Rohde & Schwarz presents new modular RF switch and control platform for a wide range of test scenarios
Test setups for new technologies such as 5G and state-of-the-art radar technology require switch and control technology with large frequency ranges and short switching times. To meet this requirement, Rohde & Schwarz has completely revised its platform and now presents the new R&S OSP220/230/320 units and the new R&S OSP-B200S2 satellite box.
The new generation offers special features such as the optional R&S OSP-K100 trigger function. Hardware-based switching of predefined paths is possible using the external trigger inputs and outputs. This allows users to reduce switching times even further compared to a LAN based trigger. Such short switching times are necessary, for example, to trigger the high-speed solid-state relays in antenna arrays and radar modules. The R&S OSP320 provides an additional digital address input on its rear panel for direct triggering of predefined paths.
New operating concept
Virtually unlimited expandability
Since previous R&S OSP modules can be used with the new R&S OSP generation, a comprehensive range of modules is available, including RF relays, electromechanical coaxial relays up to 67 GHz, solid-state relays and digital I/O and multiplexer modules. Customers can use the new switch and control unit as a desktop model for lab measurements or as a control center for complex rack-based test systems. Over a LAN, several R&S OSPs can be combined using a master/slave configuration to create a complex switch network of 20, 50 or more relays.
The compact R&S OSP-B200S2 satellite box enables remote operation, for example, in a shielded test chamber. The satellite box moves switch and control tasks closer to the DUT or the antennas. This reduces the number of long RF cables, improves the RF performance of the setup and saves money. Depending on the application, the satellite box is triggered using a serial electrical bus cable or a fiber-optic connection.
