Modulating Waveform Shape
The waveform generator will accept an internal or external modulation
source for PWM.
• Modulating waveform shape (internal source): Sine (default), Square,
Pulse, UpRamp,
DnRamp, Triangle, Noise, or PRBS .
• Square has 50% duty cycle
• UpRamp has 100% symmetry
• Triangle has 50% symmetry
• DnRamp has 0% symmetry
• Noise - white gaussian noise
• PRBS - Pseudo Random Bit Sequence (polynomial PN7)
• You can use noise as the modulating waveshape, but you cannot use
noise, arbitrary waveforms, or DC as the carrier waveform.
• Front-Panel Operation: After enabling PWM, press the Shape
softkey.
• Remote Interface Operation:
