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 Chapter 1.1, "Safety Instructions",

on page 5.

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 develop-

ment 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 performance limits stated in the data sheet.

Target audience

The target audience is developers and technicians. The required skills and expe-

rience in power and reflection measurements depend on the used operating con-

cept. 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

measurements 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

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.

1.1 Safety Instructions

ded 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.

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.
