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).
6 View 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
µ
s. At a modulation frequency of 5 Hz, the
deviation is quite visible.
