Multiplexer; Like a scan configuration, multiplex switching can be used to connect one instrument to multiple devices (1:N) or multiple instruments to a single device (N:1), but it offers much more flexibility than the scanner configuration because it permits multiple simultaneous connections and both sequential and non-sequential switch closures.
The content could be general descriptive information, information on wiring and connections, test procedures, or piece-part replacement and repair information. The BSP documents were produced in primarily two formats, 8 1/2"x11" pages for use in office environments, and in a small, portable format (4" x 6 7/8") for use by installers on the job ...
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location. A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF ( radio frequency ) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT).
The DMS-100 is a member of the Digital Multiplex System (DMS) product line of telephone exchange switches manufactured by Northern Telecom. Designed during the 1970s and released in 1979, it can control 100,000 telephone lines. [1] The purpose of the DMS-100 Switch is to provide local service and connections to the PSTN public
First, the switch matrix receives the data bus signals, then provides the proper switching and signal conditioning for the signals before feeding the signals to the test and measurement instruments. This custom switch matrix would employ 14 EM switches and a number of different signal conditioners including: power splitters, amplifiers, mixers ...
Some have electrical connectors, and others have optical fiber connectors. A breakout box serves as a troubleshooting tool to determine the wiring of an electrical connector interface on a networking device or computer. Typically, a breakout box is inserted between two electrical devices to determine which signal or power interconnects are active.
The No. 1 Electronic Switching System Arranged with Data Features (No. 1 ESS ADF) was an adaptation of the Number One Electronic Switching System to create a store and forward message switching system. It used both single and multi-station lines for transmitting teletypewriter and data messages. It was created to respond to a growing need for ...
