Executive Summary
Test Procedure for Noise Figure (NF) of Active equipment used in Broadband networks. In this document two methods to measure noise figure will be covered: Y-factor and Gain or cold source.
Scope
This procedure defines two methods of measurement for Noise Figure of active Cable Telecommunications equipment. It is intended for measurement of 75 Ω devices having type “F” or 5/8-24 KS connectors, and for the measurement of true broadband noise as opposed to narrowband disturbances.
Test equipment characteristics limit this procedure to frequencies no lower than 10 MHz.
Benefits
Two standard methods of testing and measuring noise figure of active devices.
Intended Audience
Manufacturers and technical operations.
