KS X 3123 Update by RRA: Simpler Tests for Satellite Mobile Equipment

-

South Korea’s National Radio Research Agency (RRA) has announced a partial revision to the Conformity Assessment Test Methods for Radio Equipment (KS X 3123). The revision applies specifically to radio equipment used for mobile satellite communication and took effect on June 16, 2025.


The purpose of this revision is to reduce the workload for test laboratories and to prevent confusion during the test implementation process. To achieve this, certain test items have been simplified, and new detailed test procedures have been added.


The key changes include simpler environmental condition tests and updated references for equipment names and electrical test items. In addition, new test procedures have been established for each relevant technical requirement. These include frequency tolerance, antenna feed power, occupied bandwidth, spurious emissions limits, receiver spurious emissions, and fault detection functions.


This revised test method will stay in effect until the amendment to the national standard (KS) is completed.
