# Sp acquire.m

Soft pulse followed by acquisition. The soft pulse is simulated using the Fokker-Planck formalism. Syntax:

    fid=sp_acquire(spin_system,parameters,H,R,K)


Parameters:

    parameters.soft_frq - frequency of the soft pulse, Hz

parameters.soft_phi - phase of the soft pulse, rad

parameters.soft_pwr - power of the soft pulse, Hz

parameters.soft_dur - duration of the sof pulse, s

parameters.soft_rnk - Fokker-Planck cut-off rank

parameters.method   - method to use during the call
to shaped_pulse_af()


The last parameter should be increased until convergence is achieved in the output.
