DS2172TN+

The DS2172 Bit Error Rate Tester (BERT) is a software programmable test pattern generator, receiver, and analyzer capable of meeting the most stringent error performance requirements of digital transmission facilities. Two categories of test pattern generation (Pseudo-random and Repetitive) conform to CCITT/ITU O.151, O.152, O.153, and O.161 standards.
The DS2172 operates at clock rates ranging from DC to 52 MHz. This wide range of operating frequency allows the DS2172 to be used in existing and future test equipment, transmission facilities, switching equipment, multiplexers, DACs, Routers, Bridges, CSUs, DSUs, and CPE equipment.
