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 Typ e 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 211.
• 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 213.
• 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 214.
To set up Amplitude Modulation (AM)
In the Waveform Generator Modulation Menu (under [Wave Gen] > Settings >
Modulation):
1 Press the Ty pe 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
