1 Preface
The R&S OSP-B157W8 or R&S OSP-B157W8PLUS and R&S OSP-B157WX are standard modules for the open switch platform R&S OSP.
The R&S OSP-B157WX serves as a frequency extension for the base module
R&S OSP-B157W8 or R&S OSP-B157W8PLUS. While the extension forwards lower
frequency signals to the base module, it can bypass higher frequency signals to an
appropriate measurement channel.
Both modules are typically used in the automatic test system R&S TS8997 that performs regulatory conformance tests of wireless short range devices (SRDs). The tests
cases are focused on the 2.4 GHz and 5 GHz frequency bands for Wi-Fi and ISM
applications (industrial, scientific and medical). These tests are performed according to
the standards FCC 15.407, ETSI EN 300 328, ETSI EN 301 893, ETSI EN 302 502,
ETSI EN 300 440 and others.
Intended use
The R&S OSP-B157W8, R&S OSP-B157W8PLUS and R&S OSP-B157WX are designated for the development, production and verification of electronic components and
devices in industrial and laboratory environments. Use the modules only for their designated purpose. Observe the operating conditions and performance limits stated in the
data sheets.
Preface
Designation "module" vs. "switch unit"
This manual uses the following nomenclature:
●
The R&S OSP-B157W8 is referred to as "base module".
●
The R&S OSP-B157W8PLUS is referred to as "base module".
●
The R&S OSP-B157WX is referred to as "extension module".
●
The R&S OSP is referred to as "switch unit".
Integration
●
The base module R&S OSP-B157W8 or R&S OSP-B157W8PLUS is (or must be)
integrated in an R&S OSP150 or R&S OSP120 switch unit.
●
The extension module R&S OSP-B157WX is (or must be) integrated in an
R&S OSP120 switch unit (not in an R&S OSP150).
Except for one optional additional single-slot module in slot A11 of the switch unit, no
additional modules can be installed in a single switch unit beside one R&S OSPB157W8, one R&S OSP-B157W8PLUS or one R&S OSP-B157WX. For all information
related to the R&S OSP switch units, refer to their operating manual.

Frequency ranges
Basically, the modules are designed to cover the 2.4 GHz and 5 GHz frequency bands.
However, some of the above mentioned regulatory ETSI and FCC tests include measuring spurious emissions up to 18 GHz or even up to 40 GHz.
Therefore, the frequency coverage of the modules is as follows:
●
The R&S OSP-B157W8 operates in a frequency range up to 6 GHz. The
R&S OSP-B157W8PLUS operates in a frequency range up to 7.5 GHz. Both base
modules offer a special by-path for spurious emissions measurements up to
18 GHz. The integrated power meter and signal conditioning is designed for inband use only.
The lower end of the frequency range of the R&S OSP-B157W8 and R&S OSPB157W8PLUS depends on the selected paths and application. It starts, for example, approximately at 100 MHz, if internal power measurements are involved, or
approximately at 1 GHz, if directional couplers are involved.
●
The R&S OSP-B157WX extends the spurious emissions frequency range up to
40 GHz. Signals to be measured in this frequency range are not forwarded to the
DUT input ports of the base module, but bypassed directly to the signal analyzer.
Preface
Key features of the base module R&S OSP-B157W8
The 6 GHz module R&S OSP-B157W8 with up to 8 channels is based on a printed RF
switch board in solid-state relay (SSR) architecture. It allows flexible operation of the
connected DUT (up to 8 ports) and measurement instruments.
The module features:
●
Signal conditioning by integrated attenuators, couplers and combiners (without
amplifiers or filters)
●
RF switching for wireless test cases up to 6 GHz
●
RF switching for spurious emission measurements up to 18 GHz (exception: if a
frequency extension module R&S OSP-B157WX is present, these signals are handled within the extension module)
●
Power measurements in the 2.4 GHz and 5 GHz bands with specific evaluations
for wireless standards
●
Built-in data acquisition board for control of the signal paths and for collection and
A/D conversion of the power measurements
●
Multiple trigger input and output options
●
External clock input
●
Video input
●
LAN interface for remote control of the module operation by the test software

