The R&S®OSP is a high-performance switch platform from Rohde & Schwarz. It
facilitates RF tests by eliminating the need to rearrange coaxial cable connections
repeatedly during measurements. Instead, the application-specific modules in the
base unit automatically switch the required signal paths.
This document describes the following R&S®OSP base units with firmware version 2.30 and later:
●
R&S®OSP220 Base Unit 2HU without Touchscreen (order no. 1528.3105.02)
●
R&S®OSP230 Base Unit 2HU with Touchscreen (order no. 1528.3105.03)

If stacking is possible, keep in mind that a stack of products can fall over and
cause injury.
If you mount products in a rack, ensure that the rack has sufficient load capacity
and stability. Observe the specifications of the rack manufacturer. Always install
the products from the bottom shelf to the top shelf so that the rack stands
securely. Secure the product so that it cannot fall off the rack.

Safety and regulatory information
Safety considerations for SSRs
1.6 Safety considerations for SSRs
Risk of injury and damage due to inappropriate SSR usage
At power loss, solid-state relays (SSRs) have no defined switching state. Hence,
other than an electromechanical monostable relay, if there is a malfunction (for
example, missing supply voltage), typically the SSR ports go to a high-impedance
state. But the relay does not actively switch off a connected load. This failure can
lead to a risk of personal injury and damage of equipment.
To prevent this risk, you must implement a dedicated concept for failsafe operation of your system in a competent manner.
Risk of damage due to inappropriate SSR usage
Solid-state relays (SSRs) are intended for high-frequency and high-speed switching, but their semiconductor elements are damaged easily by excess current, voltage peaks or a short circuit. Hence, inappropriate conditions or usage can damage SSRs or connected components and lead to associated problems.
To prevent this risk, avoid excess current, voltage peaks and short circuits.
Risk of SSR damage due to inappropriate operating conditions
Solid-state relays (SSRs) for RF applications are intended for switching low powers. To avoid damage due to overload, refer to the operating conditions according
to the data sheet.
Monostable vs. failsafe
Without power, a solid-state relay (SSR) quits operating as a switch:
●
It is in a non-defined high-impedance state
●
It does not have any stable switching state
Sometimes, SSRs are considered as behaving like a monostable relay. And the
term "monostable relay" is often considered to be equivalent with the term "failsafe relay". However, this interpretation is misleading.
For more information, refer to the user manual.

switch unit can be equipped with several application-specific switch modules.
The platform meets the requirements of diverse test scenarios in production, labs
and development environments. Scenarios range from desktop configurations for
laboratory measurements to complex, rack-integrated test systems.
The R&S OSP220/230/320 described in this manual are the second generation of
switch units from Rohde & Schwarz, replacing the R&S OSP120/130/150.
Outstanding key features are:
●
5 to 10 module slots and up to 16 module buses provide maximum flexibility
●
Fast setup of test and measurement configurations
●
Replace complex wirings by a single switch and control platform
●
Easy interconnection configuration of primary and secondary switch units
●
Optional installation of several remotely controlled satellite units (see p. 29)
●
Reliable measurements and reproducible tests
●
Automation for cost-efficient test sequences
●
Electromechanical relay modules up to 67 GHz
●
Solid-state relay modules with switching and settling times down to the µs
range
●
Backward compatible to all standard modules of the previous switch unit generation R&S OSP120/130/150, as described in the user manual
The available switch modules are described in the user manual.
For a detailed specification of the R&S OSP, refer to the data sheet, available for
download at www.rohde-schwarz.com/brochure-datasheet/osp-n.
Note that switch units are no measurement instruments. They support efficient working with test and measurement setups, but switch units do not display measurement results or power levels.
