3.1.1 Unpacking and Checking
Check the equipment for completeness using the delivery note and the accessory lists
for the various items. Check the R&S NRX for any damage. If there is damage, imme-
diately contact the carrier who delivered the R&S NRX. Make sure not to discard the
box and packing material.
Packing material
Retain the original packing material. If the instrument needs to be transported or ship-
ped later, you can use the material to protect the control elements and connectors.
3.1.1.1 Accessory List
The R&S NRX comes with the following accessories:
●Printed getting started manual
●Multilingual safety brochure
●Additive data sheet ref. China ROHS
●Country-specific power cable
3.1.2 Operating Conditions
Specific operating conditions are required to ensure accurate measurements and to
avoid damage to the R&S NRX and connected devices. Before switching on the R&S
NRX, observe the information on appropriate operating conditions provided in the basic
safety instructions and the data sheet of the R&S NRX.
In particular, ensure the following:
●The R&S NRX is dry and shows no sign of condensation.
●The ambient temperature does not exceed the range specified in the data sheet.

●Signal levels at the input connectors are all within the specified ranges.
●Signal outputs are connected correctly and are not overloaded.
3.1.3 Considerations for Test Setup
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT
or test fixture to the instrument's test ports.
►NOTICE! Risk of electrostatic discharge (ESD). Electrostatic discharge (ESD) can
damage the electronic components of the R&S NRX and the device under test
(DUT).
Ground yourself to avoid electrostatic discharge (ESD) damage:
● Use a wrist strap and cord to connect yourself to the ground.
● Use a conductive floor mat and heel strap combination.
EMI impact on measurement results
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated electromagnetic interference (EMI):
●Use suitable shielded cables of high quality. For example, use double-shielded RF
and LAN cables.
●Always terminate open cable ends.
●Note the EMC classification in the data sheet.
●Do not use USB connecting cables exceeding 5 m.
3.1.4 Placing on a Bench Top
Place the R&S NRX on a stable and level surface. The R&S NRX can be used in hori-
zontal position, standing on its feet, or with the support feet on the bottom extended.
Do not place anything on top of the R&S NRX, if the R&S NRX is not in a level posi-
tion.
To place the R&S NRX on a bench top
1. Place the R&S NRX on a stable, flat and level surface. Ensure that the surface can
support the weight of the R&S NRX. For information on the weight, see the data
sheet.
2. CAUTION! Foldable feet can collapse. 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
product is moved without lifting it. The foldable feet are designed to carry the
weight of the product, but not an extra load.
With folded-out feet, do not place anything on top or underneath the instrument.

3. WARNING! A stack of products can fall over and cause injury. Never stack more
than three products on top of each other. Instead, mount them in a rack.
Stack as follows:
● It is best if all instruments have the same dimensions (width and length).
● The overall load on the lowest instrument must not exceed 500 N.
● With smaller instruments on top of the lowest instrument, the overall load on
the lowest instrument must not exceed 250 N.
Too many instruments
max. 500 N
Correct Different dimensions
max. 250 N
4. NOTICE! Overheating can damage the product.
Prevent overheating as follows:
●Keep a minimum distance of 10 cm between the fan openings of the R&S NRX
and any object in the vicinity.
● Do not place the R&S NRX next to heat-generating equipment such as radia-
tors or other instruments.
3.1.5 Mounting in a Rack
1. Order one of the rack adapter kits designed for the R&S NRX. For the order num-
ber, see data sheet.
2. Follow the installation instructions provided with the adapter kit.
3. NOTICE! Insufficient airflow can cause overheating and damage the product.
Design and implement an efficient ventilation concept for the rack.
3.1.6 Connecting to the AC Power Supply
The R&S NRX can be used with different AC power voltages and adapts itself auto-
matically to them. Adjusting the R&S NRX to a particular AC supply voltage is therefore
not required. Refer to the data sheet for the requirements of voltage and frequency.
The power switch can be set to two positions:
●[0]: The instrument is disconnected from the mains.

●[I]: The instrument is power-supplied. It is either ready for operation (STANDBY) or
in operating mode.
1. Plug the AC power cable into the AC power connector on the rear panel of the
R&S NRX. Only use the power cable delivered with the R&S NRX.
2. Plug the AC power cable into a power outlet with ground contact. The R&S NRX
complies with safety class EN61010-1.
The required ratings are listed next to the AC connector and in the data sheet.
Further information:
●Chapter 3.2.2.5, "AC Supply and Power Switch", on page 29
3.1.7 Switching On or Off
The possible instrument states are described in Chapter 3.2.1.6, "On/Standby Key",
on page 27.
To switch on the R&S NRX
1. To turn on the power, press the AC power switch at the rear to position [I] (On).
After power-up, the R&S NRX is in standby or ready state, depending on the posi-
tion of the on/standby key.
2. If the R&S NRX is in standby state, press the on/standby key.
The R&S NRX initiates its startup procedure. It boots the operating system and
starts the instrument firmware.
See Chapter 4.1.1, "Start Dialog", on page 31.
If the previous session ended regularly, the R&S NRX uses the settings from the
last session.
3. If you want to return to a defined initial state, perform a preset.
See "Preset" on page 134.
To switch off the R&S NRX
1. Press the on/standby key.
The R&S NRX saves its current settings for reuse in the next session and changes
into the standby state.
2. To power down the R&S NRX completely, set the AC power switch to position [0]
(Off).
