Data record std.tia-526-7-a.definition.reflectance

Verified 2026-10-25 Confidence: High

Clause 3.1.12 of ANSI/TIA-526-7-A (2015) defines reflectance as the reflected-to-incident power ratio of a single discrete component, written as a negative decibel figure, and observes that IEC 61300-3-6 uses the term return loss for the same quantity expressed with a positive sign.
