1 For Your Safety
The R&S OSP is designated for use in industrial, administrative, and laboratory
environments. Use the R&S OSP only for its designated purpose. Observe the
safety and usage instructions documented in the user manual, as well as operat-
ing conditions and performance limits stated in the data sheet.
The product documentation helps you to use the R&S OSP safely and efficiently.
Keep the product documentation in a safe place and pass it on to the subsequent
users.
Safety information is part of the product documentation. It warns you about the
potential dangers and gives instructions how to prevent personal injury or dam-
age caused by dangerous situations. Safety information is provided as follows:
●In the "Basic Safety Instructions", safety issues are grouped according to sub-
jects. For example, one subject is electrical safety. The "Basic Safety Instruc-
tions" are delivered with the R&S OSP in different languages in print.
●Throughout the documentation, safety instructions are provided when you
need to take care during setup or operation. Always read the safety instruc-
tions carefully. Make sure to comply fully with them. Do not take risks and do
not underestimate the potential danger of small details such as a damaged
power cable.
Restrictions on opening a switch unit
Opening an R&S OSP switch unit can lead to personal injury and instru-
ment damage.
To avoid these risks, do not open your switch unit.
If opening is required for mounting a module, let Rohde & Schwarz service
personnel mount this module.
If opening is not required for mounting a module, follow the mounting
instruction in the User Manual.

Risk of injury due to disregarding safety information
Observe the information on appropriate operating conditions provided in the
data sheet to prevent personal injury or damage to the instrument. Read
and observe the basic safety instructions provided with the instrument, in
addition to the safety instructions in the following sections.
Do not open the instrument casing, except for exchanging a hardware
option module, as described in the User Manual.
Risk of instrument damage due to inappropriate operating conditions
Specific operating conditions are required to ensure accurate measure-
ments and to avoid damage to the instrument. Observe the information on
appropriate operating conditions provided in the basic safety instructions
and the instrument's data sheet.
Risk of electrostatic discharge (ESD)
Electrostatic discharge (ESD) can damage the electronic components of the
instrument and the device under test (DUT).
A risk of damage due to ESD is typically limited to switch units that are
equipped with hardware options with one or more of the following features:
●Digital input or output ports (I/O ports)
●Solid-state relays (SSR)
●Integrated amplifiers in special modules that are delivered as part of a
test system
ESD is most likely to occur when you connect or disconnect a cable to one
of the switch unit's connectors. To prevent ESD, use a wrist strap and cord
and connect yourself to the ground, or use a conductive floor mat and heel
strap combination.
For details, refer to the basic safety instructions delivered as a printed bro-
chure with the instrument.

Risk of instrument damage during operation
An unsuitable operating site or test setup can damage the switch unit and
connected devices. Ensure the following operating conditions before you
switch on the switch unit:
●All fan openings are unobstructed and the airflow perforations are unim-
peded. The minimum distance from the wall is 10 cm.
●The instrument is dry and shows no sign of condensation.
●The instrument is positioned as described in the following sections.
●The ambient temperature does not exceed the range specified in the
data sheet.
Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation
concept to ensure that the instruments do not overheat. Insufficient airflow
for a longer period can disturb the operation and even cause damage.
EMI impact on measurement results
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated electromagnetic interference (EMI):
●Use suitable shielded cables of high quality. For example, use double-
shielded RF, LAN and HDMI cables.
Note: USB cables are of varying and often poor quality. Therefore, con-
sider the quality of each individual USB cable.
●Always terminate open cable ends.
●Note the EMC classification in the data sheet.

1.1 SSR Failsafe Concept
SSRs are intended for high-frequency and high-speed switching, but their semi-
conductor elements are damaged easily by excess current, voltage peaks or a
short circuit. If there is a malfunction, the SSR cannot switch off a connected load.
Hence, inappropriate conditions or usage can damage SSRs or connected com-
ponents and lead to associated problems.
Risk of injury and damage due to inappropriate SSR relay usage
Solid-state relays (SSRs) require a dedicated concept for failsafe operation.
If you do not implement such a concept in a competent manner, the relay
can fail in securely switching off the load. This failure can lead to a risk of
personal injury and damage of equipment.
To prevent this risk, avoid excess current, voltage peaks and short circuits.
Monostable vs. failsafe
The term "monostable relay" is often considered to be equivalent with the
term "failsafe relay", but this interpretation is misleading:
●Failsafe means, that the relay is designed to cause minimum or no harm
if there is a failure. To realize this goal, the relay must switch off a load
connected to its NO terminal (normally open), when the control voltage
is lost.
●Monostable means, that with no control voltage applied, the relay auto-
matically falls back to its "stable" default state. In this state, the C termi-
nal (common) is either connected to the NC terminal (normally connec-
ted, typically in SPDT switches) or not connected to any terminal (typi-
cally in drum switches).
– Monostable electromechanical relays are failsafe by their mechanical
design: With no voltage applied, a spring load brings back the switch
to its default NC state (or to no connection at all).
– On the contrary, monostable solid-state relays are not inherently
failsafe: Without any voltage applied, the relay quits functioning.
Hence, if the control voltage is lost, SSRs still require the presence
of a supply voltage for switching to the default sate.

2 Key Features
The R&S OSP is a highly flexible, modular switch and control platform. Each
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 master/slave configuration
●Optional installation of several remotely controlled satellite units (see p. 22)
●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 gen-
eration R&S OSP120/130/150

Backward compatibility details
●The new switch units R&S OSP220/230/320 are mechanically and elec-
trically fully compatible with all legacy standard hardware modules and
new modules, described in the User Manual
●The new firmware is also compatible with all these modules
However, the following limitations in compatibility apply:
●In a master-slave setup, you cannot mix legacy switch units with new
switch units. Differences in communication prevent a combination of the
two generations: The legacy switch units were interconnected by a
CAN-bus system, while the new switch units are interconnected via
Ethernet (LAN).
●Consequently, also the commands for configuring a master-slave setup
of new switch units differ from the commands for the legacy units.
●The new firmware addresses the modules by their connectors M01 to
M16 in a switch unit.
– In setting commands, the firmware alternatively accepts addressing
the modules by A11 A12 or A13, according to the 3 module connec-
tor buses in a legacy switch unit.
– In query commands, the firmware per default returns module num-
bers in Mxx format. However, you can use the command
CONFigure:COMPatible[:MODE] to let the firmware return mod-
ule numbers in A1x format, according to the legacy syntax. Refer to
the User Manual for details on this command.
As the legacy units had 3 module connectors, only, numbers beyond
A11, A12 and A13 make no sense, although the new module (connec-
tor) numbers run up to M16.
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.
Note that switch units are no measurement instruments. They support effi-
cient working with test and measurement setups, but switch units never dis-
play any measurement results or power levels.
