17 Waveform Generator
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.
To set up Frequency Modulation (FM)
In the Waveform Generator Modulation Menu (under [Wave Gen] > Settings >
Modulation):
1 Press the Type softkey and turn the Entry knob to select Frequency Modulation
(FM).
2 Press the Waveform softkey and turn the Entry knob to select the shape of the
modulating signal:
• Sine
• Square
• Ramp
• Sine Cardinal
