7.2 Ethernet Interface
The Ethernet interface of the R&S NRQ6 allows you to integrate it in a local area
network (LAN).
Requirements
●
TCP/IP network protocol
The local area network must support the TCP/IP network protocol.
The TCP/IP network protocol and the associated network services are precon-
figured on the R&S
NRQ6.
●
VISA library
Installed on the computer.
●
Software for device control
Installed on the computer.
Setup
1. Using the Ethernet interface, connect the computer and the R&S NRQ6 to a
local area network, see Chapter 4.6.1, "Computer Using a LAN Connection" ,
on page 19.
2. Make sure that the R&S NRQ6 is powered by PoE+. For details, see
"R&S NRQ6 requires PoE+" on page 33.
7.2.1 VISA Resource Strings
The VISA resource string for network device communication is required to estab-
lish 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 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 hostname of the device
●
[::<LAN device name>] defines the protocol and the instance number of a sub-
instrument:
●
[::INSTR] indicates the power sensors resource class (optional)
