ANSI SCTE 45-2017 pdf free download – Test Method for Group Delay.
1.1.Executive Summary
This document describes the test methodology for measuring group delay and group delay variation ofdevices used in an HFC network.
1.2. Scope
The purpose of this test is to measure the group delay and group delay variation of a properly terminateddevice. This procedure is applicable to testing of 75 Q components.
1.3. Benefits
This document provides an industry-standard method for the measurement of group delay variation on RFproducts. Implementation of this standard method will allow for direct comparison of results performed indisparate locations and by different testers. This allows the broadband industry to have a standard
measurement technique by which all products are measured for this particular parameter.
1.4. Intended Audience
This document is intended for use by RF hardware development engineers or MSO engineers who wish tovalidate RF specifications.
1.5. Areas for Further Investigation or to be Added in Future VersionsFuture versions of this document may enhance the procedure or be updated to include more modernversions of test equipment as technology evolves over time.
