Frequency 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 frequency modulation waveform. The actual formula used here is
Sin(2*3.141592*2*E6*t+2*Cos(2*3.141592*0.4*E6*t)). Set the time to
10.000000µ to view the graph as previously shown.
