Chapter 2.4, "Mounting a module", on page 41.
1.1.6 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.
Welcome
Safety and regulatory information
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.
See also "Monostable and bistable relays" on page 53.
See also "FS (open)*" on page 53.
See also "Off/on switching states of various relays" on page 330.

2.1.6 Considerations for test setups
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
NOTICE! Electrostatic discharge can damage the electronic components of the
►
product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
0025.2365.00
0086.4400.44
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
A risk of damage due to ESD is typically limited to switch units that are equipped with
modules that have 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
Preventing electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF, LAN and HDMI
cables.
Note: USB cables are of varying and often poor quality. Therefore, consider the
quality of each individual USB cable.
●
Always terminate open cable ends.
●
Note the EMC classification in the data sheet.
●
Ensure that connected external devices comply with EMC regulations.

R&S®OSP
Getting started
Preparing for use
Preventing overload on internal terminations
Overloading an electromechanical RF relay with internal port termination can damage
or destroy the relay.
The maximum load that the internal termination of one port can handle is approximately 1 W. However, if the relay has several terminated ports, their cumulative maximum load is less than the sum. For example, an SP6T relay with 6 internally terminated ports cannot handle 6 W, but typically 3 W, only.
To avoid the risk of damage due to overloading internal terminations, limit the load to
the "Max. termination power per relay" that is specified in the data sheet.
2.1.7 Connecting to power
The switch unit is equipped with an AC power supply connector and can be used with
different AC voltages. The R&S OSP adapts itself automatically to the voltage. Refer to
the data sheet for the voltage and frequency requirements. The AC power connector is
on the rear panel of the switch unit.
► Connect the R&S OSP to an AC power supply using the supplied power cable.
As the switch unit's assembly is in line with the specifications for safety class
EN61010, you must connect it only to an outlet that has a ground contact.
For replacing the fuses, refer to Chapter 12.1, "Replacing fuses", on page 315.
2.1.8 Connecting to LAN
The LAN connector (RJ45) of the R&S OSP is on its rear panel, shown in Figure 2-16.
Network environment
Before connecting the product to a local area network (LAN), consider the following:
●
Install the latest firmware to reduce security risks. See Chapter 12.3, "Firmware
update", on page 317.
●
For internet or remote access, use secured connections if applicable.
For example, use HTTPS, SFTP, FTPS instead of HTTP, FTP.
●
Ensure that the network settings comply with the security policies of your company.
Contact your local system administrator or IT department before connecting your
product to your company LAN.
●
When connected to the LAN, the product may potentially be accessed from the
internet, which may be a security risk. For example, attackers might misuse or
damage the product.
For more information on how to connect the switch unit to the LAN, and for the IP
address, see Chapter 4.3, "LAN connection", on page 151.

2.1.10 Connecting RF cables
Getting started
Preparing for use
2.1.9 Connecting monitor, mouse and keyboard
The HDMI and USB connectors for an external monitor, a mouse and a keyboard are
on the front panel of the R&S OSP, shown in Figure 2-16.
For connecting these devices, see Chapter 4.2, "Instrument control", on page 150.
Many modules are desigened for connecting test equipment via RF cables.
Excessive tightening of coaxial RF connections can damage the connectors of both
cables and modules. Too weak tightening leads to inaccurate measurement results.
Connecting RF cables / TORQUE RECOMMENDATIONS
For best connections, proceed as follows:
1. Carefully align the connectors along a common axis.
2. Mate the connectors along the common axis until the male pin of the inner connector engages with the female socket of the outer connector.
3. When fastening the connectors, only turn the nut of the outer connector until the
connectors are firmly coupled.
Avoid rotating the body of the outer connector.
4. If the inner connector is on a cable, hold it stationary with a spanner.
5. For fastening the connection, use a calibrated torque wrench suitable for the connector type.
Never use a standard open-end wrench.
6. Fasten the nut of the outer connector to the specified torque.
For specifications, refer to application note 1MA99, which is available on the
Internet at www.rohde-schwarz.com.
For N, SMA and PC connectors, we recommend applying the following torque:
● 150 N·cm for N connectors
● 56 N·cm for SMA connectors (standard, PTFE-filled)
● 90 N·cm for PC connectors (3.5 mm / 2.92 mm / 2.4 mm / 1.85 mm, air-filled)
Rohde & Schwarz offers torque wrenches for various connectors. For ordering
information, also refer to the application note 1MA99
7. Note that 3.5 & 2.92 mm PC connectors are incompatible with 2.4 & 1.85 mm PC
connectors.
2.1.11 Connecting control cables
Many modules are desigened for connecting test equipment via control cables. Typically, these connections are straight forward and require no precautions.

