R&S FSP Instrument Functions
LAN Interface - Option R&S FSP-B16
4.10 LAN Interface - Option R&S FSP-B16
The instrument can be connected to an Ethernet LAN (local area network) using the
LAN interface connector on the rear panel. This makes it possible to transfer data
over the network and to use network printers. In addition, the instrument can be
remote-controlled via the network.
For details, refer to the Quick Start Guide chapters 2 , “ Preparing for Use” , 6 , “ LAN
Interface” .
4.10.1 NOVELL Networks
The operating system NETWARE from NOVELL is a server-based system. Data
cannot be exchanged between individual workstations; data transfer takes place
between the PC and a server. This server provides memory space and the connec-
tion to network printers. On a server, data is organized in directories as under DOS
and mapped to the workstation as virtual drives. A virtual drive behaves like an addi-
tional hard disk on the workstation, and the data can be edited accordingly. Network
printers can also be addressed like normal printers.
There are two versions of the NOVELL network operating system: bindery-based
(NETWARE 3) and NDS-based (more recent versions of NETWARE). With the older
version (NETWARE 3), each server manages its resources on its own and is inde-
pendent. A user must be managed on each server separately. In the case of NDS-
based versions, all resources in the network are managed together in the NDS
(NOVELL DIRECTORY SERVICE). The user must log into the network only once
and is given access to the resources according to his/her access rights. The individ-
ual resources and users are managed as objects in a hierarchical tree (NDS TREE).
The position of the object in the tree is referred to as "CONTEXT" with NETWARE
and must be known for access to the resources.
4.10.2 MICROSOFT Network
In case of a MICROSOFT network, data can be exchanged both between worksta-
tions (peer to peer) and between workstations and servers. The latter can supply
access to files and connection to the printers. On a server, data is organized in
directories as under DOS and mapped to the workstation as virtual drives. A virtual
drive behaves like an additional hard disk on the workstation, and the data can be
edited accordingly. Network printers can also be addressed like normal printers. A
connection is possible to DOS, WINDOWS FOR WORKGROUPS, WINDOWS95/
98/ME, WINDOWS NT/XP.
4.10.3 Remote Data Transfer with TCP/IP Services
The protocol TCP/IP allows the transfer of files between different computer systems.
This requires a program running on the two computers that controls this data trans-
fer. It is not necessary that the same operating or file system is used by both com-
puters. For example, a file transfer between DOS/WINDOWS and UNIX is possible.
One of the two partners must be configured as Host and the other one as Client.
However, they may change their roles. Usually, the system which is able to perform
several processes at the same time will play the host role. The file transfer program
usually used under TCP/IP is FTP (File Transfer Protocol). An FTP host is installed
as standard on the majority of UNIX systems.
