3 Key Features
The R&S NRQ6 frequency selective power sensor sets standards in RF perfor-
mance and usability. Outstanding key features are:
●Combines the advantages of a measurement receiver (dynamic range, linear-
ity & video bandwidth) and a conventional diode-based or thermal power sen-
sor (stability, absolute accuracy & source match).
●Easy operation with features such as browser-based user interface, autoset
configuration, automatic frequency tracking or spectral preview (signal check).
●Measurements in low RF level ranges that are beyond the range of classical
power meters. Faster measurements in the RF level range close to the lower
boundary of classical power meters.
●Frequency selective measurements with adjustable bandwidth including a
built-in ACLR measurement function
For a detailed specification, refer to the data sheet.

4.1 Unpacking and Checking the Power Sensor
Check the equipment for completeness using the delivery note and the accessory
lists for the various items. Check the R&S NRQ6 for any damage. If there is dam-
age, immediately contact the carrier who delivered the power sensor. Make sure
not to discard the box and packing material.
Packing material
Retain the original packing material. If the instrument needs to be transpor-
ted or shipped later, you can use the material to protect the control ele-
ments and connectors.
4.1.1 Accessory List
The R&S NRQ6 comes with the following accessories:
●Printed getting started manual
●Multilingual safety brochure
●CD-ROM
●Additive data sheet ref. China ROHS
4.2 Operating Conditions
Specific operating conditions are required to ensure accurate measurements and
to avoid damage to the power sensor and connected devices. Before switching

Preparing for Use
R&S®NRQ6
16Getting Started 1178.3705.02 ─ 07
on the power sensor, observe the information on appropriate operating conditions
provided in the basic safety instructions and the data sheet of the R&S NRQ6.
In particular, ensure the following:
●The power sensor 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.
4.3 Considerations for Test Setup
Preventing electrostatic discharge (ESD)
ESD is most likely to occur when you connect or disconnect a DUT.
►NOTICE! Risk of electrostatic discharge (ESD). Electrostatic discharge (ESD)
can damage the electronic components of the power sensor 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.
Considerations for Test Setup

Preparing for Use
R&S®NRQ6
17Getting Started 1178.3705.02 ─ 07
4.4 Connecting to a DUT
The R&S NRQ6 has fan openings at both sides of the casing, as shown in Fig-
ure 5-1. When connecting the R&S NRQ6 to a DUT and setting up the measure-
ment assembly, be careful to allow sufficient airflow.
Risk of damage due to insufficient airflow
If the R&S NRQ6 is run with insufficient airflow for a longer period, the
R&S NRQ6 overheats. Overheating can disturb the operation, even cause
damage and lead to wrong measurement results.
Make sure of the following:
●All fan openings are unobstructed.
●Airflow perforations are unimpeded.
●Minimum distance between the fan openings and any object is 10 cm.
To connect to the DUT
For connecting the R&S NRQ6 to a DUT, use the RF connector of the
R&S NRQ6. For details, see Chapter 5.1, "RF Connector", on page 32.
1. Ensure that the RF connector of your DUT is compatible with the RF connec-
tor of the R&S NRQ6.
2. Insert the RF connector straight into the RF output of your DUT. Take care not
to tilt it.

3. NOTICE! Risk of damaging the center pin of the RF connector. Only rotate the
hex nut of the RF connector. Never rotate the R&S NRQ6 itself.
Tighten the RF connector manually.
4. Tighten the RF connector using a torque wrench with the nominal torque of
1.36 Nm (12'' lbs) to ensure maximum measurement accuracy.

To disconnect from the DUT
1. NOTICE! Risk of damaging the center pin of the RF connector. Only rotate the
hex nut of the RF connector. Never rotate the R&S NRQ6 itself.
Carefully loosen the union nut at the front of the RF connector of the
R&S NRQ6.
2. Remove the R&S NRQ6.
4.5 Connecting to a Power Supply
The power for the R&S NRQ6 is supplied over the LAN PoE+ interface. See also
Chapter 5.3, "LAN PoE+ Interface", on page 33.
Risk of R&S NRQ6 damage
Make sure to use only PoE+ power sourcing equipment (PSE) as specified
in the IEEE 802.3at standard. Otherwise, the following consequences can
occur:
●If too much power is supplied, the R&S NRQ6 can get overheated which
can result in damage.
●If the supplied power is not sufficient, the R&S NRQ6 does not work
properly or not at all.
To connect to a LAN PoE+ interface
1. Use a suitable cable as described in Chapter 5.3, "LAN PoE+ Interface",
on page 33.
2. Connect one end of the cable to the LAN interface of the R&S NRQ6.
3. Connect the other end of the cable to one of the following:
● PoE+ port of a LAN switch:
See Chapter 4.6.1.1, "Setup with a PoE+ Ethernet Switch", on page 20.
● Output of a PoE+ injector:
See Chapter 4.6.1.2, "Setup with a PoE+ Injector and a Non-PoE+ Ether-
net Switch", on page 21.