2.1.12 Switching on or off
Getting started
Preparing for use
However, take special care in the following cases:
●
In I/O modules (input / output), avoid overloading the digital input lines. The maximum voltage to be applied directly to the input connectors is TTL level: standard
3.3 V DC, tolerating up to 5 V DC. For voltages > 5 V DC up to 28 V DC, insert a
resistor in series with a minimum resistance of 22 kΩ.
●
In the satellite system, use the [Wired Link] connectors only for connecting the
remote control module R&S OSP-B200R with the satellite unit R&S OSP-B200S2.
Connecting a [Wired Link] connector to any other device's connector can damage
your equipment.
See Chapter 2.2.2.4, "Rear panel of the R&S OSP-B200S2 satellite unit",
on page 31, and Chapter 3.57, "R&S OSP-B200R remote control module",

Getting started
Preparing for use
To disconnect from power
1. Shut down the switch unit.
2. Disconnect it from the power source.
How to avoid losing settings
While the R&S OSP is in operating mode, if you switch it off using the rear panel switch
or by disconnecting the power cord, the instrument loses its current settings. (Operating mode is indicated by a green LED above the [Pwr] key.)
For example, if you have selected signal paths previously, you must select and enable
these paths again, when you restart the switch unit.
To avoid a loss of settings, press the [Pwr] key first to set the switch unit into standby
mode. Then shut it down properly by setting the rear AC power switch to position [O].
●
If "Configuration" > "General" > "Switch-On Reset" is activated, the R&S OSP
resets all internal latching switches during the startup procedure.
●
If "Configuration" > "General" > "Switch-On Action" is set to "Switch Path", the
R&S OSP loads the previously set path while booting. The switch unit activates this
path when the startup procedure is completed.
Display timeout
The OLED status display of a switch unit R&S OSP220 or R&S OSP320 serves for
showing you the network connection. The LAN connection is set typically at power-up.
The status display switches off automatically after setting the LAN connection with a
timeout specified by the Status Display Period. Without a network connection, the status display switches off with the same timeout after power-up. This feature helps to
prevent burn-in effects often seen in OLED displays.
When the switch unit is connected via a new network address, the status display is
switched on again for the next 30 minutes. (Your server can assign a new address, for
example, when you change the switch unit's network settings from static IP to DHCP.)
The RGB-LED touchscreen display in the R&S OSP230 and in the module
R&S OSP-B300M needs no burn-in protection. Thus, it has no timeout.
2.1.13 Checking the installed modules
The instrument is typically equipped with one or more optional switch modules.
You can visually check whether the modules listed on your delivery note correspond
with the installed modules. Each module's name is printed on its panel.
You can also view the installed modules in the "Module Operation" dialog (touchscreen
display or "WebGUI", see Chapter 2.3.2, "User interface and functional elements",
on page 34):

Figure 2-2: The module operation dialog, here with a single switch unit and 5 modules
The information in this dialog is updated during the booting process, when the
R&S OSP automatically scans all its installed modules. The switch unit stores the information on these modules in its internal flash memory (SD card).
If you have mounted additional modules or removed original ones, the switch unit
detects and stores this changed configuration of modules. If Module Check is enabled,
the R&S OSP automatically prompts you with information on the changed modules.
If the Virtual Mode is enabled, you can edit the list of frames (switch units) and their
modules.
To check the installed options from a remote computer in the same local area network
as the R&S OSP, you can use the remote control command ROUTe:MODule:
CATalog? on page 305.
2.1.14 Configuring the initial instrument settings
After startup, the switch unit is fully configured automatically, and ready for use.
However, you have many options to change the configuration, for example:
●
Edit the network settings, see Chapter 5.4.3, "Network", on page 217
●
Define or modify a setup of primary and secondary switch units, see Chapter 5.4.4,
"Interconnection", on page 220
●
Restore a previous setting, see "Backup/Restore" on page 223
