The Agilent/Keysight 83441A is a lightwave receiver module engineered for pulse parameter measurements on SONET/SDH optical waveforms. It converts optical signals to electrical output for direct connection to high-speed oscilloscopes, enabling precise optical pulse and eye diagram characterization. Originally manufactured by Agilent and now supported by Keysight, this legacy instrument remains in service across telecommunications test facilities despite its obsolete status.
– Technical Specifications
The 83441A functions as an optical-to-electrical transducer optimized for single-shot and sampling oscilloscope integration. Its design targets the measurement of fast optical transients and statistical eye patterns inherent to SONET/SDH transmission systems. The receiver module accepts optical input and produces electrical output scaled for oscilloscope input stages.
