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.
Formula's General Format
Sin((2*pi*t*F
c
+ K*Sin(2*pi*t*F
M
))
Where
 F
c
– Carrier frequency in Hertz.
 K – Peak phase excursion in radians.
 F
M
– Modulation frequency in Hertz.
