OQPSK
This softkey appears in two different situations, enabling you to either
select a modulation, or load an I/Q map into the I/Q table editor.
Selecting an OQPSK Modulation
Press this softkey to select OQPSK (offset quadrature phase shift
keying) for modulating a continuous stream of the selected data
pattern. OQPSK modulation transmits data at the rate of 2 bits per
symbol. The modulation selection appears in the
Mod Type
field in the
text area of the display, and under the
Select
,
QPSK and OQPSK
, and
PSK
softkeys in the Modulation Type menus.

Loading an OQPSK I/Q Map into the I/Q Table Editor
Press this softkey to load a OQPSK (offset quadrature phase shift
keying) I/Q map into the I/Q table editor. For details on editing I/Q
maps, see “
