# BasebandCustomSourceTime
BasebandCustomSourceTime uses a user-supplied real baseband waveform with no carrier modulation.

# Formula
Let be the real envelope stored in source_time_dataset. The source is:
The envelope is interpolated to simulation time steps. Values outside the provided time range use the nearest endpoint value.
# Parameters
source_time_dataset: Dataset defining the real baseband waveform .
- Required field
amplitude: Real-valued amplitude scaling factor.
- Default: 1
phase: Locked to 0 for baseband source times.
