The following configurations are rather theoretical cases, because you rarely use
the R&S
SMCV100B as a standalone instrument. Usually, the instrument would
be connected to a device under test (DUT) and/or other measurement equipment.

As a rule, whenever a test setup requires two or more devices, provide them with
a common reference frequency. Some test setups require control of the signal
generation start and an exact generation start time, determined by a defined trig-
ger event. For example, by triggering the instrument internally or externally from
the DUT.
The example below illustrates the general principle of external triggering and
extends the configuration performed in
Chapter 6.2, "Generating a Digitally Modu-
on page 39 by the configuration of the required trigger signal and
connector settings.
This test setup requires one signal analyzer, like the R&S
®
FSW, as additional
equipment.
