Safety and regulatory information
Safety instructions
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 accessible to people working on the installation.
During transport, installation or repair, wear appropriate protective clothing that complies 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 product 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 conditions 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 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 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-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 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 delivered with the product or that is recommended in the product documentation or a
power supply that conforms to the country-specific regulations.

Setting up the R&S QAR50
You can set up the R&S QAR50 in two different ways: lying on its long side ("lying position") or standing upright on one of its short sides ("upright position"). By default, the
R&S QAR50 is designed to stand on a pair of feet that are part of the delivery.
For the upright position, make sure that the side with the connector board is at the bottom.
The R&S QAR50 must be placed on a level surface. This is important not only for
safety reasons, but also to get valid measurement results. If the body of the
R&S QAR50 is not at a right angle to the floor, measurement results can be invalid.

Instead of using the supporting feet, you can also integrate the R&S QAR50 in a production line system. For these special setups, contact your Rohde & Schwarz representative.
Attaching the supporting feet
The R&S QAR50 is delivered with a pair of feet that you can attach to the R&S QAR50.
All required parts (feet, screws and washers) are part of the delivery.
The supporting feet are bent at their ends to make the R&S QAR50 more stable. Make
sure to align the feet correctly with the bent parts facing away from the ends of the
main body.
Figure 4-4: Correct alignment of the supporting feet
After you have unpacked the R&S QAR50, it usually rests in lying position on the floor.
The way to attach the feet depends on the way you set up the R&S QAR50 (lying position or upright position).
WARNING! Risk of physical injury caused by heavy items.. See "Lifting, carrying
1.
and installing the product" on page 5.
Attaching the feet requires you to tilt the R&S QAR50 by 90° at least once.

Preparing for use
Installing the R&S
QAR50
To tilt the R&S QAR50, you can attach a suitable aid like a handle to the mounting
holes not needed for the feet. While tilting the R&S QAR50, be careful not to damage the R&S QAR50 or the supporting feet. One person must secure the
R&S QAR50 while another person tilts the R&S QAR50.
For the lying position, proceed as follows to attach the supporting feet.
a) Tilt the R&S QAR50 by 90° to an upright position (make sure that the side with
the connector board is on the bottom).
Figure 4-5: Tilting the R&S QAR50 into an upright position
b) Screw the two feet to the mounting holes indicated in Figure 4-6 with an Allen
wrench. The screws and wrench are part of the delivery (M8X45).
Put the washers between screw heads and feet.

QAR50
Moving the R&S QAR50
Use a crane or similar device to move the R&S QAR50 from one location to another.
The process is similar to lifting the R&S QAR50 out of the transport box ("Lifting the
R&S QAR50 out of the transport box" on page 12).
During the whole process, the feet can remain attached to the R&S QAR50.
WARNING! Risk of physical injury caused by heavy items. See "Lifting, carrying
1.
and installing the product" on page 5.
The product is heavy. Moving the R&S QAR50 safely is only possible with appropriate lifting equipment (like a crane) and a suitable lifting harness (like a four leg
rope). Commission personnel that is qualified to safely attach the R&S QAR50 to
the lifting equipment and to operate the lifting equipment.
Unscrew the caps of the mounting holes you need (M8X16 screws).
Depending on the setup (lying or upright position), use the mounting holes indicated in Figure 4-11 to lift the R&S QAR50. Do not use different mounting holes and
always use four mounting holes to distribute the weight equally.
● For the lying position: Use the mounting holes on top of the R&S QAR50. Use
either the four outer mounting holes (variant 1 in Figure 4-11) or the inner
mounting holes (variant 2 in Figure 4-11).
● For the upright position: Use the mounting holes on the opposite side of the
connector board. The side with the connector board must always be on the bottom.

port box" on page 12.
4. Carefully move the R&S QAR50 to its new location.
5. Remove the lifting equipment from the R&S QAR50.
6. Remove the eye bolts from the mounting holes.
7. Screw the caps of the mounting holes back in (M8X16 screws).
4.4 Considerations for test setup
Integration of the R&S QAR50 at the workplace
The R&S QAR50 has several edges that are required by its functionality. To avoid
physical injuries like head lacerations, take care of an appropriate ergonomic integration of the device at the workplace, especially if frequent human interaction with the
device is expected.
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
19User Manual 1179.4992.02 ─ 02
R&S®QAR50
Preparing for use
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF and LAN
cables.
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.

Connecting the R&S
QAR50
1. Connect a monitor to the DisplayPort port on the R&S QAR50.
As a power source, you can use a household AC outlet to supply the monitor with
power (for monitors with a light-current extension cable).
Note: We recommend using a monitor with a resolution of at least 1920 x 1080.
Lower resolutions can lead to an incorrect display of the measurement data.
2. Connect a keyboard and a mouse to two of the USB ports.
3. Optional: Establish a connection to your LAN via the LAN interface.
Note: Always connect all devices before connecting the R&S QAR50 to the mains
supply.
Connecting to power
The R&S QAR50 contains an AC power supply on the connector board.
For safety information, see "Connecting to power" on page 6.
1. Plug the AC power cable into the AC power connector on the connector board.
Only use the AC power cable delivered with the product.
2. Plug the AC power cable into a power outlet with ground contact.
The required ratings are listed next to the AC power connector and in the data
sheet.
