5. Establish a network connection between the power sensor and the controlling

3.7.3.2 Establishing a connection to the network
There are two methods to establish a network connection:
Preparing for use
●
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).
In both cases, you can address the LAN power sensor as follows:
●
Chapter 3.7.3.3, "Using hostnames", on page 24
●
Chapter 3.7.3.4, "Assigning the IP address", on page 25
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 31
● "Troubleshooting for peer-to-peer connections" on page 24
23Getting Started 1419.0170.02 ─ 18
R&S®NRP Series
Connecting to a controlling host
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:
nrp18sn-101441
nrp18sn-101441.local
Preparing for use
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.
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 NRP18SN is nrp18sn.
●
<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:

R&S®NRP Series
Preparing for use
Connecting to a controlling host
ID: 1419.0035K02 - 101441 - Zd
Figure 3-6: Serial number on the name plate
Example:
Serial number of the power sensor: 101441
Default hostname: nrp18sn-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.
Serial Number
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.
Example:
Default hostname: nrp18sn-101441
Extended hostname: nrp18sn-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.
●
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 suc-
25Getting Started 1419.0170.02 ─ 18
R&S®NRP Series
Connecting to a controlling host
ceed 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 host-
names", on page 24.
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-topoint connection is used.

6 Remote control interfaces and protocols
For remote control, communication between the R&S NRP series power sensor
power sensors and the controlling host is established based on various interfaces
and protocols.
Depending on the power sensor type, the power sensors support different interfaces for remote control.
●
R&S NRP USB power sensors are always accessed using USB.
●
R&S NRP LAN power sensors can be accessed using USB or Ethernet.
Table 6-1 describes the protocols that are supported for each interface.

matically when the USB connection is established. Apart from the USBTMC driver
(which comes with the installation of the R&S NRP Toolkit), you do not have to
install a separate driver.
USB Test & Measurement Class Specification (USBTMC) is a protocol that is built
on top of USB for communication with USB devices. It defines class code information of the power sensor that identifies its functionality to load the respective
device driver. Using VISA library, it supports service request, triggers and other
operations that are commonly found in GPIB devices.
Besides USBTMC, the NRP legacy protocol is available to ensure the compatibility of the R&S NRP power sensors with the R&S NRP‑Z series of power sensors.
The usage of this protocol is not recommended for new applications.
The resource string represents an addressing scheme that is used to establish a
communication session with the power sensor. It is based on the power sensor
address and some power sensor- and vendor-specific information.
USB Resource String
The syntax of the used USB resource string is:
USB::<vendor ID>::<product ID>::<serial number>[::INSTR]
where:
●
<vendor ID> is the vendor ID for Rohde & Schwarz (0x0AAD)
●
<product ID> is the product ID for the Rohde & Schwarz power sensor
●
<serial number> is the individual serial number on the name plate at the rear
side of the power sensor

6.2 Ethernet interface
The Ethernet interface of the R&S NRP LAN power sensors allows you to integrate them in a local area network (LAN).
For remote control via a network, the computer and the power sensor must be
connected via the Ethernet interface to a common network with TCP/IP network
protocol. The TCP/IP network protocol and the associated network services are
preconfigured on the power sensor. Software for device control and the VISA program library must be installed on the computer.

6.2.1 VISA resource strings
The VISA resource string is required to establish a communication session
between the controller and the power sensor in a LAN. The resource string is a
unique identifier, composed of the specific IP address of the power sensor and
some network and VISA-specific keywords.
TCPIP::<IP address or hostname>[::<LAN device name>][::INSTR]
●
TCPIP designates the network protocol used
●
<IP address or hostname> is the IP address or host name of the device
●
[::<LAN device name>] defines the protocol and the instance number of a subinstrument:
●
[::INSTR] indicates the power sensor resource class (optional)
The IP address or hostname is used by the programs to identify and control the
power sensor. While the hostname is determined by settings in the power sensor,
the IP address is assigned by a DHCP server when the power sensor requests
one. Alternatively the IP address is determined with a procedure called Zeroconf.
You can also assign a LAN device name which defines the protocol characteristics of the connection. See the description of the VISA resource string below for
the corresponding interface protocols. The string of the LAN device name is
emphasized in italics.
HiSLIP
TCPIP::<IP address or hostname>::hislip0[::INSTR]
●
hislip0 is the HiSLIP device name, designates that the interface protocol
HiSLIP is used (mandatory)
hislip0 is composed of [::HiSLIP device name[,HiSLIP port]] and must be
assigned.
VXI-11
TCPIP::<IP address or hostname>[::inst0][::INSTR]
●
inst0 is the LAN device name, indicating that the VXI-11 protocol is used
(optional)
inst0 currently selects the VXI-11 protocol by default and can be omitted.
48Getting Started 1419.0170.02 ─ 18
R&S®NRP Series
Socket communication
TCPIP::<IP address or hostname>::port::SOCKET
●
port determines the used port number
●
SOCKET indicates the raw network socket resource class
Socket communication requires the specification of the port (commonly referred
to as port number) and of "SOCKET" to complete the VISA resource string with
the associated protocol used.
The default port for socket communication is port 5025.
Example:
A power sensor has the IP address 10.111.11.20; the valid resource string using
VXI-11 protocol is:
TCPIP::10.111.11.20::INSTR
Remote control interfaces and protocols
Ethernet interface
The DNS host name is nrp18sn-100001; the valid resource string is:
TCPIP::nrp18sn-100001::hislip0 (HiSLIP)
TCPIP::nrp18sn-100001::inst0 (VXI-11)
A raw socket connection can be established using:
TCPIP::10.111.11.20::5025::SOCKET
TCPIP::nrp18sn-100001::5025::SOCKET
