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

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 5. 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.

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, carrying and installing the product

The product is heavy and must be installed and set up by trained staff. Always use

appropriate lifting equipment when you lift or carry the product, like a forklift when the

R&S QAR50 is still packed in its original box or a crane when it is unpacked.

Safety instructions

Safety and regulatory information

R&S®QAR50

6User Manual 1179.4992.02 ─ 02

Lifting and carrying heavy items can cause structural or muscular injuries. Heavy items

can also cause other physical injuries like crushed body parts when they fall or tip over.

Because of its weight, at least two strong people are required to move or install the

R&S QAR50. During the installation, make sure that the installation site is only accessi-

ble to people working on the installation.

During transport, installation or repair, wear appropriate protective clothing that com-

plies with your local rules and regulations. If you are unsure of which equipment to use,

ask your safety inspector.

We recommend to wear:

●Safety shoes with toe cap and ESD protection.

●Protective gloves

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.

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.

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.

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.

●Only use the power cable delivered with the product. It complies with country-spe-

cific safety requirements. Only insert the plug into an outlet with protective conduc-

tor terminal.

●Only use intact cables and route them carefully so that they cannot be damaged.

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 deliv-

ered with the product or that is recommended in the product documentation or a

power supply that conforms to the country-specific regulations.

●Only connect the product to a power source with a fuse protection of maximum

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

Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind that the

casing is not waterproof. Do not use liquid cleaning agents.

Meaning of safety labels

Safety labels on the product warn against potential hazards.

Potential hazard

Read the product documentation to avoid personal injury or product damage.

Heavy product

Be careful when lifting, moving or carrying the product. Carrying the product requires a suffi-

cient number of persons or transport equipment.

Electrical hazard

Indicates live parts. Risk of electric shock, fire, personal injury or even death.

Hot surface

Do not touch. Risk of skin burns. Risk of fire.

Protective conductor terminal

Connect this terminal to a grounded external conductor or to protective ground. This connec-

tion protects you against electric shock if an electric problem occurs.

1.2 Labels on the product

Labels on the casing inform about:

●Personal safety, see "Meaning of safety labels" on page 7

●Product and environment safety, see Table 1-1

●Device information is provided on a sticker attached to the connector board.

For details, see Chapter 5.2.6, "Device ID", on page 29.

Table 1-1: Labels regarding product and environment safety

Labeling in line with EN 50419 for disposal of electrical and electronic equipment after the prod-

uct has come to the end of its service life.

3 Welcome

The R&S QAR50 is the ideal tool for accurately testing the quality of radomes and

bumpers in the automotive radar frequency range at the end-of-line (EOL). It features

sufficient space to easily accommodate bulky bumpers combined with spatially

resolved measurements to evaluate the homogeneity of design emblems. Its innova-

tive hardware concept enables impressively fast measurement times whereas the

modular software concept allows adaptation to your particular requirements.

Measurements:

●Precise reflection measurements from both sides for two frequency bands.

●Frequency-resolved reflection and transmission loss measurement.

●Transmission phase measurement.

●High-resolution reflection image.
