General Form (the PHASE parameter is only possible when XSPICE is enabled):

AM(VA VO MF FC TD PHASES)

Examples:

V1 12 0 AM(0.5 1 20K 5MEG 1m)

The shape of the waveform is described by the following equation:

[\begin{array}{ll} {V\left( t \right) = V_{A}\left( {VO + \sin\left( {2\pi \cdot MF \cdot t} \right) + PHASES} \right)\sin\left( {2\pi \cdot FC \cdot t + PHASES} \right)} & \ \end{array}]
