.. index:: ModOsc
Traverse Field sinususodally modulated oscillation. Sinusoidal distribution of precession frequencies about bias e.g. from SDW.
A(t)=A_0 \cos(\omega t + \phi)J_0(\omega_\text{mod}t)
where,
A_0 is the amplitude,
\omega is the oscillation frequency,
phi is the phase,
and \omega_\text{mod} (G) is the modulation frequency.