Each of the 8 configurable channels in the R&S OSP-B157W8 and R&S OSPB157W8PLUS has the following integrated semiconductor components:
●
An individually programmable attenuator
●
An analog power detector for synchronous RMS power measurement with high
sampling rate and burst detection
●
An A/D converter for the power measurement results
●
Solid-state switches, which enable:
– Switching the (vector) signal generator output to the calibration port or to the
DUT ports
– Switching the measurement paths from DUT ports to a spectrum analyzer / test
receiver or to the power measurement
– Signal conditioning via the integrated couplers, directional couplers, attenuators
and combiners
Key features of the frequency extension module R&S OSP-B157WX
Preface
The 40 GHz module R&S OSP-B157WX is especially designed to provide RF switching for spurious measurements up to 40 GHz.
It uses coaxial RF architecture and features:
●
Electromechanical RF relay switches for flexible operation of up to 8 DUT channels
●
The module can forward incoming signals on each DUT channel to the connected
DUT input of the R&S OSP-B157W8 or R&S OSP-B157W8PLUS. This forwarding
is used for measurements at frequencies up to 6 GHz, which the R&S OSPB157W8 can handle, or up to 7.5 GHz, which the R&S OSP-B157W8PLUS can
handle.
●
Alternatively, incoming signals on one single DUT channel can be switched to the
module's [Rx] port and on to a connected signal analyzer, receiver or other measurement instrument. This switching state is typically used for measurements at
frequencies above 6 GHz or 7.5 GHz and up to 40 GHz, which the base modules
cannot handle. (Signals for spurious emission measurements up to 18 GHz are
also switched to the instrument connected to the extension module's [Rx] port.)
●
If the R&S OSP-B157WX forwards the DUT's signals, it also switches the signal
analyzer path from its [RxOUT] port (input port) to its [Rx] port. This [Rx] port is
connected to the signal analyzer or test receiver, while the [Rx] port of the
R&S OSP-B157W8 or R&S OSP-B157W8PLUS is connected to the [RxOUT] port
(input port) of the R&S OSP-B157WX.
●
Additionally, you can add the signal of a companion device to one of the DUT paths
via its internal switches and a directional coupler. The type of companion device
depends on the DUT. For example, if your DUT is a Wi-Fi transceiver, the companion device can be a wideband radiocommunication tester R&S CMW500. In this
example, it would simulate a wireless router that maintains a bidirectional connection with the transceiver.

If your delivery includes a module that is not mounted in a switch unit, be especially
careful with unpacking the module, which is not protected in a casing.
Check the delivery for completeness according to the included shipment list. If the
delivery is incomplete, contact Rohde & Schwarz.
Retain the original packing material. If the instrument needs to be transported or shipped later, you can use the material to protect the control elements and connectors.
Preparing for Use
Mounting the Base Module
Mounting modules into switch units
●
If you have received one or more modules that are already integrated in switch
units, you can skip the chapters Mounting the Base Module and Mounting the
Extension Module. Proceed with Chapter 3.5, "Putting into Operation",
on page 22.
●
If you have received one or more modules that are not yet integrated in switch
units, proceed with chapters Mounting the Base Module and Mounting the Exten-
sion Module.
3.2 Mounting the Base Module
Mounting the base module R&S OSP-B157W8 or R&S OSP-B157W8PLUS into an
R&S OSP150 or R&S OSP120 switch unit requires the space of two slots: rear slots
A12 and A13 together with front slots A12F and A13F. Typically, the rear slot A11
remains free, but optionally it can remain occupied by a single-slot module (not operational). Only one base module fits into one R&S OSP150 or R&S OSP120 switch unit.

