Modern communication standards like cellular, WiFi, ISM and Bluetooth need bidirectional signal transmissions, independent of the multiplex method: TDD (Time Domain Division) or FDD (Frequency Domain Division). BSDU-4X4ER is right solution to route communication testers to DUTs (Devices under Test) or transceivers to antennas.
It offers 4 full parallel bidirectional signal paths.
The switching elements in the BSWM-4X4ER are solid state types. This ensures the short switching time, a huge number of switching cycles with a minimum in maintenance. The RF ports are non-reflective. Also in the case of an open switch the RF port of the matrix is terminated with 50 ohms.
To avoid unwanted signal couplings between the channels BSWM-4X4ER has high channel isolation. Adjacent channels with strong and weak signals have no influence to each other.
The device can be controlled either via the remote interfaces LAN and USB (SCPI-based ASCII-commands) or local via a MMI (Man Machine Interface) on the front panel. Additional BSWM-4X4ER offers a web based, user friendly GUI (Graphical User Interface).
