3.3 Considerations for test setup
Preparing for use
Connecting to a DUT
Give particular attention to the following aspects when handling power sensors.
EMI impact on measurement results
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF and interface
cables.
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.
Signal input and output levels
Information on signal levels is provided in the data sheet. Keep the signal levels within
the specified ranges to avoid damage to the product and connected devices.
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
NOTICE! Electrostatic discharge can damage the electronic components of the
►
product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
3.4 Connecting to a DUT
For connecting the power sensor to a DUT, use the RF connector. See Chapter 4.1,
"RF connector", on page 26.
To connect to the DUT
1. Ensure that the RF connector of your DUT is compatible with the RF connector of
the power sensor.
See Table 4-1.
2. Inspect both RF connectors carefully. Look for metal particles, contaminants and
defects.
If either RF connector is damaged, do not proceed, because the risk of damaging
the mating connector is too high.

SMART SENSOR TECHNOLOGY
NRP
The electrical power for the R&S NRPxxA(N) is supplied over one of the following interfaces:
●
Host interface
See Chapter 4.3, "Host interface", on page 27.
●
LAN PoE interface
Available only for LAN power sensors. See Chapter 4.5, "LAN PoE interface",
on page 28.
If you use the Ethernet interface of the LAN power sensors, you have to provide the
electrical power by power over Ethernet (PoE). In this case, you cannot provide the
electrical power over the host interface instead.
Choose the PoE power sourcing equipment (PSE) with care
Only use PoE power sourcing equipment (PSE) as specified in the IEEE standards
802.3af or IEEE 802.3at. Otherwise, the following can happen:
●
If too much power is supplied, the LAN power sensor can get overheated and
become damaged as a result.
●
If the supplied power is not sufficient, the LAN power sensor does not work properly or not at all.

Preparing for use
Connecting to a controlling host
Requires a power sensor with networking capabilities, a LAN power sensor.
Depending on the available equipment, you can choose from different ways to connect
a LAN power sensor to a controlling host.
The Ethernet interface of a LAN power sensor requires PoE (power over Ethernet).
See Chapter 4.5, "LAN PoE interface", on page 28.
Electromagnetic interference (EMI) can affect the measurement results. To avoid any
impact, use category 5 cables or better.

3.7.3.2 Establishing a connection to the network
There are two methods to establish a network connection:
●
Power sensor and controlling host are connected to a common network
(infrastructure network).
●
Power sensor and controlling host are connected only over the switch
(peer-to-peer network).
22User Manual 1177.6017.02 ─ 09
R&S®NRPxxA(N)
Preparing for use
Connecting to a controlling host
In both cases, you can address the LAN power sensor as follows:
●
Chapter 3.7.3.3, "Using hostnames", on page 23
●
Chapter 3.7.3.4, "Assigning the IP address", on page 24
To set up a network Ethernet connection
1. Connect the power sensor as described in Chapter 3.7.3.1, "Connecting a LAN
power sensor to the LAN", on page 20.
By default, the power sensor 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 power sensor 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:
● "Network status LED" on page 28
● "Troubleshooting for peer-to-peer connections" on page 23
Troubleshooting for peer-to-peer connections
1. Allow a waiting time, especially if the computer was used in a network before.
2. Check that only the main network adapter is active on the computer. If the computer has more than one network interfaces, explicitly disable all other network
interfaces if you plan to utilize a peer-to-peer connection to the power sensor.
3. Check that the IP address assigned to the remaining main network adapter starts
with 169.254. The IANA (Internet assigned numbers authority) has reserved the
range 169.254.0.0 to 169.254.255.255 for the allocation of automatic private
IP addresses (APIPA). Addresses from this range assuredly cause no conflicts with
any routable IP address.
4. Try to establish a connection to the power sensor with both the default hostname
and the hostname extended with .local, for example:
nrp6an-101441
nrp6an-101441.local
3.7.3.3 Using hostnames
In a LAN that uses a domain name system (DNS) server, each connected computer or
instrument can be accessed via a unique hostname instead of an IP address. The DNS
server translates the hostname to the IP address. Using the hostname is especially
useful when a DHCP server is used, as a new IP address can be assigned each time
the instrument is restarted.
Each power sensor is delivered with a default hostname assigned. You can change the
default hostname.
23User Manual 1177.6017.02 ─ 09
R&S®NRPxxA(N)
Preparing for use
Connecting to a controlling host
Default hostname
The default hostname follows the syntax:
<device name>-<serial number>, where:
●
<device name> is the short name of your power sensor.
For example, the <device name> of R&S NRP18AN is nrp6an.
●
<serial number> is the individual serial number of the power sensor. The serial
number is printed on the name plate at the rear side of the power sensor. It is part
of the device ID printed above the barcode:
ID: 1419.0035K02 - 101441 - Zd
Figure 3-6: Serial number on the name plate
Example:
Serial number of the power sensor: 101441
Default hostname: nrp6an-101441
Hostname in zero configuration networks, including peer-to-peer networks
The power sensor supports zero configuration networking, used in networks without
DHCP server, such as peer-to-peer networks. Thus, you can connect the power sensor
to a network without setting up services such as dynamic host configuration protocol
(DHCP) and domain name system (DNS), or configuring the network settings manually.
For establishing a connection to the power sensor, try the default hostname and the
hostname extended with .local as shown in the example below. All communication
for resolving names in the top-level-domain (TLD) .local are defined to be executed
using dedicated local services and ports if no other DNS (domain name server) is
available.
Serial Number
Example:
Default hostname: nrp6an-101441
Extended hostname: nrp6an-101441.local
3.7.3.4 Assigning the IP address
Depending on the network capabilities, the TCP/IP address information for the LAN
power sensor can be obtained in different ways:
●
If the network supports dynamic TCP/IP configuration using the dynamic host configuration protocol (DHCP), the address information can be assigned automatically.
24User Manual 1177.6017.02 ─ 09
R&S®NRPxxA(N)
Preparing for use
Connecting to a controlling host
●
If the network does not support DHCP, the LAN power sensor tries to obtain the IP
address via the zeroconf (APIA) protocol. If this attempt does not succeed or if the
instrument is set to using alternate TCP/IP configuration, the IP address must be
set manually.
For a description on how to set the IP address manually, refer to the user manual.
Use hostnames to identify the power sensor
In networks using a DHCP server, it is recommended that you address the power sensor by its unique hostname, see Chapter 3.7.3.3, "Using hostnames", on page 23.
A hostname is a unique identifier of the power sensor that remains permanent as long
as it is not explicitly changed. Hence, you can address a power sensor by the same
identification, irrespectively if a network or a point-to-point connection is used.
