The NFC/EVM option provides functionality to generate signals in accordance with the
short-range wireless connectivity technology NFC-A/B/F and the EMV standard.
For details, see the R&S SMWNFC A/B/F user manual.
DVB-H/T, DVB-S2/S2X
This digital standard requires an instrument equipped with the DVB options R&S SMW-
K52/-K116.
The DVB options provides functionality to generate signals in accordance with the digi-
tal video broadcasting standards DVB-H and DVB-S2/S2X.
For details, see the R&S SMW DVB-H/T, DVB-S2/S2X user manual.
4.5 Common Functions and Settings in the Baseband
Domain
Basic signal generation settings that are common to many generation tasks, regardless
of the selected baseband source or digital standard, are described here. If you are per-
forming a specific signal generation task, like generating a signal according to a digital
standard, be sure to check the specific description for settings that may deviate from
these common settings.

4.5.1.1 Data, Clock and Control Signals and Sources in the Baseband
This section describes the common characteristics of the signals used for generating
the baseband signal for all standards. Common characteristics do not depend on the
used generating mode (see Chapter 4.1, "Overview of the Signal Generation Modes",
on page 220). The selection in the dialogs at any given time depends on the parameter
and standard concerned. It is clear from the selection list offered in the dialog. Some
parameters are therefore not available in certain cases.
Characteristics which are uniquely specific to particular standards are described in the
corresponding user manual.
