Agilent 8504B Reflectometer

  Precision

The Agilent 8504B precision reflectometer provides state-of-the-art lightwave reflection measurements.
Individual reflections are measured and displayed as a function of distance or position.
Return loss measurements beyond 80 dB are achievable,
even when larger reflections are present in the measurement path.
Two reflections can be closer than 25 µm (equivalent distance in air) and still be individually identified.
