Note: This step is performed automatically on the first start and can also be omit-
ted for instruments with a direct LAN connection to the computer.
All instruments are added automatically to the main panel of the SIGMA-GUI.
2.3.3 Connecting a Controller via PCI Express
A PCI Express connector is provided on the rear panel of the instrument, see Chap-
ter 3.2, "Rear Panel Tour", on page 33.
Risk of device failure
The R&S SGS is equipped with a single lane PCIe interface that supports hot plugging.
Do not connect an external PC to the PCIe connector of the instrument during opera-
tion if this external PC does not support hot-plugging!
Using the PCIe interface for remote control of the instrument requires extended knowl-
edge. Refer to Chapter 10.3, "Advanced Remote Control Using PCIe", on page 172
for detailed information.
2.3.4 Connecting a Controller or a USB Device via USB
The USB interface on the rear panel of the R&S SGS allows you to connect either a
USB device or use the R&S SGS as a device and connect it to a controller.
Connecting a controller (host PC or compatible signal generator)
If you connect a controller (host PC or compatible signal generator) to the R&S SGS,
the R&S SGS acts as a USB device.
To connect the controller to the USB interface of the R&S SGS, always connect the
USB type Micro-B connector to the R&S SGS. Refer to the documentation of the con-
troller to find out which USB connector type you can connect to the controller.
The Figure 2-1 illustrates schematically the required connector type to emphasize on
the different connector shape.

An external PC with installed R&S SGMA-GUI is required for manual operation of the
R&S SGS.
