16 Waveform Generator
• Exponential Rise
• Exponential Fall
When the Ramp shape is selected, a Symmetry softkey appears so that
you can specify the amount of time per cycle that the ramp waveform is
rising.
3 Press the AM Freq softkey and turn the Entry knob to specify the
frequency of the modulating signal.
4 Press the AM Depth softkey and turn the Entry knob to specify the
amount of amplitude modulation.
AM Depth refers to the portion of the amplitude range that will be used
by the modulation. For example, a depth setting of 80% causes the
output amplitude to vary from 10% to 90% (90% – 10% = 80%) of the
original amplitude as the modulating signal goes from its minimum to
maximum amplitude.
The following screen shows an AM modulation of a 100 kHz sine wave
carrier signal.
