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.

4.6 Considerations for test setups
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a
DUT.
19Getting Started 1178.7117.02 ─ 08
R&S®OSP
Considerations for test setups
► NOTICE! Electrostatic discharge can damage the electronic components of
the product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
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)
Preparing for use
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.
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.

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)

Preparing for use
Switching on or off
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.
4.11 Connecting control cables
Many modules are desigened for connecting test equipment via control cables.
Typically, these connections are straight forward and require no precautions.
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 OSPB200S2. Connecting a [Wired Link] connector to any other device's connector
can damage your equipment.
See Chapter 5.2.4, "Rear panel of the R&S OSP-B200S2 satellite unit",
on page 33.

To shut down the R&S OSP
1. NOTICE! Risk of data loss. See "How to avoid losing settings" on page 24.
Check the LED above the [Pwr] key on the front panel (labeled 7 in Fig-
ure 6-4).
Preparing for use
Switching on or off
● If the LED emits orange light
The switch unit is already in standby mode.
● Otherwise, if the LED emits green light , set the switch unit to standby
mode by pressing the [Pwr] key.
The LED changes from green to orange light, indicating standby mode.
The switch unit is now unavailable via LAN, even if connected.
2. Optionally, set the AC power switch on the rear panel to position [O].
The R&S OSP changes into off mode.
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.)
, do not press 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.

Checking the installed modules
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" parameter in the
"General" configuration tab (see user manual). 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, as described in the user manual.)
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.
Preparing for use
4.13 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 6.2, "User interface
and functional elements", on page 37):

To see the interaction dialog of any module, click its name in the list.

dialog
While the "Selection Mode" is active, tapping or clicking the icon of a relay, output
channel or other Switchable items does not change its state, but only selects or
deselects it. This selection is indicated by the icon's name and frame color
changing from gray to orange.
Use the selection mode for defining paths and output patterns. To select or
deselect all relays and output channels, go to "Module Operation" (or "Path
Switching") > "Context Menu" > "Path Selection" > "Select All" or "Deselect
All".
