Agilent 86140A Optical Spectrum Analyzer – Expert Repair, Service & Calibration

We provide specialized repair, calibration, and preventive maintenance services for the Agilent 86140A Optical Spectrum Analyzer (OSA) — a high-performance instrument essential for measuring and analyzing optical signals across a wide spectral range. Known for its accuracy and resolution bandwidth, the 86140A is widely used in optical R&D, telecom manufacturing, and lab environments. Our team of experienced engineers ensures your OSA performs to original factory standards with fast turnaround and traceable results.

Our Process: In-Depth Inspection, Precision Repair, and Calibration

Full Functional Diagnostics
Each Agilent 86140A unit undergoes a comprehensive diagnostic process. We begin by verifying wavelength accuracy, resolution bandwidth, noise floor, optical signal response, and trace repeatability. We inspect all hardware, including the internal monochromator, stepper motors, gratings, and optical bench alignment.

Repair of Common Faults
We resolve a wide range of common issues with the 86140A, including:

  • No optical signal detected or poor sensitivity

  • Incorrect or drifting wavelength readings

  • Faulty internal light source or grating mechanism

  • CRT or LCD display failure (if present)

  • Front panel control malfunction

  • Boot-up failure or firmware crashes

  • Damaged input ports or FC/APC connectors

Component-Level Electronics Repair
We perform detailed board-level diagnostics and repair on the power supply, mainboard, detector boards, and other internal electronics. Using precision soldering and part replacement, we restore functionality without compromising signal integrity.

Monochromator Alignment & Optical Cleaning
Accurate wavelength and amplitude measurements depend on a clean, properly aligned internal optical path. We inspect and align the monochromator assembly, clean the optics, replace worn fiber connectors, and ensure the unit meets factory alignment tolerances.

Internal Self-Test & Firmware Update
We run complete internal self-tests to validate system functions and ensure firmware stability. If needed, we update the firmware to the latest supported version to improve performance and compatibility.

NIST-Traceable Calibration
All serviced units receive a full NIST-traceable calibration, including:

  • Wavelength accuracy check with reference lasers

  • Dynamic range verification with calibrated optical sources

  • Resolution bandwidth and noise floor validation
    Calibration certificates with before/after performance data are provided with each unit.
