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.
5.5 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.

5.5.1.1 Data, Clock and Control Signals and Sources in the Baseband
This section describes common characteristics of the signals used for generating the
baseband signal for all standards. Common characteristics do not depend on the used
generation mode.
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 specific to particular standards are described in the corresponding user
manual.
For the generation of modulation signals, the instrument uses the following input sig-
nals:
●
Internal Modulation Data
●
External Modulation Data
●
Clock Signals
●
Control Signals
