Connecting with the Instrument: VISA Address String
Only the IP address of the instrument is required to set up the connection. It identifies the
instrument in the network and is part of the resource string used by the programs to
identify and control the instrument. Depending on the communication mode - VXI-11
protocol or raw socket mode - the resource string has different forms.
IP address and port number are listed in the "Ethernet Settings" of R&S
RTM, see also:
chapter 15.1.2.2, "Configuring LAN Parameters"
If the LAN is supported by a DNS server, the host name can be used instead of the IP
address. The DNS server (Domain Name System server) translates the host name to the
IP address. To assign a host name to the R&S
RTM, select SETUP > "More" > "Device
Name".
VXI-11 protocol
TCPIP::<IP address>[::inst0]::INSTR
where:
●
inst0
is the LAN device name. VISA supports several devices running on the instru-
ment. On R&S
RTM, only one device is configured, so the LAN device name can be
omitted.
●
INSTR
indicates that the VXI-11 protocol is used
Example:
If the instrument has the IP address
192.1.2.3
, the valid resource string is:
TCPIP::192.1.2.3::INSTR
With host name instead of IP address:
TCPIP::<host name>[::inst0]::INSTR
Example:
If the computer name is
RSRT1
, the valid resource string is:
TCPIP::RSRT1::INSTR
.