R&S®OSP‑B157W8 R&S®OSP‑B157W8PLUS R&S®OSP‑B157WX
Risk of electric shock
Opening a switch unit implies the risk of touching current-carrying components and suffering an electric shock, if the device is not properly disconnected from grid power.
Before opening the casing, ensure that the switch unit is disconnected from the power
supply by removing the plug from the rear AC power connector.
Observe the safety instructions for units with a removable casing.
Carefully follow the step-by-step instructions for module replacement to avoid injury
and to help ensure safe operation.
Risk of injuries
When removing the rear feet, the switch unit can slip out of its casing.
To avoid the risk of personal injuries and any damage, put the switch unit onto its front
handles before removing the rear feet and taking off the casing.
Preparing for Use
Mounting the Base Module
When mounting the casing back onto the switch unit, take care not to pinch your fingers. Also pay attention not to damage or pull off protruding parts, especially cables.
Screw the rear feet back on immediately after mounting the casing. Do not move the
switch unit with the rear feet missing.
Removing an existing (old) R&S OSP-B157 module
If you want to install the R&S OSP-B157W8 or R&S OSP-B157W8PLUS in a switch
unit, which is occupied by an existing module (for example R&S OSP-B157), first
remove the existing module.
Remove the existing module in the reverse order of the mounting procedure, described
in the service manual of the R&S OSP (1505.3896.82), for example chapter "Replacing
the Option OSP-B157".
Mounting procedure for the R&S OSP-B157W8 or R&S OSP-B157W8PLUS
For mounting the module into an R&S OSP150 or R&S OSP120 switch unit:

3.3 Mounting the Extension Module
Mounting the frequency extrension module R&S OSP-B157WX into an R&S OSP120
switch unit requires the space of two slots: rear slots A12 and A13 together with front
slots A12F and A13F. Typically, the rear slot A11 remains free, but optionally it can
remain occupied by a single-slot module (not operational). Only one R&S OSPB157WX module fits into one R&S OSP120 switch unit.
Risk of electric shock
Opening a switch unit implies the risk of touching current-carrying components and suffering an electric shock, if the device is not properly disconnected from grid power.
Before opening the casing, ensure that the switch unit is disconnected from the power
supply by removing the plug from the rear AC power connector.
Observe the safety instructions for units with a removable casing.
Carefully follow the step-by-step instructions for module replacement to avoid injury
and to help ensure safe operation.

Risk of injury when stacking instruments
A stack of instruments can tilt over and cause injury if not stacked correctly. Furthermore, the instruments at the bottom of the stack can be damaged due to the load
imposed by the instruments on top.
Observe the following instructions when stacking instruments:
●
Never stack more than three instruments. If you need to stack more than three
instruments, install them in a rack.
●
The overall load imposed on the lowest instrument must not exceed 500 N.
●
It is best if all instruments have the same dimensions (width and length).
If you need to stack smaller instruments on the top, the overall load imposed on the
lowest instrument must not exceed 250 N.
●
If the instruments have foldable feet, fold them in completely.
Preparing for Use
Putting into Operation
Risk of injury if feet are folded out

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.
For putting the modules into operation after they are mounted inside a switch unit and
optionally inside a rack, proceed as described in the operating manual of the
R&S OSP. This manual also contains valuable information on the switch unit's setup,
on remote operation, on working with the operating system, and much more.
Unlike all other modules for R&S OSP switch units, the R&S OSP-B157W8 and
R&S OSP-B157W8PLUS are not equipped with on-board memory to store the switching configuration of the module's signal paths. Therefore, the hosting switch unit cannot
recognize the module. Instead, the module's LAN interface must be connected to the
control computer and the switching configuration must be saved as a "Hardware
Setup" in the R&S WMS32 software. In this software, the switching configuration of the
R&S OSP-B157W8 and R&S OSP-B157W8PLUS is already implemented.

