Overview
EN 50289-1-7:2001 is a CENELEC test-method standard for communication cables that specifies how to measure the velocity of propagation of finished cables used in analogue and digital systems. It defines electrical test methods (phase and group velocity), calibration and measurement procedures, and result reporting. This Part 1-7 standard is intended to be read in conjunction with EN 50289-1-1 (general electrical test requirements) and references EN 50289-1-11 and EN 50290-1-2 for related measurements and definitions.
Key topics and technical requirements
- Scope and definitions
- Covers phase velocity (νp), group velocity (νg) and propagation time derived from phase-constant measurements.
- Uses definitions in EN 50290-1-2.
- Test equipment
- Preferred: network analyser; alternatives: generator plus phase meter or vector voltmeter.
- Overall test setup accuracy shall be better than 1%.
- Use of baluns, terminators and impedance-matching devices to minimise port-to-cable mismatch.
- Sample preparation
- For symmetrical cables, maintain pair/quad twisting at cable ends when connecting to test equipment.
- Calibration and measurement
- Full phase-shift calibration over the specified frequency range using a linear frequency sweep.
- Measure phase shift of the cable under test at the same frequency points and correct results using calibration data.
- Phase unwrapping (transforming phase from ±π range into a monotonic function) is required for reliable β(f) extraction.
- Δf selection: Δf ≤ 0.05 × measured frequency range for group velocity computation.
- Calculation methods
- Formulas for β(f), phase velocity (νp = 2πf/β) and group velocity (finite-difference form) are provided.
- Resonance (open/short) method: derive propagation time from measured resonance frequencies and compute νp = L/T.
- Test report
- Mandatory inclusions: temperature, frequency range, sample length, and reported values (phase velocity, group velocity, propagation time/delay).
Applications and users
- Who uses it:
- Cable manufacturers (type approval, quality control)
- Independent test laboratories and certification bodies
- Network engineers and installers validating cable performance for analog/digital links
- Procurement and compliance teams requiring documented propagation parameters
- Practical uses:
- Characterising delay and timing in data and telecom links
- Verifying suitability of cables for high-speed digital signalling and matched-impedance installations
- Input to link design, TDR calibration, and transmission modelling
