Features & benefits

Modular, reliable, cost-efficient

Essential for reproducible measurements

The modularity of the R&S®OSP family speeds up test and measurement configurations for applications in production, test labs and development. Implementing complex wiring with a single switch and control platform is essential for reliable and reproducible measurements that can be automated for cost-efficient test sequences.

Compact, secure and flexible

Different models in up to 10 flexible module slots

R&S®OSP units are accommodated in a compact 19" cabinet of two or three rack units. 
The powerful CPU and LINUX operating system provide maximum flexibility for controlling switch and control modules, enabling use of  internal and external interfaces. 
The module slots on the rear and front of each unit can be integrated into one, extra-wide triple or double module slot to accept larger modules with an extended range of functions.

Powerful control and RF relay modules

Electromechanical relays up to 67 GHz

Options include:

  • Universal electromechanical RF relay modules with N relays (from DC to 12.4 GHz),
  • Electromechanical RF relay modules from DC to 18 GHz, 26.5 GHz, 40 GHz, 50 GHz and 67 GHz
  • Solid-state relay (SSR) modules (up to 43.5 GHz), digital I/O and multiplexer modules
  • Special system modules make implementation of EMS and other test systems easier.
  • Auxiliary modules such as RF attenuators can be easily combined with relay modules for advanced applications.
  • Module kit for versatile off-the-shelf customization

Expandable system configurations

Easy system integration and virtually unlimited expandability

All R&S®OSP models can be combined via Ethernet in a local, corporate or global network with a primary/secondary configuration. Existing R&S®OSP systems can be expanded to meet future requirements.
The compact R&S®OSP‑B200S2 satellite box can be used for remote operation as an alternative to networking multiple R&S®OSP units. The satellite box moves RF switching and controlling closer to the DUT or antennas,. reducing the number of long RF cables required, improving RF performance of the setup and saving costs.

Intuitive operation

Easy manual operation and remote control using web interface

R&S®OSP models come with a built-in web interface for local operation or remote control from a PC or laptop with browser. When control is browser based, the displayed content resolution is automatically adjusted to the monitor screen size.
All R&S®OSP models can be controlled with a keyboard and mouse and an external HDMITM monitor.

Path control

Efficient manual operation or programming

  • Relay switching states are combined to define paths, simplifying control and programming for complex wiring configurations.
  • Being able to copy and paste the syntax of manually defined paths into SCPI commands makes for very efficient SCPI programming.

Trigger function

Faster Switching

External triggers control switching processes more precisely and make them up to 1000 times faster when solid-state relays are used. Key trigger function features

  • Very fast OSP module switching with solid state relays (SSR), up to 1000 times faster than LAN
  • Hardware controlled switching of all switching elements by
    - external measurement devices
    - external hardware of a measurement setup
  • Precise and reproducible switching in line with the trigger signal
  • Four different trigger types: single, toggle, sequenced and addressed
  • Trigger can be configured via SCPI and touchscreen
  • Manual trigger for debugging without ext. trigger signal
  • The GUI displays the minimal trigger interval/maximum trigger frequency for the configuration
