also need sound knowledge of at least one of the languages in which the user
interfaces and the product documentation are available.
Never open the casing of the product. Only service personnel authorized by
Rohde & Schwarz are allowed to repair the product. If any part of the product is
damaged or broken, stop using the product. Contact Rohde & Schwarz customer
service at http://www.customersupport.rohde-schwarz.com.
Lifting and carrying the product
The product is heavy. Do not move or carry the product by yourself. A single per-
son can only carry a maximum of 18 kg safely depending on age, gender and
physical condition. Look up the maximum weight in the data sheet. Use the prod-
uct handles to move or carry the product. Do not lift by the accessories mounted
on the product. Accessories are not designed to carry the weight of the product.
To move the product safely, you can use lifting or transporting equipment such as
lift trucks and forklifts. Follow the instructions provided by the equipment manu-
facturer.
Choosing the operating site
Only use the product indoors. The product casing is not waterproof. Water that
enters can electrically connect the casing with live parts, which can lead to elec-
tric shock, serious personal injury or death if you touch the casing. If
Rohde & Schwarz provides accessories designed for your product, e.g. a carrying
bag, you can use the product outdoors.
Unless otherwise specified, you can operate the product up to an altitude of
2000 m above sea level. The product is suitable for pollution degree 2 environ-
ments where nonconductive contamination can occur. For more information on
environmental conditions such as ambient temperature and humidity, see the
data sheet.
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. Connect the product to a fixed
installation used to supply energy-consuming equipment such as household
appliances and similar loads. Keep in mind 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.
●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.

Electromagnetic compatibility classes
The electromagnetic compatibility (EMC) class indicates where you can operate
the product. The EMC class of the product is given in the data sheet under "Gen-
eral data".
●Class B equipment is suitable for use in:
– Residential environments
– Environments that are directly connected to a low-voltage supply network
that supplies residential buildings
●Class A equipment is intended for use in industrial environments. It can cause
radio disturbances in residential environments due to possible conducted and
radiated disturbances. It is therefore not suitable for class B environments.
If class A equipment causes radio disturbances, take appropriate measures to
eliminate them.
3.4 Setting Up the R&S FSWP
The R&S FSWP is designed for use on a bench top or in a rack.
See also:
●"Setting up the product" on page 10
●"Intended use" on page 9
3.4.1 Placing the Product on a Bench Top
To place the product on a bench top
1. Place the product on a stable, flat and level surface. Ensure that the surface
can support the weight of the product. For information on the weight, see the
data sheet.
2. WARNING! A stack of products can fall over and cause injury. Never stack
more than two products. Otherwise, mount them in a rack.
Stack as follows:
● All products must have the same dimensions (width and length).
● Do not exceed a total load of 50 kg placed on the product at the bottom of
the stack.

3. Grab the handles and push the R&S FSWP onto the shelf until the rack brack-
ets fit closely to the rack.
4. Tighten all screws in the rack brackets with a tightening torque of 1.2 Nm to
secure the R&S FSWP in the rack.
To unmount the R&S FSWP from a rack
1. Loosen the screws at the rack brackets.
2. Remove the R&S FSWP from the rack.
3. If placing the R&S FSWP on a bench top again, unmount the adapter kit from
the R&S FSWP. Follow the instructions provided with the adapter kit.
3.5 Connecting the AC Power
In the standard version, the R&S FSWP is equipped with an AC power supply
connector.
The R&S FSWP can be used with different AC power voltages and adapts itself
automatically to it. Refer to the datasheet for the requirements of voltage and fre-
quency.
For safety information, see "Connecting to power" on page 11.
To connect the AC power
1. Plug the AC power cable into the AC power connector on the rear panel of the
instrument. Only use the AC power cable delivered with the R&S FSWP.
2. Plug the AC power cable into a power outlet with ground contact.
The required ratings are listed next to the AC power connector and in the data
sheet.
For details on the connector, refer to Chapter 4.2.2, "AC Power Supply Connec-
tion and Main Power Switch", on page 46.
