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 ver-
sion 2.10 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)
●R&S®OSP320 Base Unit 3HU without Touchscreen (order no. 1528.3111.02)
●R&S®OSP-B200S2 Satellite 2HU for Base Units (order no. 1528.3134.02/.04)
For all optionally available standard switch modules, refer to the user manual,

Setting up the product
Always place the product on a stable, flat and level surface with the bottom of the
product facing down. If the product is designed for different positions, secure the
product so that it cannot fall over.
If the product has foldable feet, always fold the feet completely in or out to ensure
stability. The feet can collapse if they are not folded out completely or if the prod-
uct is moved without lifting it. The foldable feet are designed to carry the weight of
the product, but not an extra load.
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.
Connecting to power
The product is an overvoltage category II product and has to be connected to a
fixed installation used to supply energy-consuming equipment such as household
appliances and similar loads. Be aware that electrically powered products have
risks, such as electric shock, fire, personal injury or even death.
Take the following measures for your safety:
●Before switching on the product, ensure that the voltage and frequency indica-
ted on the product match the available power source. If the power adapter
does not adjust automatically, set the correct value and check the rating of the
fuse.
●If a product has an exchangeable fuse, its type and characteristics are indica-
ted next to the fuse holder. Before changing the fuse, switch off the instrument
and disconnect it from the power source. How to change the fuse is described
in the product documentation.
●Only use the power cable delivered with the product. It complies with country-
specific safety requirements. Only insert the plug into an outlet with protective
conductor terminal.
●Only use intact cables and route them carefully so that they cannot be dam-
aged. Check the power cables regularly to ensure that they are undamaged.
Also ensure that nobody can trip over loose cables.

●If the product needs an external power supply, use the power supply that is
delivered with the product or that is recommended in the product documenta-
tion or a power supply that conforms to the country-specific regulations.
●Only connect the product to a power source with a fuse protection of maxi-
mum 20 A.
●Ensure that you can disconnect the product from the power source at any
time. Pull the power plug to disconnect the product. The power plug must be
easily accessible. If the product is integrated into a system that does not meet
these requirements, provide an easily accessible circuit breaker at the system
level.
Cleaning the product
Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind that
the casing is not waterproof. Do not use liquid cleaning agents.
Meaning of safety labels
Safety labels on the product warn against potential hazards.
Potential hazard
Read the product documentation to avoid personal injury or product damage.
Electrical hazard
Indicates live parts. Risk of electric shock, fire, personal injury or even death.
Hot surface
Do not touch. Risk of skin burns. Risk of fire.
Protective conductor terminal
Connect this terminal to a grounded external conductor or to protective ground. This
protects you against electric shock should an electric problem occur.
1.3 Labels on the Product
Labels on the casing inform about:

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 opera-
tion 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 switch-
ing, but their semiconductor elements are damaged easily by excess current, volt-
age peaks or a short circuit. Hence, inappropriate conditions or usage can dam-
age 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 pow-
ers. 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 "fail-
safe relay". However, this interpretation is misleading.
For more information, refer to the user manual.
