System Configuration > Fading/Baseband Configuration
Available are the standard settings and the following parameter, dedicated for the
option R&S
SMW-K550.
Duplicate Streams ← System Configuration > Fading/Baseband Configuration
(requires option R&S
SMW-K550)
This parameter is enabled in the configurations 3x1x1 and 4x1x1.
In a 3x1x1 configuration for example, there are (per default) 3 basebands and 3
streams. The first two basebands can generate signals with real-time data sources.
If "Duplicate Streams > On", created is a copy of each stream after baseband / fading
block. Generated are 6 streams; 4 of them can use real-time data sources, for example
to ensure non-truncated PN sequences.
The pair of streams created out of the same baseband are identical, in terms of con-
tent, power level and frequency. The streams are treated as individual streams in
terms of adding AWGN and shifting within the available RF bandwidth.
This feature is useful, if your test setup requires a combination of max 4 signals with
real-time data source and 4 ARB signals. For example, for performing GSM AM sup-
pression tests according to 3GPP TS 51.021, chapter 8.
