Amplitude Modulation (AM)
A modulated waveform consists of a carrier waveform and a
modulating waveform. In AM, the amplitude of the carrier is varied by the
instantaneous voltage of the modulating waveform. The function generator will
accept an internal or external modulation source.
For more information on the fundamentals of Amplitude Modulation, refer to
Chapter 7, "Tutorial".
To Select AM Modulation
– The function generator will allow only one modulation mode to be enabled at a
time. For example, you cannot enable AM and FM at the same time. When you
enable AM, the previous modulation mode is turned off.
– The function generator will not allow AM to be enabled at the same time that
sweep or burst is enabled. When you enable AM, the sweep or burst mode is
turned off.
– Front-Panel Operation: You must enable AM before setting up any of the other
modulation parameters. Press and then select “AM” using the Type
softkey. The AM waveform is output using the present settings for the carrier
frequency, modulating frequency, output amplitude, and offset voltage.
– Remote Interface Operation: To avoid multiple waveform changes, enable AM
after you have set up the other modulation parameters.
