Custom Digital Modulation (Option 431)
Using the Arbitrary Waveform Generator
Creating a Custom TDMA Digital Modulation State
In this procedure, you learn how to set up a single–carrier NADC digital modulation with customized
modulation type, symbol rate, and filtering.

This softkey
sets the filter
bandwidth
parameter,
alpha. The
default Alpha
value changes
with the
modulation
standard (see
page271) and
modulation
type selected
(see
page259).
For details on each key, use key help as described on page 42.
This softkey sets
the filter shape.

Opens a menu where the
user–defined I/Q
constellations or
user–defined FSK frequency
mappings can be inserted
into a table and then applied
to the current modulation
type. Also; for both I/Q and
FSK, differential state
mapping can be specified.
