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.The documents are available for download at http://www.scte.org/standards/Standards_Available.aspx.
