Omfang

IEC 60728-4:2007 applies to system outlets, splitters and taps, passive single or multiple port equipment comprising filters, attenuators, equalizers, galvanic isolators, power injectors, cable splices, terminating resistors and transfer points, but excluding coaxial cables and receiver leads. This standard: - covers the frequency range 5 MHz to 3 000 MHz; - identifies performance requirements for certain parameters; - lays down data publication requirements for certain parameters; - stipulates methods of measurements; - introduces minimum requirements defining quality grades. This third edition cancels and replaces the second edition published in 2000, of which it constitutes a technical revision. It includes the following significant technical changes: Subclause 3.1 includes several new or modified definitions. Clause 4 includes added test methods for attenuation, isolation, through-loss, group delay variation, amplitude frequency response and two carrier intermodulation measurements for second- and third-order products. Clause 5 includes updated and new performance requirements.