Use RF connector adapters as port savers
SMA and K-type RF connectors have a limited lifetime. It is typically limited to 500 connector mating cycles, due to normal wear. After this number of mating cycles, the connectors must be replaced.
●
The SMA connectors on the 8 DUT ports at the front panel of the R&S OSPB157W8 and R&S OSP-B157W8PLUS are soldered in. Therefore, their replacement is a costly and time-consuming procedure, which must be handled by
Rohde & Schwarz service.
To save the lifetime of these RF connectors, use the 2.92 mm K-type RF connector
adapters as port savers on the original connectors. A set of 8 adapters is included
in the delivery. Fix the adapters with a torque of 0.8 Nm to 1.1 Nm.
Leave the port saver adapters on the ports and connect your DUT channels to
these adapters, until the lifetime of the adapters is reached, due to wear. Then
replace the worn port saver adapters for new ones.
Preparing for Use
Putting into Operation

●
If any SMA or K-type connectors of the R&S OSP-B157WX are worn, replacing
these connectors is much more simple, because they are not soldered in.
Refer to the switch unit's operating manual for more operation information regarding,
for example, power supply, connection, grounding, ambient conditions, ventilation, system integration, switching on or reaching the currentless state.

Connecting Devices to the Base Module
The exact behavior of the module is test-case-specific and depends on the applicable
test standard. This flexibility allows setting up and handling complex test and measurement sequences with the connected devices.
4.1 Connecting Devices to the Base Module
The base module has various external connectors on its front and rear panel: SMA for
RF signals, BNC for analog and digital trigger control, D-Sub 9 for digital trigger control
and LAN for Ethernet access. The details of these connections are described in
Table 4-1.
Observe maximum input power and no DC voltage
All front connectors and some rear connectors have the following limitations:
●
A maximum tolerable input power level (dBm)
●
No tolerance for a direct current (DC) voltage share in the input signal
Tour of the Base Module
If the input signals exceed these limits, the internal circuits of the module can be damaged.
Do not exceed the dBm levels and "0 VDC" limits that are indicated on the front and
rear panels.
Depending on the switch unit that you use, the following additional connectors are
available:
●
If you use an R&S OSP150 switch unit, its rear panel has a power supply connector with fuse.
●
If you use an R&S OSP120 switch unit, its front panel has a DVI video monitor
interface and two USB 2.0 ports (all inactive in this setup). Its rear panel has a
power supply connector with fuse.
For information on the various connectors of the switch unit and for replacing the fuse,
refer to the operating manual of the R&S OSP.
Connect the power supply connector to an isolated ground receptacle of your mains
grid. The supply voltage must be between 110 VAC and 240 VAC with frequencies
ranging from 50 Hz to 60 Hz. Within these ranges, the device is automatically adapted
to the supply voltage. To turn the power on or off, put the AC power switch into position
I (on) or 0 (off).
The following table describes all other external connectors of the base module.

5 Tour of the Extension Module
The frequency extension module R&S OSP-B157WX must be mounted in an
R&S OSP120 switch unit.
This switch unit has front connectors for a USB keyboard, USB mouse and DVI display
for manual operation. However, we recommend connecting the switch unit via Ethernet
(LAN) to your control computer for remote operation by the software R&S OSP Panel.
Operation is described in Chapter 6, "Operating the Modules", on page 34 and in the
operating manual of the R&S OSP switch units.
On the front panel, the R&S OSP-B157WX has the connectors for up to eight DUT
channels with corresponding forwarding (loop-through) output ports and the connectors
for the test instruments:
Tour of the Extension Module
Figure 5-1: R&S OSP-B157WX mounted in R&S OSP120 (front panel view)
The module has no rear connectors, but just blind plates. The only connectors on the
rear panel are the switch unit's power supply, LAN interface and CAN bus port.
Figure 5-2: R&S
Use the switch unit's LAN connector for remote control
In contrast with the base module, the frequency extension module has no LAN connector of its own.
For controlling the R&S OSP-B157WX, use the RJ45 LAN connector on the rear panel
of the switch unit.
Hence, for controlling a combination of both the R&S OSP-B157W8 or R&S OSPB157W8PLUS and R&S OSP-B157WX in an R&S TS8997 test system, use two LAN
cables to connect the modules to the test systems' Ethernet switch.

