1 Safety and regulatory information
The product documentation helps you use the product safely and efficiently. Follow the
instructions provided here and in the following chapters.
Intended use
Combined with a supported R&S NRT‑Zxx directional power sensor, the R&S NRT2
base unit is intended for power and reflection measurements in development and for
monitoring and maintenance purposes. The supported R&S NRT‑Zxx directional power
sensors are listed in the data sheet. Observe the operating conditions and perfor-
mance limits stated in the data sheet.
Target audience
The target audience is developers and technicians. The required skills and experience
in power and reflection measurements depend on the used operating concept. While
manual operation is suitable for beginners, remote control requires expertise in power
and reflection measurements.
Main applications are continuous monitoring of transmitter systems and power mea-
surements with digital modulation. A profound 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 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 9. 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

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.
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 dam-
aged or broken, stop using the product. Contact Rohde & Schwarz customer service at
http://www.customersupport.rohde-schwarz.com.
Lifting and carrying the product
The maximum weight of the product is provided in the data sheet. To move the product
safely, you can use lifting or transporting equipment such as lift trucks and forklifts. Fol-
low 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
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 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. Connect the product to a fixed
installation used to supply energy-consuming equipment such as household applian-
ces and similar loads. Keep in mind that electrically powered products have risks, such
as electric shock, fire, personal injury or even death.
