9.10 Extension
Depending on the installed option, your R&S SGS generates an RF signal with fre-
quency range up to 12.75 GHz. Some test cases, however, require even higher fre-
quencies. A general setup would thus include an upconverter connected to the signal
generator and you would have to control both the signal generator and the
upconverter.
The R&S SGS equipped with one of the options R&S SGS-B112/B112V provides the
build-in extension mode for controlling the R&S SGU upconverter. If you connect an
R&S SGU to the R&S SGS, this upconverter acts as an extension to your instrument
extending its frequency range to 20 GHz for instance. Refer to Chapter 7.2, "Connect-
ing an R&S SGS and an R&S SGU", on page 48 for a description of the possible set-
ups.
The extension mode provides the following advantages:
●
Simplified calibration of the R&S SGU and single point of control
In this setup, a controller does not need to access the extension, i.e. the R&S
SGU, directly. Instead, the R&S SGS acts as a controller to it and depending on the
required output signal parameters performs all required settings automatically.
The signal generator settings of the extension are disabled for direct configuration
in the R&S SGMA-GUI. However, you can still remotely control the extension using
the corresponding SCPI commands.
●
Extended value ranges and functionality
The main application field of the extension mode is the extended frequency range
but you can also benefit from the I/Q modulation and pulse modulation functions of
the extension. For frequencies greater than 12.75 GHz, the combination of R&S
SGS and R&S SGU can generate vector modulated signals even if the R&S SGS
is not equipped with the required options R&S SGS-B106V/B112V.
Prerequisites and required physical connections for operation in extension mode:
●
The R&S SGS is equipped with one of the options R&S SGS-B112/B112V.