Tour of the Extension Module
With this RF circuitry, the R&S OSP-B157WX is operated in the test system as follows:
●
Incoming signals on each DUT channel are forwarded to the connected DUT input
of the base module R&S OSP-B157W8 (supporting up to 6 GHz) respectively
R&S OSP-B157W8PLUS (supporting up to 7.5 GHz).
●
Incoming signals on one single DUT channel at frequencies above 6 GHz respectively above 7.5 GHz are switched to the module's [Rx] port.
Optionally, the control system can switch an [RxOUT] signal (instead of a DUT) or a
[X1] signal (companion device, in addition to a DUT) to the module's [Rx] port.
Signal paths for different frequency ranges
You must define the signal paths in such a way that the test system performs out-ofband measurements up to 40 GHz via the R&S OSP-B157WX.
5.1 Connecting Devices and a Base Module to the Extension Module
We recommend placing the R&S OSP-B157WX on top of the base module or mounting the two modules in the same arrangement into a 19'' rack.

Connecting Devices and a Base Module to the Extension Module
7. Connect the port [Rx] of the R&S OSP-B157WX to the input port of your measure-
ment instrument, for example a spectrum analyzer or test receiver.
8. On the rear panel of the R&S OSP-B157WX, connect the switch unit's RJ45 [LAN]
port for remotely controlling the R&S OSP-B157WX as described in the operating
manual of the R&S OSP switch units. Note that this usage is different from the
base module, where you must use the module's LAN port instead of the switch
unit's LAN port. Do not use the CAN port for controlling the R&S OSP-B157WX.
9. Connect the power supply connector to an isolated ground receptacle of your
mains grid. The supply voltage must be between 110 VAC and 240 VAC with frequencies ranging from 50 Hz to 60 Hz. Within these ranges, the device is automatically adapted to the supply voltage. To turn the power on or off, put the AC power
switch into position I (on) or 0 (off).

R&S®OSP‑B157W8 R&S®OSP‑B157W8PLUS R&S®OSP‑B157WX
Configuring Devices and Signal Paths
If, instead of factory mounting, the modules are mounted by the Rohde & Schwarz service, the calibration is preserved.
For a later recalibration, including the power detectors in the R&S OSP-B157W8 or
R&S OSP-B157W8PLUS, we recommend that you send your switch unit (with the
module) to the Rohde & Schwarz service.
Alternatively, for your own module calibration, you must switch each path individually
and determine the path attenuation with your generator and measuring instrument.
However, this calibration does not include the power detectors in the R&S OSPB157W8 or R&S OSP-B157W8PLUS.
6.2 Configuring Devices and Signal Paths
The base module R&S OSP-B157W8 or R&S OSP-B157W8PLUS and the frequency
extension module R&S OSP-B157WX are designed only for use in the R&S TS8997
regulatory conformance test system.
Operating the Modules
To configure the modules for this system, the R&S EMC32 software in the R&S RF
Test Suite offers a "WMS Configuration" wizard.
Access: "Extras" > "Wizards" > "WMS Configuration"
To use the wizard:
●
Insert the USB flash drive, which is included in the delivery, into a free USB port of
your computer.

Configuring Devices and Signal Paths
●
Have the address for each of your devices available. (The type of address depends
on the device's interface and its protocol, which can be IP, GPIB or USB / RS232.)
Obtaining valid IP addresses
If your network does not support DHCP or if you choose to disable dynamic TCP/IP
configuration, you must assign valid address information before connecting the instrument to the LAN. To obtain a valid IP address, contact your network administrator, as
connection errors can affect the entire network.
If required, see Chapter 10.2, "Resolving Network Connection Failures", on page 71.
In the wizard dialog, proceed as follows:
1. In the list of devices, enter an arbitrary ("speaking") name and the address for each
of your devices.
For example, if your spectrum analyzer has the IP address 10.113.0.104, enter
it as TCPIP::10.113.0.104::inst0::instr
2. For each device that is not present in your setup, select "<none>".
Operating the Modules
3. Check the checkbox "Import OSP-B157WX attenuation files".
4. Click "select source Folder".
5. Select the folder on the USB flash drive that contains the calibration data of your
R&S OSP-B157WX.
6. Confirm your selection to import the files.
7. In the field "Hardware Setup", enter a name for your hardware setup.
8. Check the checkboxes "Replace existing DeviceList entries" and "Replace existing
attenuation tables".
Note: We do not recommend using the same computer for a different test system,
too. If you let the wizard replace existing device entries and tables, these changes
can corrupt existing test templates required for another test system.
If you still wish to use the same computer for several test applications, proceed as
described in Chapter 6.2.1, "Creating Separate Profiles for Multiple Applications",
on page 37.
9. Click "Create".
The wizard creates the device entries in the device list, the required signal paths
and attenuation tables and a hardware setup.
10. When the wizard procedure is completed, restart your computer.
The path configuration is now stored and available for remote control operation.
The final preparatory steps are creating a DUT configuration and a test template as
described in the documentation (help function) of the R&S RF Test Suite software, sec-
tion "WMS Measurements (WMS32)".

