The N5103A high speed serial interface card is a high-performance, digital, bi-directional CPRI interface with SFP connectors for 614.4, 1228.8 and 2457.6 Mbps link rates. It is used in conjunction with Keysight's N5101A Baseband Studio PCI card and the N5120A Baseband Studio for CPRI RE test software, to emulate an REC (radio equipment controller) to stimulate the RE for many performance tests.
This solution allows uplink test capabilities such as receiver sensitivity testing with real-time BER/BLER, modulation analysis, and data capture as well as downlink test capabilities such as multi-carrier W-CDMA signal and transmitter modulation analysis. It also enables control and management support of HDLC (high-level data link control).
