4.7 Amplitude Modulation
Amplitude modulation provides a waveform in which the amplitude of the
carrier waveform varies with the modulating waveform.
Carrier Waveform
The default carrier waveform is sine. One may also choose from square,
ramp and arbitrary waveforms but not pulse, noise and dc waveforms.
The default carrier frequency is 1kHz for all waveforms. Each carrier
waveform has its own acceptable range of frequencies. Refer to the table
in Section 3.4 “To Set Output Frequency/Period” for details.
Modulating Waveform
Model 645 accepts either internal or external modulating source but not
both at the same time. The default source is internal, and the default