Note that the R&S OSP-B157WX is listed twice in the R&S OSP Panel dialog, as the
module occupies two slots in the switch unit and uses two internal interfaces.
Also note that the base modules R&S OSP-B157W8 and R&S OSP-B157W8PLUS are
not recognized by the R&S OSP Panel software.
6.2.1 Creating Separate Profiles for Multiple Applications
If you want to run more than one test application on the same computer, we recommend creating an additional profile for each application.
To do so, proceed as follows:
1. Go to the R&S EMC32 program icon in the Windows start menu.
2. Drag this program icon to your desktop while pressing the [Alt] key.
This creates a program link with a new icon on the desktop.
3. Right-click the new program link icon.

8 Remote Control Commands
This chapter describes the remote control commands for direct communication with the
modules R&S OSP-B157W8 or R&S OSP-B157W8PLUS and R&S OSP-B157WX via
LAN interface and SCPI commands.
SCPI commands
Operation of the R&S OSP does not require that you send any SCPI commands. This
function is an additional feature for test and debug purposes. Using SCPI commands
requires knowledge of the R&S OSP remote control commands. For details, refer to
the operating manual of the R&S OSP.
For normal operation of the modules, use the graphical user interface of the
R&S WMS32 software.
Service-related RC commands are only available to Rohde & Schwarz personnel.
These commands are described in the service manual (1178.6504.02) of the
R&S OSP-B157W8, R&S OSP-B157W8PLUS and R&S OSP-B157WX.
Remote Control Commands
For direct SCPI communication with the modules, proceed as follows:
●
If you want to communicate with the module R&S OSP-B157W8 or R&S OSP-
B157W8PLUS:
1. Connect the module's LAN connector (Figure 4-2) to your control computer or to

[W | DBM] Specifies the unit for the threshold level: "W" = watts, "DBM" =
dB.
We recommend using "DBM", which sets the threshold level in
relation (dB) to the highest value in the sum-power measurement.
Range: -200 to 200
*RST: 30
Default unit: dB
SUMPowerdetector:DCYCle?
Returns the duty cycle, calculated over all bursts within the sum-power measurement.
Note: Since the DUTs are "load based", hence the individual durations of the bursts
depend on the actual data transfer, calculating the duty cycle requires a statistical evaluation of a number of bursts that is sufficient to do statistics.

Replacing the Power Supply Fuses
9 Maintenance
The instrument does not need periodic maintenance. Only cleaning the instrument is
recommended.
When ordering spare parts, follow the instructions in the Service Manual and the safety
instructions. Find order numbers for spare parts in the service manual, which also
includes further information on troubleshooting and repair.
Mounting the modules into a switch unit is described in Chapter 3, "Preparing for Use",
on page 12.
Due to normal wear, the SMA and K-type RF connectors of the modules have a limited
lifetime of typically 500 connector mating cycles. If these connectors are worn, replace
them.
For the hard-to-replace DUT ports of the base module R&S OSP-B157W8 or
R&S OSP-B157W8PLUS, we recommend that you Use RF connector adapters as port
savers. Once the port savers are worn, replace them with new connector adapters.
Maintenance
9.1 Replacing the Power Supply Fuses
The R&S OSP is protected by two fuses, located in the fuse holder below the power
switch on the rear panel.
Use only fuses of the type IEC 60127-2 T4.0A/250V (order no. 0020.7600.00) for all
nominal AC supply voltages specified in the data sheet.
Risk of electric shock
The fuse is part of the main power supply. Therefore, handling the fuse while power is
on can lead to electric shock. Before opening the fuse holder, make sure that the
instrument is switched off and disconnected from all power supplies.
Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same
type and rating.
To replace the fuses
1. Switch off the instrument.
2. Disconnect the power cable.
3. Open the lid of the AC power connector, using, for example, a small screwdriver.
4. Lift the fuse holder out of its slot.
5. Remove both fuses.

