275 +**Primary Configuration Settings in iDAS**
266 266  
277 +These settings are integral to the operation of the iDAS system, significantly influencing aspects like the rate of data streaming. They encompass:
267 267  
279 +1. **Sampling Frequency:** Determines how often data is captured.
280 +1. **Spatial Resolution:** Defines the level of detail in spatial data.
281 +1. **Fiber Length:** Impacts the range over which data is collected.
268 268  
283 +In configuring these parameters, a balance must be struck. This involves aligning the system's physical capabilities, such as fiber length and spatial resolution, with the practical limits of data collection, including the volume of data generated. Adjusting these settings correctly is crucial for optimizing data quality while managing the data volume effectively. This balance ensures that the system meets the specific needs of each application without overwhelming storage or processing capabilities.
