The simplest way to establish socket communication is to use the built-in telnet
program. The telnet program is part of every operating system and supports com-
munication with the software on a command-by-command basis.
Socket connections are established on a specially defined port. The socket
address is a combination of the IP address or the host name of the instrument
and the number of the port configured for remote-control. All instruments use port
number 5025 for this purpose. The port is configured for communication on a
command-to-command basis and for remote control from a program running on a
connected PC.

USB interface
For remote control via USB connection, the PC and the instrument must be con-
nected via the USB interface. A USB connection requires the VISA library to be
installed. VISA detects and configures the R&S instrument automatically when
the USB connection is established. You do not have to install a separate driver.
You can retrieve the USB resource string from the "SGMA-GUI > Instrument
Name > Setup > Remote" dialog.
Example:
USB::0x0AAD::0x00EC::100021::INSTR
0x0AAD is the vendor ID for Rohde
&
Schwarz.
0x00EC is the product ID for the R&S
SGT.
100021 is the serial number of the particular instrument.
7.2.1.3
PCI Express interface
A PCI Express (PCIe) connector is provided on the rear panel of the instrument.
Refer to chapter "Advanced Remote Control via PCIe" of the user manual for a
description of how to set up a remote control connection via PCIe and the permit-
ted cables.
Via PCI Express some commands can be sent to the instrument with optimized
speed (memory-mapped remote control), e.g. frequency or level settings. Speed
optimization allows minimum setup time.
You can retrieve the PCIe resource string from the "SGMA-GUI > Instrument
Name > Setup > Remote" dialog.
