Agilent 8504B Precision Reflectometer
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 (e distance in air) and still be individually identified.
