The Agilent/Keysight 8140A is an optical loss test set and power meter designed for optical signal measurement and characterization in transmission testing environments. Originally developed for precision optical power analysis, this instrument operates as a specialized measurement tool within Keysight’s optical test portfolio. Now obsolete, the 8140A represents an earlier generation of optical metrology equipment.
Technical Specifications
Classified as an optical loss test set/power meter, the 8140A provides optical power measurement capabilities. The instrument’s design reflects optical test and measurement principles consistent with contemporaneous Keysight optical instrumentation.
– Key Features
• Optical power measurement functionality
• Designed for optical loss characterization
• Integration within broader optical test systems
• Programmable operation for automated test sequences
– Typical Applications
The 8140A serves optical fiber and component testing environments requiring power level verification and loss measurement across optical transmission links. Applications include fiber optic system validation, component insertion loss analysis, and optical signal path characterization.
– Compatibility & Integration
As an obsolete instrument, modern integration presents significant challenges. Contemporary Keysight optical test equipment—including tunable laser sources and signal analyzers—represents current alternatives. The instrument’s interconnection capabilities and control protocols reflect standards from its original production era. Direct compatibility with current automated test frameworks requires assessment of legacy interface requirements and available integration methods.
Procurement of functional 8140A units is limited due to obsolescence. Organizations requiring optical loss and power measurement should evaluate current Keysight optical test solutions for equivalent or superior measurement capabilities.
