To connect the instrument and the external trigger source
1. Use a suitable cable to connect the external trigger source to the User 2 connector
of the R&S SMBV100B. See Figure 2-9 .
Figure 2-9: Simplified representation of a test setup**
** = The figure depicts the cabling as a general principle; particular test setups do not require all con-
nections at the same time
The Figure 2-9 depicts the location of the connectors and explains the connection
as principle. In practice, you would rather "substitute" the analyzer by a DUT, like a
base station (BS). Other than in the example, the DUT can be the source for the
reference signal. Instead of using an external trigger source, the DUT can also
send, for example, a frame trigger signal to the R&S
SMBV100B. The
R&S SMBV100B acts still as the signal source.
2. Use suitable cables to connect the RF and REF OUT connectors of the
R&S SMBV100B to the signal analyzer or the DUT.
Upon the receiving of an external trigger event, the R&S SMBV100B starts the sig-
nal generation and then generates a continuous signal. An "Arm" stops the signal
generation. A subsequent trigger event causes a restart of the signal generation.

2.3.4 Enabling and Configuring a Marker Signal
Test setups often require that an external device is synchronized to the generated data
stream. For this purpose, the R&S
SMBV100B can output marker signals (or markers)
also to the generated signal. The R&S SMBV100B provides several regular marker
