The HP Agilent 83447A Lightwave Trigger converts optical waveforms into electrical trigger signals for precise timing reference in optical signal analysis. Operating across 1200 nm to 1600 nm, it extracts clock timing from NRZ data streams ranging from 50 Mb/s to 2.5 Gb/s—eliminating the need for external electrical clock signals. This capability makes it essential for eye-diagram analysis and high-speed optical characterization in telecommunications and development environments.
