5. Establish a network connection between the power sensor and the controlling host.
3.6.3.2 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).
20User Manual 1177.6023.02 ─ 07
R&S®NRPxxT(N)
Preparing for Use
Connecting to a Controlling Host
●
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 3.6.3.3, "Using Hostnames", on page 21
●
Chapter 3.6.3.4, "Assigning the IP Address", on page 22
To set up a network Ethernet connection
1. Connect the power sensor as described in Chapter 3.6.3.1, "Connecting a LAN
Power Sensor to the LAN", on page 18.
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 27
● "Troubleshooting for peer-to-peer connections" on page 21
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 remaining main network adapter has been assigned an IP address
starting 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 are guaranteed
to 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:
nrp18tn-101441
nrp18tn-101441.local
3.6.3.3 Using Hostnames
In a LAN that uses a domain name system (DNS) server, each connected computer or
instrument can be accessed via an unambiguous 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.
21User Manual 1177.6023.02 ─ 07
R&S®NRPxxT(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 sensor.
For example, the <device name> of R&S NRP18TN is nrp18tn.
●
<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 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: nrp18tn-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: nrp18tn-101441
Extended hostname: nrp18tn-101441.local
3.6.3.4 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.
22User Manual 1177.6023.02 ─ 07
R&S®NRPxxT(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 use 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 sensor
In networks using a DHCP server, it is recommended that you address the sensor by
its unambiguous hostnames, see Chapter 3.6.3.3, "Using Hostnames", on page 21.
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.
