# DAS-Specific Constants Module Documentation

## 1. Purpose

This module provides hardware-specific constants and capability detection logic for various Data Acquisition System (DAS) devices within the DTS ecosystem. Each class encapsulates the unique characteristics of a specific DAS model—including maximum anti-aliasing filter rates, protocol version thresholds for feature enablement, and runtime capability queries for recording modes, streaming profiles, and clock synchronization options. This abstraction allows higher-level code to query device capabilities without hardcoding hardware-specific logic throughout the codebase.
