Remote control interfaces and protocols
The instrument supports different interfaces for remote control. The following table
gives an overview.

Interface
Protocols, VISA address string
Remarks
Local Area
Network
(LAN)
Protocol HiSLIP
VISA address string:
TCPIP::<host address>::
hislip0[,<port>][::INSTR]
Protocol VXI-11
VISA address string:
TCPIP::<host address>[::
inst0]::[INSTR]
The LAN connector is located on rear panel of the
instrument.
The interface is based on TCP/IP and supports vari-
ous protocols.
GPIB (IEC/
IEEE Bus
Interface)
VISA address string:
GPIB::primary address[::INSTR]
(no secondary address)
The GPIB bus interface according to standard IEC
625.1/IEEE 488.1 is located on the rear panel of the
instrument.
The GPIB bus interface requires option R&S
RTO6-
B10.
Within this interface description, the term GPIB is used as a synonym for the IEC/IEEE
bus interface.
22.5.1.1
LAN interface
To be integrated in a LAN, the instrument is equipped with a LAN interface, consisting
of a connector, a network interface card and protocols. The interface details are given
in the specifications.
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. They are connected
using a commercial RJ45 cable (shielded or unshielded twisted pair category 5). The
TCP/IP network protocol and the associated network services are preconfigured on the
instrument. Software for instrument control and the VISA program library must be
installed on the controller.
IP address
Only the IP address or a valid DNS host name is required to set up the connection.
The host address is part of the "VISA resource string" used by programs to identify and
control the instrument. The VISA resource string has the form:
TCPIP::<host address>::hislip0[,<port>][::INSTR]
for HiSLIP protocol
TCPIP::<host address>[::inst0][::INSTR]
for VXI-11 protocol
Where:
●
host address
identifies the instrument in the network, usually the IP address. 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.
