Working with Modulation Types
Creating an FSK Modulation Type User File with the Frequency Values
Editor
Use this procedure to set the frequency deviation for data
00
,
01
,
10
, and
11
to
configure a user–defined FSK modulation.

Each time you enter a value, the
Data
column increments to the next
binary number, up to a total of 16 data values (from
0000
to
1111
). An
unstored file of frequency deviation values is created for the custom
4–level FSK file.

Modifying a Predefined FSK Modulation Type User File with the
Frequency Values Editor
Using the
Frequency Values
editor, you can define, modify, and store
user–defined frequency shift keying modulation. The
Frequency Values
editor is available for custom Real–Time I/Q Baseband mode, but is not
available for waveforms generated in custom Arb Waveform Generator mode.
Use this example to learn how to add errors to a default FSK modulation.
