The HP/Agilent 83402A is a lightwave source designed for optical component and system characterization across research, development, and manufacturing environments. Operating from 300 kHz to 6 GHz, it delivers stable optical signals at 1300 nm nominal wavelength into 9/125 µm single-mode fiber. The instrument supports external RF modulation up to 6 GHz and integrates directly with Agilent HP 8702B and HP 8703A Lightwave Component Analyzers, functioning as a frequency-swept intensity modulation source for network and component analysis.

– Compatibility & Integration
Designed as an accessory for the HP 8702 Series Lightwave Component Analyzers, specifically the HP 8702B (850/1300/1550 nm) and HP 8703A (1300/1550 nm). Operates in conjunction with these analyzers by providing the modulated optical signal while the analyzer sweeps the RF modulation frequency across the selected bandwidth. Optional optical interface connectors available separately (Agilent 81000xI Series).
