PCIe switch connection of an R&S SGS and an R&S SGU
Figure 5-7: 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.
The [POWER ON/STANDBY] keys of both instruments have to be 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. Such a program
has to be running on the PC so that an R&S SGS is able to communicate with an R&S
SGU.
5.2.4 R&S SGU as an Extension to the R&S SGS
In case the R&S SGU is connected to a compatible R&S signal generator, a controller
only needs to talk to the signal generator which in turn takes care of the proper settings
for the R&S SGU.
In the following example, the instrument is manually operated via the R&S SGMA-GUI
software. The R&S SGU in this example is a base unit equipped with the frequency
option R&S SGU-B120.
Configuring the R&S SGU to upconvert a CW signal generated by the R&S SGS
As a prerequisite for this example the R&S SGMA-GUI software has to be installed on
a remote PC.
