IEEE 370-2020

This document addresses the quality of measured S-parameters for electrical printed circuit board (PCB) and related interconnect at frequencies up to 50 GHz. This might include, but is not limited to: test fixtures, as well as methods and processes for controlling the accuracy and consistency of measured data for broadband signals with frequency content up to 50 GHz. The standard is applicable to: -PCB and related interconnects (including package, connector, cable, etc.) used in high speed digital applications, operating with signals at frequencies up to 50 GHz. -Most industries using such interconnects; -Major measurement approaches (Time Domain or Frequency Domain) for collecting S-Parameter data; -Significant methods of removing/de-embedding fixture and instrumentation effects.
