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::0x0088::100021::INSTR
0x0AAD is the vendor ID for Rohde&Schwarz
0x0088 is the product ID for the R&S
SGS
100021 is the serial number of the particular instrument
5.2.1.3
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. This
allows minimum setup time.
You can retrieve the PCIe resource string from the "SGMA-GUI > Instrument
Name > Setup > Remote" dialog.
Example:
PCIe::0x162f::0x132e::100021::INSTR
0x162f is the vendor ID for Rohde&Schwarz
0x132e is the product ID for the R&S
SGS
100021 is the serial number of the particular instrument
