Test Method for Reverse Path (Upstream) Intermodulation Using Two Carriers

Cable Communication Systems are two-way systems with signal generation and transmission in both forward and reverse directions. Test methods are required to determine the quality of the components used for this signal transmission in both directions.

This test procedure focuses on the reverse path and provides a method of measurement to evaluate the level intermodulation distortion generated by components used in the reverse path of the cable system.
