Figure 2-10: Simplified representation of a test setup**
** = The figure depicts the cabling as a general principle; in a particular test setup not all connections
are required at the same time
The Figure 2-10 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). The DUT is the source for the reference signal and sends for
example a frame trigger signal to the R&S SMW, the R&S SMW acts still as the
signal source.
