2.2 Key Features
The R&S NRQ6 frequency selective power sensor sets standards in RF performance
and usability. Outstanding key features are:
●Combines the advantages of a measurement receiver (dynamic range, linearity &
video bandwidth) and a conventional diode-based or thermal power sensor (stabil-
ity, absolute accuracy & source match).
●Easy operation with features such as browser-based user interface, autoset config-
uration, 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.

3.1 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 damage,
immediately contact the carrier who delivered the power sensor. Make sure not to dis-
card 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 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
3.2 Operating Conditions
Specific operating conditions are required to ensure accurate measurements and to
avoid damage to the power sensor and connected devices. Before switching 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.

3.3 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.
3.4 Connecting to a DUT
The R&S NRQ6 has fan openings at both sides of the casing, as shown in Figure 4-1.
When connecting the R&S NRQ6 to a DUT and setting up the measurement 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 4.1, "RF Connector", on page 26.
1. Ensure that the RF connector of your DUT is compatible with the RF connector 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.
3.5 Connecting to a Power Supply
The power for the R&S NRQ6 is supplied over the LAN PoE+ interface. See also
Chapter 4.3, "LAN PoE+ Interface", on page 27.
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.

3.6.1.4 Establishing a Connection
There are two methods to establish a network connection:
●R&S NRQ6 and computer are connected to a common network
(infrastructure network).
●R&S NRQ6 and computer are connected only over the switch
(peer-to-peer network).
In both cases, you can address the R&S NRQ6 as follows:
●Chapter 3.6.1.5, "Using Hostnames", on page 20
●Chapter 3.6.1.6, "Assigning the IP Address", on page 21
To set up a network Ethernet connection
1. Connect the R&S NRQ6 to the network or to a single computer.

R&S®NRQ6
20User Manual 1178.3692.02 ─ 07
By default, the R&S NRQ6 is configured to use dynamic TCP/IP configuration
(DHCP) and to obtain the address information automatically.
If both LAN status LEDs are illuminated in green color, the R&S NRQ6 is correctly
connected to the network.
Note: Establishing a connection can take up to 2 minutes per device.
2. If the LAN status LEDs show another state, no connection is possible. For possible
solutions, see:
●Chapter 4.3, "LAN PoE+ Interface", on page 27
●Chapter 15.6, "Cannot Establish a LAN Connection", on page 206
3.6.1.5 Using Hostnames
In a LAN that uses a domain name system (DNS) server, you can address each com-
puter or instrument connected in the LAN using its unique hostname instead of the IP
address. The DNS server translates the hostname into the IP address. This is espe-
cially useful when using a DHCP server, as a new IP address can be assigned each
time the instrument is restarted.
The R&S NRQ6 is delivered with a default hostname that you can change.
Default hostname
The default hostname follows the syntax:
<device name>-<serial number>, where:
●<device name> is the short name of your R&S NRQ6.
For example, the <device name> of an R&S NRQ6 is nrq6.
●<serial number> is the individual serial number of the R&S NRQ6. The serial
number is printed on the bar code sticker at the rear side of the R&S NRQ6. It is
the third part of the device ID:
ID: 1421.3509K02 - 101441 - Zd Serial Number
Example:
Serial number of the R&S NRQ6: 101441
Default hostname: nrq6-101441
Hostname in zero configuration networks, including peer-to-peer networks
The R&S NRQ6 supports zero configuration networking, used in networks without
DHCP server, such as peer-to-peer networks. Thus, you can connect the R&S NRQ6
to a network without setting up services such as dynamic host configuration protocol
