In this example, we use the global USER connectors. Alternatively, you can achieve
the same configuration goal with the local T/M/C connectors.
This test setup requires one oscilloscope, like the R&S
®
RTO, as additional equipment.
1. In the block diagram, select "Block Diagram > Baseband > Misc > Custom Digital
Mod > Marker" tab.
2. Select "Marker Mode > Marker 1 > Pulse" and "Divider = 32".
Generated is a periodic marker with marker frequency of 120 KHz. The signal is
output at the USER 1 connector of the R&S SMW (see Figure 3-13).
3. Use a suitable cable to connect the USER 1 connector of the R&S SMW to the
monitoring instrument, for example oscilloscope like R&S
®
RTO, see Figure 3-15.

3.3.5 Routing a Baseband Signal to the Outputs
This section emphasizes on the signal routing capabilities in the default state of the
instrument (standard system configuration mode). The R&S SMW provides the "I/Q
Stream Mapper" function to route and distribute each of the generated I/Q signals
(streams) to any of the available output connectors.
In the provided example, you use the R&S SMW to generate two baseband signals,
apply a baseband frequency shift, weight them and add them. You then route the gen-
erated stream and define the output connector. The initial situation is the configuration
