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
noise, pulse, or dc as the carrier waveform.
• If you select an arbitrary waveform as the modulating waveshape,
the waveform is automatically limited to 8K points. Extra waveform
points are removed using decimation.
• Front-Panel Operation: After enabling FM, press the Shape softkey.
• Remote Interface Operation:
FM:INTernal:FUNCtion {SINusoid|SQUare|RAMP|NRAMp|
TRIangle|NOISe|USER}
Modulating Waveform Frequency
The function generator will accept an internal or external modulation
source for FM.
• Modulating frequency (internal source): 2 mHz to 20 kHz.
The default is 10 Hz.
• Front-Panel Operation: After enabling FM, press the FM Freq softkey.
• Remote Interface Operation:
FM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
