Overview

EN 2591-702:2001 is a CEN/AECMA aerospace test-method standard titled "Aerospace series - Elements of electrical and optical connection - Test methods - Part 702: Electrical elements - Measurement of signal distortion of couplers."
It specifies a repeatable method to measure signal distortion introduced by electrical couplers used in aerospace applications. The standard is intended to be used together with EN 2591-100 (general test-method provisions) and forms part of the aerospace series for electrical and optical connection elements.

Key topics and technical requirements

• Scope: Defines the measurement method for coupler-induced signal distortion; applies to electrical elements (couplers) used in aerospace systems.
• Test setup: Measurements are performed using a signal generator and an oscilloscope connected per the standard test arrangement (see referenced figure).
• Input signal: A square wave at 250 kHz is used by default (unless otherwise specified in the applicable technical specification).
• Signal edge requirements: Rise time and fall time shall be ≤ 100 ns, measured between 10% and 90% of peak amplitude.
• Measured parameters:
  • Distortion S (output waveform deviation as defined in the standard)
  • Drop percentage D (amplitude drop as specified)
  • Test temperature - test conditions must be stated when not defined by the product specification.
• Conformance: Distortion S and drop percentage D must meet the values specified in the product’s technical specification or procurement requirements.
• Normative reference: EN 2591-100 provides the general test-method framework to be applied in conjunction with this part.

Practical applications and users

This standard is directly applicable to:

• Aerospace component manufacturers designing and qualifying electrical couplers and connectors.
• Test laboratories performing acceptance, qualification, or comparative testing of couplers for avionics and flight hardware.
• Quality assurance and procurement teams who need objective, standardized criteria for signal integrity and coupler performance.
• Design and systems engineers specifying connector and coupler requirements in avionics, flight control, communication and sensor interfaces.

Using EN 2591-702:2001 helps ensure measurable, reproducible evaluation of coupler effects on digital signals, aiding compatibility, reliability, and signal integrity in aerospace systems.
