4 In the Wave Gen Mod 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 209.
• 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 210.
• 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 212.
To set up Amplitude Modulation (AM)
In the Wave Gen Mod 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
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.
