Duty Cycle Modulation Area
This section allows defining the modulation law of the duty cycle of the
pulse waveform by setting the modulating parameters.
The following fields are available:
 Frequency [Hz] - Set the frequency of the duty cycle modulating
waveform from 10uHZ to 6.67MHz depending on the pulse
waveform frequency.
If you change the Frequency of the pulse waveform, it automatically
updates the duty cycle modulating waveform frequency to have the
minimum % error and also updates the min-max range. The rounded
off frequency value is shown on the Resulting freq. [Hz] field.
 Period[s]/Frequency[Hz] - Click the Period(s) button if you want to
define the duty cycle modulating waveform by its period.
 Shape - The shape of the modulation waveform. Available options
include sine, triangle, ramp, white noise and manual. In manual
mode you can run-time change the Duty Cycle percentage rotating
the knob control.
