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
•
Frequency Modulation (FM)
— the frequency of the original
carrier signal is modified according to the amplitude of
the modulating signal. See
•
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
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.

Press the
AM Freq
softkey and turn the Entry knob to specify the frequency of
the modulating signal.
