Modulating Waveform Shape
The function generator will accept an internal or external modulation
source for PWM.
• 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.
• 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.
• Front-Panel Operation: After enabling PWM, press the Shape
softkey.
• Remote Interface Operation:
PWM:INTernal:FUNCtion {SINusoid|SQUare|
TRIangle|NOISe|USER}
Modulating Waveform Frequency
The function generator will accept an internal or external modulation
source for PWM.
• Modulating frequency (internal source): 2 mHz to 20 kHz.
The default is 10 Hz .
• Front-Panel Operation : After enabling PWM, press the PWM Freq
softkey.
• Remote Interface Operation:
PWM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
