4 Set the modulating frequency.
Press the PWM Freq softkey and then set the value to 5 Hz using the numeric
keypad or the knob and cursor keys.
5 Select the modulating waveform shape.
Press the Shape softkey to select the shape of the modulating waveform. For
this example, select a sine wave.
At this point, the function generator outputs a PWM waveform with the
specified modulation parameters (if the output is enabled).
6View the waveform.
Press to view the waveform and parameters.
To turn off the Graph Mode, press again.
Of course, to really view the PWM waveform, you would need to output it to an
oscilloscope. If you do this, you will see how the pulse width varies, in this
case, from 80 to 120 μs. At a modulation frequency of 5 Hz, the deviation is
quite visible.
