Remote Control via LAN Interface
For remote control via a network, the PC and the instrument must be connected via the LAN interface to
a common network with TCP/IP network protocol.
Connection of the Signal Generator to a network and the querying of a computer name is described in
section "Connection to the Network".
Software for instrument control and the VISA program library must be installed on the controller.
Instrument control is via the VXI-11 standard protocol.
Only the IP address or the computer name is required for link setup. The IP address/computer name is
part of the "visa resource string" used by the programs for identification and control of the instrument.
The visa resource string has the form:
TCPIP::ipaddr::inst0::INSTR
ipaddr has to be replaced by the IP address or the computer name of the instrument.
For instance, if the instrument has the IP address 192.1.2.3, TCPIP::192.1.2.3::inst0::INSTR is the valid
resource name. Specification of inst0 in the resource name is optional. In this example, also
TCPIP::192.1.2.3::INSTR is therefore a valid resource name.
A resource name with computer name could be TCPIP::RSSM1::INSTR, for instance.
TCPIP designates the network protocol used and INSTR indicates that the VXI-11 protocol is used.
If several instruments are connected to the network, each instrument has its own IP address and
associated resource name. The controller identifies these instruments by means of the resource name.
In the example below, the program 'Measurement & Automation Explorer' from National Instruments is
used for setting up an Ethernet remote-control link. Link setup with this program is easy and first tests
can be performed. The R&S Signal Generator is preconfigured for networks using DHCP (dynamic host
configuration protocol). If this configuration is used, the computer name must be entered at the position
of the IP address. It is also possible to assign a fixed IP address to the instrument.
Setting up Control of the Signal Generator in the 'Measurement & Automation
Control' Program.
! Start program on the controller
! Open the Create new menu with the right mouse key.
