Frequency Modulation (FM)

Modulating Waveform Shape
The function generator will accept an internal or external modulation
source for FM.
• Modulating waveform shape (internal source): Sine, Square, Ramp,
Negative Ramp, Triangle, Noise, or Arb waveform.
The default is Sine.
• Square has 50% duty cycle.
• Ramp has 100% symmetry.
• Triangle has 50% symmetry.
• Negative ramp has 0% symmetry.
• You can use noise as the modulating waveshape, but you cannot use
use ramp, pulse, noise, dc, or arbitrary as the carrier waveform.
• If you select an arbitrary waveform as the modulating waveshape,
the waveform is automatically limited to 4K points. Extra waveform
points are removed using decimation.
Note:
Arbitrary waveforms are optionally available with the 33210A
(Option 002). To upgrade your 33210A to include arbitrary waveform
functionality, go to
