Remote Control Interfaces and Protocols
The R&S
ESRP supports different interfaces and protocols for remote control. The fol-
lowing table gives an overview.

) VISA is a standardized software interface library providing input and output functions to communicate with instruments. A VISA
installation on the controller is a prerequisite for remote control using the indicated interfaces.
11.2.4.1
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. 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 the programs to identify
and control the instrument.
The VISA resource string has the form:
TCPIP::host address[::LAN device name][::INSTR]
where:
●
TCPIP
designates the network protocol used
●
host address
is the IP address or host name of the device
●
LAN device name
defines the protocol and the instance number of a sub-instru-
ment;
–
inst0
selects the VXI-11 protocol (default)
–
hislip0
selects the newer HiSLIP protocol
