R&S AFQ100A Connecting the R&S AFQ to a Network (LAN)
Configuring the R&S AFQ for Network Operation
The network interface functions with 10/100/1000Mbps Ethernet IEEE 802.3u. The TCP/IP network
protocol and the associated network services are preconfigured.
For data exchange in a LAN, each connected PC or instrument must be accessible via an IP address or
via an unambiguous computer name. In addition, network access of the different users is organized by
the assignment of access rights.
Access rights determine which of the available network resources, e.g. data logging systems, are
available to the R&S AFQ.
The Window XP operating system is protected by an activated firewall per default. The configuration of
the firewall has to be adapted according to the required network communication needs.
Networks using DHCP
The R&S AFQ is preconfigured for networks using DHCP (dynamic host configuration protocol). In
these networks, an available IP address is automatically assigned to the R&S AFQ. In this case the
generator is identified via an unambiguous computer name in the network.
Each R&S AFQ is assigned a individual computer name in the factory. This name can be queried and
changed in the Start - My Computer menu of Windows XP (see "Query Computer Name" below).
Networks using fixed IP addresses
In networks using fixed IP addresses, the addresses are mostly assigned by the network administrator.
A fixed IP address must be entered in the Start - Control Panel menu of Windows XP.
Point-to-Point Connection
To build a simple network - just an LAN connection between the R&S AFQ and a controller without
integration into a larger network - an IP address has to be assigned to the R&S AFQ and the controller.
For such purposes, the IP addresses 192.168.xxx.yyy are available .The value range for xxx and yyy is
1...254, the value for the subnet mask is always 255.255.255.0.
For this type of connection, a commercial cross-over RJ-45 cable is used.
User name and password
The user "instrument" is assigned to the R&S AFQ. The user name is used for auto-login when the
instrument is started and for manual remote-control. The password is also "instrument". By assigning
the respective rights, the network administrator decides which directories and resources in the network
can be accessed by the R&S AFQ.
