Sine (SINusoid), Square (SQUare), Ramp (RAMP) or Noise (NOISe) can be selected
as the modulating waveform. You can set the frequency of the modulating
waveform by sending [:SOURce[<n>]]:MOD:AM:INTernal:FREQuency
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency.
Sending the [:SOURce[<n>]]:MOD:TYPe
AM: amplitude modulation. The amplitude of the carrier waveform varies with the
amplitude of the modulating waveform.
FM: frequency modulation. The frequency of the carrier waveform varies with the
amplitude of the modulating waveform.

When the modulating waveform amplitude reaches its maximum, the carrier
waveform frequency increases by the "frequency deviation". When the modulating
waveform amplitude reaches its minimum, the carrier waveform frequency
decreases by the "frequency deviation".
