Risk of device failure
The R&S SGU 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 123
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 SGU allows you to connect either a
USB device or use the R&S SGU 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 SGU,
the R&S SGU acts as a USB device.
To connect the controller to the USB interface of the R&S SGU, always connect the
USB type Micro-B connector to the R&S SGU. 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.
