Enabling analysis of a survey source signal using a time-based visualization of the survey source signal

To enable analysis of a signal associated with surveying a subterranean structure, a processing system receives a time series of the signal associated with surveying the subterranean structure. A visualization of the time series is generated, where the visualization is a time-based representation of a characteristic of the signal. The visualization enables a determination of whether undesirable variations occur with the signal over time.
