1 Safety and regulatory information
The product documentation helps you use the product safely and efficiently. Fol-
low the instructions provided here and in the following chapters.
Intended use
Combined with the supported R&S power sensors, the R&S NRX base unit is
intended for power measurements in development and production. The supported
R&S power sensors are listed in the data sheet. Observe the operating conditions
and performance limits stated in the data sheet.
Target audience
The target audience is developers and technicians. The required skills and expe-
rience in power measurements depend on the used operating concept. While
manual operation is suitable for beginners, remote control requires expertise in
power measurements.
Depending on the used R&S power sensor, the applications vary greatly. A pro-
found knowledge of the intended application and test setup is recommended.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential
dangers 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 5. The same information is
provided 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.

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.
Cleaning the product
