PCIe switch connection of an R&S SGS and an R&S SGU
Figure 7-7: Connection of an R&S SGS and an R&S SGU through a PCIe switch
1. Connect the PCIe switch to a switched off computer with a single lane PCIe cable.
2. Connect the R&S SGS and the R&S SGU to the PCIe switch.
3. Switch on the R&S SGS and the R&S SGU.
Wait until the [POWER ON/STANDBY] keys are green and not blinking.
4. Switch on the computer.
5. On the computer start one of the following:
a) The R&S SGMA-GUI
b) An application program for remote control of the instruments
6. Manually (or remotely) activate the R&S SGU as an extension to the R&S SGS.
The logical connection between an R&S SGS and an R&S SGU is established by the
driver layer of a program (e.g. the R&S SGMA-GUI) or the library PCIeController.dll
(Linux: libpciecontroller.so) of a remote control program on the PC. Make sure that
such a program runs on the PC so that an R&S SGS is able to communicate with an
R&S SGU.
7.2.4 Extending R&S SGS with the R&S SGU
If you connect the R&S SGU to a compatible Rohde & Schwarz signal generator, you
need a controller. This controller talks to the signal generator and configures the
R&S SGU.
In the following example, the instrument the R&S SGMA-GUI software controls an
R&S SGS and an R&S SGU. The R&S SGU is equipped with the frequency option
R&S SGU-B120.
Configuring the R&S SGU
This step-by-step instruction describes how to configure the R&S SGU to upconvert a
CW signal. An R&S SGS generates the CW signal. As a prerequisite for this example
the R&S SGMA-GUI software has to be installed on a remote PC.
