To add modulation to the waveform generator output

Modulation is where an original carrier signal is modified according to the
amplitude of a second modulating signal. The modulation type (AM, FM, or
FSK) specifies how the carrier signal is modified.
Modulated waveforms are available on the WaveGen1 output.
To enable and set up modulation for the waveform generator output:
1 If the Waveform Generator Menu is not currently displayed on the
2 In the Waveform Generator Menu, press the Settings softkey.
3 In the Waveform Generator Settings Menu, press the Modulation softkey.
4 In the Waveform Generator Modulation Menu:

You can enable modulation for all waveform generator function types
except arbitrary, square, pulse, DC, noise, and Gaussian pulse.
Modulation is not available when waveform generator dual channel
tracking is being used.
