Data Communications refers to the transmission of digital information over a communication channel. The data transmission types include either parallel or serial type transfer. When data transmission is required over long haul, it is feasible to use serial type transfer as it allows high data rates with cost efficiency. Serialized data can be of asynchronous or synchronous in nature.
Different transmission mediums have evolved over the years for transmitting data signals, either electrically, optically, or as radio waves. The selection of the transmission medium largely depend on the distance over which data signals needs to transferred, data rates, cost, and reliability.
The Datacom Analyzer is an optional board available with GL’s tProbe™ T1 E1 Analyzer USB Unit and is designed for the service installation, verification, and maintenance of data communications and telecom equipments. It provides a software selectable interface to emulate DTE, DCE and monitor the data communication lines for synchronous (sync), and asynchronous (async) modes of operation. The analyzer supports BER testing in ASYNC or SYNC mode. In SYNC mode, the Rx and Tx clock sources are either internal or external and triggered with rising or falling edge detection.
The Datacom Analyzer supports V.24, V.35, V.36, RS-449, RS-485, EIA-530 and EIA-530A interfaces and can be configured as DTE or DCE to test Channel Service Unit (CSU) and Data Service Unit (DSU) entities used to create point-to-point multi-port applications. Its main features include...
