Direct 1

Synchronizes the acquired and reference waveforms assuming that sample rate is sufficient to prevent aliasing in intermediate operations. This method is recommended when the measurement sampling rate is high.
Alias Protected 2

Synchronizes the acquired and reference waveforms while ascertaining that intermediate operations are not impacted by aliasing. This method is recommended for non-contiguous carriers separated by a large gap, and/or when the measurement sampling rate is low. Refer to AMPM concept help for more information.
