1 Safety and Regulatory Information
The product documentation helps you use the product safely and efficiently. Follow the
instructions provided here and in the Chapter 1.1, "Safety Instructions", on page 19.
Intended use
The product is intended for the development, production and verification of electronic
components and devices in industrial, administrative, and laboratory environments.
Use the product only for its designated purpose. Observe the operating conditions and
performance limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential dan-
gers and gives instructions on how to prevent personal injury or damage caused by
dangerous situations. Safety information is provided as follows:
●In Chapter 1.1, "Safety Instructions", on page 19. The same information is provi-
ded in many languages as printed "Safety Instructions". The printed "Safety
Instructions" are delivered with the product.
●Throughout the documentation, safety instructions are provided when you need to
take care during setup or operation.
1.1 Safety Instructions
Products from the Rohde & Schwarz group of companies are manufactured according
to the highest technical standards. To use the products safely, follow the instructions
provided here and in the product documentation. Keep the product documentation
nearby and offer it to other users.
Use the product only for its intended use and within its performance limits. Intended
use and limits are described in the product documentation such as the data sheet,
manuals and the printed safety instructions. If you are unsure about the appropriate
use, contact Rohde & Schwarz customer service.
Using the product requires specialists or specially trained personnel. These users also
need sound knowledge of at least one of the languages in which the user interfaces
and the product documentation are available.
If any part of the product is damaged or broken, stop using the product. Never open
the casing of the product. Only service personnel authorized by Rohde & Schwarz are
allowed to repair 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 person
can only carry a maximum of 18 kg safely depending on age, gender and physical con-
dition. Look up the maximum weight in the data sheet. Use the product 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 manufacturer.
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 electric shock,
serious personal injury or death if you touch the casing. If Rohde & Schwarz provides a
carrying bag designed for your product, 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 environments where
nonconductive contamination can occur. For more information on environmental condi-
tions 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 prod-
uct 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 sta-
bility. The feet can collapse if they are not folded out completely or if the product is
moved without lifting it. The foldable feet are designed to carry the weight of the prod-
uct, 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 prod-
ucts 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 and has to be connected to a fixed
installation used to supply energy-consuming equipment such as household applian-
ces and similar loads. Be aware 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 indicated
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.
●If a product has an exchangeable fuse, its type and characteristics are indicated
next to the fuse holder. Before changing the fuse, switch off the instrument and dis-
connect it from the power source. How to change the fuse is described in the prod-
uct documentation.
