Standard Radio Analyzer, unwanted correlations between different signal components
using different transmission standards can be detected. Thus, for example, an irregu-
larity in a GSM burst can be examined closer in the R&S
FSW 3G FDD BTS (W-
CDMA) slave application to reveal dependencies like a change in the EVM value.
Multi-Standard Real-Time mode
In order to combine the advantages of the MSRA mode with its correlated measure-
ments and the gapless results and frequency mask provided by real-time measure-
ments, a third operating mode has been introduced: the
Multi-Standard Real-Time
(MSRT) mode
. This operating mode is only available if one of the real-time options
(R&S
FSW-K160RE/-B160R/-B512R/-U160R/-U512R) is installed.
In this operating mode, data acquisition is performed once as a real-time measure-
ment, and the captured data is then evaluated by any number of slave applications.
Thus, a real-time measurement triggered with a frequency mask can be performed,
and the results can be evaluated in the VSA slave application, for example, to detect
the cause of a frequency exception.
Distinct operating modes
Although the applications themselves are identical in all operating modes, the handling
of the data between applications is not. Thus, the operating mode determines which
slave applications are available and active. Whenever you change the operating mode,
the currently active measurement channels are closed. The default operating mode is
Signal and Spectrum Analyzer mode; however, the presetting can be changed.

Switching between slave applications
When you switch to a new slave application, a set of parameters is passed on from the
current slave application to the new one:
●
center frequency and frequency offset
●
reference level and reference level offset
●
attenuation
After initial setup, the parameters for the measurement channel are stored upon exiting
and restored upon re-entering the channel. Thus, you can switch between slave appli-
cations quickly and easily.

The R&S
FSW provides some applications in the base unit while others are available
only if the corresponding firmware options are installed. Not all R&S
FSW applications
are supported in MSRA/MSRT mode.
