New Modular RF Switch for a Wide Range of Test Scenarios


R&S OSP open switch and control platform allows users to combine a wide variety of switch and control modules to form a customized control center for their test setup

New technologies such as 5G and state-of-the-art radar technology’s test setups require switch and control technology with large frequency ranges and short switching times. So, to address this need, Rohde & Schwarz has presented 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:

  • Optional R&S OSP-K100 trigger function
  • Hardware-based switching of predefined paths is possible using the external trigger inputs and outputs.
  • Allows users to reduce switching times even further compared to a LAN based trigger.
  • R&S OSP320 provides an additional digital address input on its rear panel for direct triggering of predefined paths.

New operating concept

For R&S OSP configuration separate software is not needed. The display automatically adjusts to the size of the screen. Controlling PC with large monitor displays several switch modules at the same time, simplifying the complicated interconnections.

Path control allows users to combine the relay switches of one or more R&S OSPs to define paths. These paths can be pre-configured in virtual mode without having all devices and modules available.

Virtually unlimited expandability

The new R&S OSP product family starts with the three R&S OSP220/230/320 units. These units have five, six or ten module slots on both front and rear panel. This simplifies cable placing, as customers can themselves place the cabling based on their specific requirements. The module slots can be combined to form larger application-specific modules.

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 new generation of the R&S OSP switch and control platform is now available from Rohde & Schwarz.
