ATSC 3.0 : Recommended Practices
An ATSC Recommended Practice is a document that states specifications or criteria within Advanced Television Systems that are not strictly necessary for effective implementation and interoperability, but that are thought to be advisable and may improve the efficiency of implementation or reduce the probability of implementation errors. An ATSC Recommended Practice may specify preferred methodology for implementation and operation and may recommend a choice from among alternatives.

A/326, “ATSC 3.0 Field Test Plan”Most Recent Document Approved: 24 April 2023
This document presents the objectives of, and general methodology for, conducting field tests of the ATSC 3.0 over-the-air (OTA) terrestrial digital television (DTV) system. The physical layer of this DTV standard provides a comprehensive and flexible tool-box of configuration options and features for digital broadcast transmission, and allows broadcasters to pursue many different modulation and coding configurations. The intention of this document is to summarize and describe RF field environment performance test processes, and provide analysis for manufacturers attempting to verify functionality of their receiver’s physical layer design or for broadcasters trying to evaluate coverage and service in their market. This document should be used by manufacturers and broadcasters to ensure their field testing is conducted with a consistent methodology.
