The American National Standards Institute has approved ANSI/SCTE 06 2015 "Composite Distortion Measurements (CSO & CTB)." The document describes a test procedure for the laboratory and production measurement of composite distortion products, composite second order (CSO) and composite triple beat (CTB). In order to obtain a stable, repeatable measurement, the test procedure describes testing performed with continuous wave (CW) carriers.
