Phase Modulation

PLEASE NOTE THE FOLLOWING:

At least one Direct Digital Synthesis (DDS) Channel must be in your
workspace for this example.

See steps 5 and 6 in Arbitrary Waveform Generator Setup Example
(on page 27) for details.

A phase modulation waveform. The actual formula used here is

Sin(2*3.141592*2*2*E6*t+(3.141592*Sin(2*3.141592*0.4*E6*t))). Set the time

to 10.000000µ to view the graph as previously shown.

Where

F

c

– Carrier frequency in Hertz.

K

– Peak phase excursion in radians.

F

M

– Modulation frequency in Hertz.
