The American National Standards Institute has approved four new SCTE standards, primarily dealing with test and measurement.

ANSI/SCTE 119 2011, Measurement Procedure for Noise Power Ratio, defines a method of measurement for noise power ratio (NPR) of active cable equipment. It is intended for measurement of 75-ohm devices having type "F" or 5/8-24 KS connectors.

ANSI/SCTE 125 2011, Hard Line Pin (plug) Connector Return Loss, describes a procedure to measure the return loss characteristics of a single mainline pin connector interfaced between (1) mainline cable and a precision airline. It implements the time domain-gating features of the network analyzers, which removes the interfaces, and far end termination from the DUT (device under test) measurement.

SCTE 14 2011, Test Method for Hex Crimp Tool Verification/Calibration, is intended to determine and verify the actual crimp dimension of hex crimp tools, measurement technique for determining the final hex size that may affect pull-off performance of the cable-to-connector interface, and calibration technique for adjusting hex crimp tools.

SCTE 115 2011, Test Method for Reverse Path (Upstream) Intermodulation Using Two Carriers, defines a method of measurement of intermodulation distortion in the return path.
