17 Waveform Generator
3 In the Waveform Generator Settings Menu, press the Modulation softkey.
4 In the Waveform Generator Modulation Menu:
• Press the Modulation softkey to enable or disable modulated waveform
generator output.
You can enable modulation for all waveform generator function types except
pulse, DC, and noise.
• Press the Type softkey and turn the Entry knob to select the modulation type:
• Amplitude Modulation (AM) — the amplitude of the original carrier signal is
modified according to the amplitude of the modulating signal. See "To
set up Amplitude Modulation (AM)" on page 268.
• Frequency Modulation (FM) — the frequency of the original carrier signal is
modified according to the amplitude of the modulating signal. See "To
set up Frequency Modulation (FM)" on page 269.
• Frequency-Shift Keying Modulation (FSK) — the output frequency "shifts"
between the original carrier frequency and a "hop frequency" at the
specified FSK rate. The FSK rate specifies a digital square wave
modulating signal. See "To set up Frequency-Shift Keying Modulation
(FSK)" on page 271.
To set up Amplitude Modulation (AM)
In the Waveform Generator Modulation Menu (under [Wave Gen] > Settings >
Modulation):
1 Press the Type softkey and turn the Entry knob to select Amplitude Modulation
(AM).
2 Press the Waveform softkey and turn the Entry knob to select the shape of the
modulating signal:
• Sine
• Square
• Ramp
• Sine Cardinal
