. Another advantage is increased fault tolerance. In the unlikely event of a drive failure, port bypass circuits single out each failed drive and quickly route around it, with no limitation on the number of drives that can be bypassed.
Industry:Entertainment
A high-speed data link planned to run up to 2 Gbps on a fibre optic cable. A number of manufacturers are developing products to use the fibre Channel-Arbitrated Loop (FC-AL) serial storage interface at 1 Gbps so that storage devices such as hard discs can be connected.
Supports signalling rates from 132.8 Mbps to 1,062.5 Mbps, over a mixture of physical media including optical fiber, video coax, miniature coax, and shielded twisted pair wiring. The standard supports data transmission and framing protocols for the most popular channel and network standards including SCSI, HIPPI, Ethernet, Internet Protocol, and ATM.
Industry:Entertainment
Standards for a 100 Mbps local area network, based upon fibre optic or wired media configured as dual counter rotating token rings. This configuration provides a high level of fault tolerance by creating multiple connexion paths between nodes.
Connections can be established even if a ring is broken.

A) In interlaced scan systems, the information for one picture is divided up into two fields. Each field contains one-half of the lines required to produce the entire picture. Adjacent lines in the picture are in alternate fields. b) Half of the horizontal lines (262.5 in NTSC and 312.5 in PAL) needed to create a complete picture. c) One complete vertical scan of an image. In a progressive scanning system, all of the scanning lines comprising a frame also comprise a field. d) An area in a window in which you can type text. e) A television picture is produced by scanning the TV screen with an electron beam. One complete scan of the screen is called a field.
Two fields are required to make a complete picture, which is called a frame. The duration of a field is approximately 1/60 of a second in NTSC and 1/50 or 1/60 of a second in PAL. f) One half of a complete interlaced video picture (frame), containing all the odd or even scanning lines of the picture.
Industry:Entertainment
An alias caused by interlaced scanning. See also Interlace Artifacts.

Refers to the part of the signal at the end of each field that make the vertical retrace invisible. Also called vertical blanking.

When a CAV laserdisc is placed in the still frame mode, it continuously plays back two adjacent fields of information. There are no rules in the NTSC system stating that a complete video picture has to start on field 1 or field 2. Most of the video in this programme is field 1 dominant. There are two sections of the disc that are field 2 dominant. In the case of film translated to video, the start of a complete film picture changes from field 1 to field 2 about 6 times a second. There is a code in the vertical interval of the disc that tells the player on which field it can start displaying each of the disc’s still frames.
Industry:Entertainment
The rate at which one complete field is scanned, normally 59.94 times a second in NTSC or 50 times a second in PAL.
