Remote Control
This chapter provides instructions on how to set up the R&S OSP for remote control, a
general introduction to remote control of programmable instruments, and the
description of the remote control concept. For reference information about all remote
control commands implemented by the instrument, complemented by comprehensive
programming examples, refer to
chapter 7
6.1 Remote Control Operation
The instrument provides a LAN remote control interface. The following table shows
details.

*)
VISA is a standardized software interface library providing input and output functions to communicate
with instruments. The I/O channel (LAN or TCP/IP, USB, GPIB, ...) is selected at initialization time by
means of the channel
–specific resource string (also termed address string) quoted above or by an
appropriately defined VISA alias (short name). A VISA installation is a prerequisite for remote control
over LAN or USB interface. For more information about VISA refer to the user documentation.
LAN Connection
The R&S OSP provides a LAN connector for direct connection to a Local Area
Network. Remote control via LAN requires a VISA installation but no additional
hardware at the controller. VISA provides the TCP/IP interface type and several
protocol types to communicate with LAN-connected devices. For a simple example
see Establishing and Testing a LAN Connection
SCPI (Standard Commands for Programmable Instruments) commands
– instrument-
control commands
– are used for remote control.
SCPI Compatibility
The SCPI standard (Standard Commands for Programmable Instruments) is based on
standard IEEE 488.2 and aims at the standardization of device-specific commands,
error handling and the status registers. The R&S OSP is compatible to the SCPI
version 1999.0.
SCPI-confirmed commands are explicitly marked in the command reference chapters.