Page 69
R&S®OSP‑B157W8 R&S®OSP‑B157W8PLUS R&S®OSP‑B157WX
6. Insert the new fuses.
7. Push the fuse holder back into its slot.
8. Close the lid.
9. Reconnect the power cable.
9.2 Cleaning
Risk of electric shock
If moisture enters the casing, for example if you clean the instrument using a moist
cloth, contact with the instrument can lead to electric shock. Before cleaning the instrument other than with a dry cloth, make sure that the instrument is switched off and disconnected from all power supplies.
Maintenance
Cleaning
Instrument damage caused by cleaning agents
Cleaning agents contain substances such as solvents (thinners, acetone, etc.), acids,
bases, or other substances. Solvents can damage the front panel labeling, plastic
parts, or screens, for example.
Never use cleaning agents to clean the outside of the instrument. Use a soft, dry, lintfree dust cloth instead.
Risk of instrument damage due to obstructed fans
If the instrument is operated in dusty areas, the fans become obstructed by dust or
other particles over time. Check and clean the fans regularly to ensure that they always
operate properly. If the instrument is run with obstructed fans for a longer period, the
instrument overheats, which can disturb the operation and even cause damage.
1. Clean the outside of the instrument using a soft, dry, lint-free dust cloth.
2. Check and clean the fans regularly to ensure that they always operate properly.
3. Clean the touchscreen as follows:
a) Apply a small amount of standard screen cleaner to a soft cloth.
b) Wipe the screen gently with the moist, but not wet, cloth.
c) If necessary, remove any excess moisture with a dry, soft cloth.

9.3 Storing and Packing
The storage temperature range of the instrument is given in the data sheet. If the
instrument is to be stored for a longer period of time, it must be protected against dust.
Repack the instrument as it was originally packed when transporting or shipping. The
two protective foam plastic parts prevent the control elements and connectors from
being damaged. The antistatic packing foil avoids any undesired electrostatic charging
to occur.
If you do not use the original packaging, use a sturdy cardboard box of suitable size
and provide for sufficient padding to prevent the instrument from slipping inside the
package. Wrap antistatic packing foil around the instrument to protect it from electrostatic charging.

Flashing green: busy (measurement or update)
●
Red: error, proceed as follows:
– First try a restart.
– If the LED is still red, install a firmware update.
– If the LED is still red, contact Rohde & Schwarz service.
Troubleshooting
The "Ready" LED can show the following states:
●
Yellow: trigger is set
●
Green: trigger is released
10.2 Resolving Network Connection Failures
Risk of network connection failure
Network cables and cable connectors of poor quality, or failures in the autonegotiation
process, can cause network connection failures.
If the network connection to the instrument fails, check the network infrastructure and
contact your network administrator.
Several issues may cause failures in the network connection to the instrument. This
section lists the most likely reasons and the recommended solutions.
Common reasons for network connection failures
●
Network connecting cables and cable connectors of poor quality
●
Incompatibility between the network interface of the base module and certain
switches or routers available on the market
●
An invalid IP address assigned to the instrument

Consult your network administrator before performing the following tasks:
●
Connecting the instrument to the network
●
Configuring the network
●
Changing IP addresses
●
Exchanging hardware
Errors can affect the entire network.
Possible solutions
●
Check the network infrastructure. Exchange connecting cables if obvious damage
is visible.
●
Observe the link status LED on the connected network device. The link status LED
is located next to the LAN connector. If a link failure is detected, connect the instrument to a different device port or to a different network device.
●
Check whether the LAN interface and the required LAN services are enabled.
