Description (English):

IEC 62783-1-1:2022 specifies time domain test methods, parameters and requirements for fixtures for twinax cables (known also as twin-axial cables or twin-coaxial cables) used in digital communication systems. The methods and fixtures facilitate measurements of differential and common mode transmission parameters as well as single-ended mode parameters. This document is applicable to twinax cables and also to symmetric cables with pitch.

Abstract

Overview

IEC 62783-1-1:2022 - Twinax cables for digital communications - Part 1-1: Time domain test methods - General requirements - specifies time-domain test methods, parameters and requirements for test fixtures used with twinax (twin‑axial / twin‑coaxial) cables and symmetric cables with pitch. The standard defines how to measure differential, common‑mode and single‑ended transmission parameters using time‑domain techniques (TDR/TDT), and sets requirements for test equipment, fixtures, calibration and reporting to support reliable signal integrity assessment at high data rates.

Key topics and technical requirements

Time‑domain methods: Defines Time Domain Reflectometer (TDR) and Time Domain Transmission (TDT) measurement approaches and how time‑domain displays (voltage/impedance vs time or electrical length) are used to locate and quantify discontinuities.
Measurement equipment: Preferred setups include a sampling oscilloscope with dual‑channel TDR modules (two 2‑channel modules) or a 4‑port Vector Network Analyser (VNA) with time‑domain capability via IDFT (per IEC 62153‑1‑1).
Test leads and cables: Use four phase‑stable, low‑loss 50 Ω coaxial leads of equal electrical length (cable length should be as short as possible, typically
