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 R&S
FSW use port number 5025 for this pur-
pose. The port is configured for communication on a command-to-command basis and
for remote control from a program.
10.1.1.2
GPIB Interface (IEC 625/IEEE 418 Bus Interface)
A GPIB interface is integrated on the rear panel of the instrument. By connecting a PC
to the R&S
FSW via the GPIB connection you can send remote commands to control
and operate the instrument.
To be able to control the instrument via the GPIB bus, the instrument and the controller
must be linked by a GPIB bus cable. A GPIB bus card, the card drivers and the pro-
gram libraries for the programming language used must be provided in the controller.
The controller must address the instrument with the GPIB bus address (see
ter 10.5.1.5, "How to Change the GPIB Instrument Address"
set the GPIB address and the ID response string. The GPIB language is set as SCPI
by default and cannot be changed for the R&S
FSW.
Notes and Conditions
In connection with the GPIB interface, note the following:
●
Up to 15 instruments can be connected
●
The total cable length is restricted to a maximum of 15 m or 2 m times the number
of devices, whichever is less; the cable lenth between two instruments should not
exceed 2 m.
●
A wired "OR"-connection is used if several instruments are connected in parallel.
●
Any connected IEC-bus cables should be terminated by an instrument or controller.
10.1.1.3
USB Interface
For remote control via the USB connection, the PC and the instrument must be con-
nected via the USB type B 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 enter an address string or install a
separate driver.
USB address
The used USB address string is:
USB::<vendor ID>::<product ID>::<serial number>[::INSTR]
where:
●
<vendor ID> is the vendor ID for Rohde & Schwarz (0x0AAD)
●
<product ID> is the product ID for the Rohde & Schwarz instrument
●
<serial number> is the individual serial number on the rear of the instrument
